Remove ioctl-based procfs support on Solaris This is the previously mentioned patch to get rid of unstructured/ioctl-based procfs support in procfs.c. Given that support for structured procfs was introduced in Solaris 2.6 back in 1997 and we're just removing support for Solaris < 10, there's no point in carrying that baggage (and tons of support for IRIX and OSF/1 as well) around any longer. Most of the patch should be straightforward (removing support for !NEW_PROC_API, non-Solaris OSes and pre-Solaris 10 quirks). Only a few points need explanations: * <sys/syscall.h> was already included unconditionally in most places, so there's no need to have guards in a few remaining ones. * configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so NEW_PROC_API detection for those in configure.ac can go. * I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1. Theoretically, it would be better to include <procfs.h> on Solaris (which includes that define), but that breaks the build over <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux. * I've regenerated syscall_table[] in proc-events.c with a small script from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no traces of older Solaris versions and other OSes left. * prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX doesn't use procfs.c any longer, so all related code can go. The patch was generated with diff -w so one can easier see changes without being distracted by simple reindentations. So far, it has only been compiled and smoke-tested on amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and x86_64-pc-linux-gnu. Certainly needs more testing (Solaris 11.3 vs. 11.4, 32-bit gdb, testsuite once I've figured out what's wrong on Solaris 10 etc.), but it's enough to get a first impression how much cleanup is possible here. * configure.ac Don't check for sys/fault.h, sys/syscall.h, sys/proc.h. (NEW_PROC_API): Remove. (prsysent_t, pr_sigset_t, pr_sigaction64_t, pr_siginfo64_t): Likewise. * common/common.m4 (GDB_AC_COMMON): Don't check for sys/syscall.h. * configure: Regenerate. * config.in: Regenerate. * gdbserver/configure: Regenerate. * gdbserver/config.in: Regenerate. * i386-sol2-nat.c (_initialize_amd64_sol2_nat): Remove NEW_PROC_API test. * sparc-sol2-nat.c (_initialize_sparc_sol2_nat): Likewise. * linux-btrace.c: Remove HAVE_SYS_SYSCALL_H test. * proc-api.c: Remove !NEW_PROC_API support.

/* This module provides the interface between GDB and the
/proc file system, which is used on many versions of Unix
as a means for debuggers to control other processes.
/proc works by imitating a file system: you open a simulated file
that represents the process you wish to interact with, and perform
operations on that "file" in order to examine or change the state
of the other process.
The most important thing to know about /proc and this module is
that there are two very different interfaces to /proc:
One that uses the ioctl system call, and another that uses read
and write system calls.
Remove ioctl-based procfs support on Solaris This is the previously mentioned patch to get rid of unstructured/ioctl-based procfs support in procfs.c. Given that support for structured procfs was introduced in Solaris 2.6 back in 1997 and we're just removing support for Solaris < 10, there's no point in carrying that baggage (and tons of support for IRIX and OSF/1 as well) around any longer. Most of the patch should be straightforward (removing support for !NEW_PROC_API, non-Solaris OSes and pre-Solaris 10 quirks). Only a few points need explanations: * <sys/syscall.h> was already included unconditionally in most places, so there's no need to have guards in a few remaining ones. * configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so NEW_PROC_API detection for those in configure.ac can go. * I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1. Theoretically, it would be better to include <procfs.h> on Solaris (which includes that define), but that breaks the build over <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux. * I've regenerated syscall_table[] in proc-events.c with a small script from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no traces of older Solaris versions and other OSes left. * prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX doesn't use procfs.c any longer, so all related code can go. The patch was generated with diff -w so one can easier see changes without being distracted by simple reindentations. So far, it has only been compiled and smoke-tested on amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and x86_64-pc-linux-gnu. Certainly needs more testing (Solaris 11.3 vs. 11.4, 32-bit gdb, testsuite once I've figured out what's wrong on Solaris 10 etc.), but it's enough to get a first impression how much cleanup is possible here. * configure.ac Don't check for sys/fault.h, sys/syscall.h, sys/proc.h.

constify to_detach This patch constifies the target_ops method to_detach. This is a small cleanup, but also, I think, a bug-prevention fix, since gdb already acts as if the "args" argument here was const. In particular, top.c:quit_force calls kill_or_detach via iterate_over_inferiors. kill_or_detach calls target_detach, passing the same argument each time. So, if one of these methods was not const-correct, then kill_or_detach would change its behavior in a strange way. I could not build every target I modified in this patch. I've inspected them all by hand, though. Many targets do not use the "args" parameter; a couple pass it to atoi; and a few pass it on to the to_detach method of the target beneath. The only code that required a real change was in linux-nat.c, and that only needed the introduction of a temporary variable for const-correctness. 2013-11-08 Tom Tromey <tromey@redhat.com> * aix-thread.c (aix_thread_detach): Update. * corelow.c (core_detach): Update. * darwin-nat.c (darwin_detach): Update. * dec-thread.c (dec_thread_detach): Update. * gnu-nat.c (gnu_detach): Update. * go32-nat.c (go32_detach): Update. * inf-ptrace.c (inf_ptrace_detach): Update. * inf-ttrace.c (inf_ttrace_detach): Update. * linux-fork.c (linux_fork_detach): Update. * linux-fork.h (linux_fork_detach): Update. * linux-nat.c (linux_nat_detach): Update.

The issue is that we don't currently distinguish send "interrupt/ctrl-c" to target terminal vs "stop/pause" thread well; both cases go through "target_stop". And then, the native Linux backend (linux-nat.c) implements target_stop with SIGSTOP in non-stop mode, and SIGINT in all-stop mode. Since "maint set target-non-stop on" forces the backend to be always running in non-stop mode, even though the user-visible behavior is "set non-stop" is "off", "interrupt" causes a SIGSTOP instead of the SIGINT the test expects. Fix this by introducing a target_interrupt method to use in the "interrupt/ctrl-c" case, so "set non-stop off" can always work the same irrespective of "maint set target-non-stop on/off". I'm explictly considering changing the "set non-stop on" behavior as out of scope here. Most of the patch is an across-the-board rename of to_stop hook implementations to to_interrupt. The only targets where something more than a rename is being done are linux-nat.c and remote.c, which are the only targets that support async, and thus are the only ones the core side calls target_stop on. gdb/ChangeLog: 2015-08-07 Pedro Alves <palves@redhat.com> * darwin-nat.c (darwin_stop): Rename to ...

2000-05-28 03:12:42 +02:00
Push pruning old threads down to the target When GDB wants to sync the thread list with the target's (e.g., due to "info threads"), it calls update_thread_list: update_thread_list (void) { prune_threads (); target_find_new_threads (); update_threads_executing (); } And then prune_threads does: prune_threads (void) { struct thread_info *tp, *next; for (tp = thread_list; tp; tp = next) { next = tp->next; if (!thread_alive (tp)) delete_thread (tp->ptid); } } Calling thread_live on each thread one by one is expensive. E.g., on Linux, it ends up doing kill(SIG0) once for each thread. Not a big deal, but still a bunch of syscalls... With the remote target, it's cumbersome. That thread_alive call ends up generating one T packet per thread: Sending packet: $Tp2141.2150#82...Packet received: OK Sending packet: $Tp2141.214f#b7...Packet received: OK Sending packet: $Tp2141.2141#82...Packet received: OK Sending packet: $qXfer:threads:read::0,fff#03...Packet received: l<threads>\n<thread id="p2141.2141" core="2"/>\n<thread id="p2141.214f" core="1"/>\n<thread id="p2141.2150" core="2"/>\n</threads>\n That seems a bit silly when target_find_new_threads method implementations will always fetch the whole current set of target threads, and then add those that are not in GDB's thread list, to GDB's thread list. This patch thus pushes down the responsibility of pruning dead threads to the target_find_new_threads method instead, so a target may implement pruning dead threads however it wants. Once we do that, target_find_new_threads becomes a misnomer, so the patch renames it to target_update_thread_list. The patch doesn't attempt to do any optimization to any target yet. It simply exports prune_threads, and makes all implementations of target_update_thread_list call that. It's meant to be a no-op. gdb/ 2014-10-15 Pedro Alves <palves@redhat.com> * ada-tasks.c (print_ada_task_info, task_command_1): Adjust. * bsd-uthread.c (bsd_uthread_find_new_threads): Rename to ...

Remove ioctl-based procfs support on Solaris This is the previously mentioned patch to get rid of unstructured/ioctl-based procfs support in procfs.c. Given that support for structured procfs was introduced in Solaris 2.6 back in 1997 and we're just removing support for Solaris < 10, there's no point in carrying that baggage (and tons of support for IRIX and OSF/1 as well) around any longer. Most of the patch should be straightforward (removing support for !NEW_PROC_API, non-Solaris OSes and pre-Solaris 10 quirks). Only a few points need explanations: * <sys/syscall.h> was already included unconditionally in most places, so there's no need to have guards in a few remaining ones. * configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so NEW_PROC_API detection for those in configure.ac can go. * I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1. Theoretically, it would be better to include <procfs.h> on Solaris (which includes that define), but that breaks the build over <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux. * I've regenerated syscall_table[] in proc-events.c with a small script from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no traces of older Solaris versions and other OSes left. * prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX doesn't use procfs.c any longer, so all related code can go. The patch was generated with diff -w so one can easier see changes without being distracted by simple reindentations. So far, it has only been compiled and smoke-tested on amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and x86_64-pc-linux-gnu. Certainly needs more testing (Solaris 11.3 vs. 11.4, 32-bit gdb, testsuite once I've figured out what's wrong on Solaris 10 etc.), but it's enough to get a first impression how much cleanup is possible here. * configure.ac Don't check for sys/fault.h, sys/syscall.h, sys/proc.h.

Mostly trivial enum fixes This is a patch I extracted from Pedro's C++ branch. It contains the most trivial enum fixes, where an integer type/value was used instead of the appropriate enum type/value. It fixes many C++ errors, since in C++ you can't mix integers and enums implicitely. Regardless of the C++ conversion, I think this is a good cleanup to make use of the appropriate enum types.

The issue is that we don't currently distinguish send "interrupt/ctrl-c" to target terminal vs "stop/pause" thread well; both cases go through "target_stop". And then, the native Linux backend (linux-nat.c) implements target_stop with SIGSTOP in non-stop mode, and SIGINT in all-stop mode. Since "maint set target-non-stop on" forces the backend to be always running in non-stop mode, even though the user-visible behavior is "set non-stop" is "off", "interrupt" causes a SIGSTOP instead of the SIGINT the test expects. Fix this by introducing a target_interrupt method to use in the "interrupt/ctrl-c" case, so "set non-stop off" can always work the same irrespective of "maint set target-non-stop on/off". I'm explictly considering changing the "set non-stop on" behavior as out of scope here. Most of the patch is an across-the-board rename of to_stop hook implementations to to_interrupt. The only targets where something more than a rename is being done are linux-nat.c and remote.c, which are the only targets that support async, and thus are the only ones the core side calls target_stop on. gdb/ChangeLog: 2015-08-07 Pedro Alves <palves@redhat.com> * darwin-nat.c (darwin_stop): Rename to ...

Push pruning old threads down to the target When GDB wants to sync the thread list with the target's (e.g., due to "info threads"), it calls update_thread_list: update_thread_list (void) { prune_threads (); target_find_new_threads (); update_threads_executing (); } And then prune_threads does: prune_threads (void) { struct thread_info *tp, *next; for (tp = thread_list; tp; tp = next) { next = tp->next; if (!thread_alive (tp)) delete_thread (tp->ptid); } } Calling thread_live on each thread one by one is expensive. E.g., on Linux, it ends up doing kill(SIG0) once for each thread. Not a big deal, but still a bunch of syscalls... With the remote target, it's cumbersome. That thread_alive call ends up generating one T packet per thread: Sending packet: $Tp2141.2150#82...Packet received: OK Sending packet: $Tp2141.214f#b7...Packet received: OK Sending packet: $Tp2141.2141#82...Packet received: OK Sending packet: $qXfer:threads:read::0,fff#03...Packet received: l<threads>\n<thread id="p2141.2141" core="2"/>\n<thread id="p2141.214f" core="1"/>\n<thread id="p2141.2150" core="2"/>\n</threads>\n That seems a bit silly when target_find_new_threads method implementations will always fetch the whole current set of target threads, and then add those that are not in GDB's thread list, to GDB's thread list. This patch thus pushes down the responsibility of pruning dead threads to the target_find_new_threads method instead, so a target may implement pruning dead threads however it wants. Once we do that, target_find_new_threads becomes a misnomer, so the patch renames it to target_update_thread_list. The patch doesn't attempt to do any optimization to any target yet. It simply exports prune_threads, and makes all implementations of target_update_thread_list call that. It's meant to be a no-op. gdb/ 2014-10-15 Pedro Alves <palves@redhat.com> * ada-tasks.c (print_ada_task_info, task_command_1): Adjust. * bsd-uthread.c (bsd_uthread_find_new_threads): Rename to ...

Remove ioctl-based procfs support on Solaris This is the previously mentioned patch to get rid of unstructured/ioctl-based procfs support in procfs.c. Given that support for structured procfs was introduced in Solaris 2.6 back in 1997 and we're just removing support for Solaris < 10, there's no point in carrying that baggage (and tons of support for IRIX and OSF/1 as well) around any longer. Most of the patch should be straightforward (removing support for !NEW_PROC_API, non-Solaris OSes and pre-Solaris 10 quirks). Only a few points need explanations: * <sys/syscall.h> was already included unconditionally in most places, so there's no need to have guards in a few remaining ones. * configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so NEW_PROC_API detection for those in configure.ac can go. * I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1. Theoretically, it would be better to include <procfs.h> on Solaris (which includes that define), but that breaks the build over <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux. * I've regenerated syscall_table[] in proc-events.c with a small script from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no traces of older Solaris versions and other OSes left. * prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX doesn't use procfs.c any longer, so all related code can go. The patch was generated with diff -w so one can easier see changes without being distracted by simple reindentations. So far, it has only been compiled and smoke-tested on amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and x86_64-pc-linux-gnu. Certainly needs more testing (Solaris 11.3 vs. 11.4, 32-bit gdb, testsuite once I've figured out what's wrong on Solaris 10 etc.), but it's enough to get a first impression how much cleanup is possible here. * configure.ac Don't check for sys/fault.h, sys/syscall.h, sys/proc.h.

/* =================== STRUCT PROCINFO "MODULE" =================== */
/* FIXME: this comment will soon be out of date W.R.T. threads. */
/* The procinfo struct is a wrapper to hold all the state information
concerning a /proc process. There should be exactly one procinfo
for each process, and since GDB currently can debug only one
process at a time, that means there should be only one procinfo.
All of the LWP's of a process can be accessed indirectly thru the
single process procinfo.
However, against the day when GDB may debug more than one process,
this data structure is kept in a list (which for now will hold no
more than one member), and many functions will have a pointer to a
procinfo as an argument.
There will be a separate procinfo structure for use by the (not yet
implemented) "info proc" command, so that we can print useful
information about any random process without interfering with the
inferior's procinfo information. */

Remove ioctl-based procfs support on Solaris This is the previously mentioned patch to get rid of unstructured/ioctl-based procfs support in procfs.c. Given that support for structured procfs was introduced in Solaris 2.6 back in 1997 and we're just removing support for Solaris < 10, there's no point in carrying that baggage (and tons of support for IRIX and OSF/1 as well) around any longer. Most of the patch should be straightforward (removing support for !NEW_PROC_API, non-Solaris OSes and pre-Solaris 10 quirks). Only a few points need explanations: * <sys/syscall.h> was already included unconditionally in most places, so there's no need to have guards in a few remaining ones. * configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so NEW_PROC_API detection for those in configure.ac can go. * I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1. Theoretically, it would be better to include <procfs.h> on Solaris (which includes that define), but that breaks the build over <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux. * I've regenerated syscall_table[] in proc-events.c with a small script from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no traces of older Solaris versions and other OSes left. * prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX doesn't use procfs.c any longer, so all related code can go. The patch was generated with diff -w so one can easier see changes without being distracted by simple reindentations. So far, it has only been compiled and smoke-tested on amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and x86_64-pc-linux-gnu. Certainly needs more testing (Solaris 11.3 vs. 11.4, 32-bit gdb, testsuite once I've figured out what's wrong on Solaris 10 etc.), but it's enough to get a first impression how much cleanup is possible here. * configure.ac Don't check for sys/fault.h, sys/syscall.h, sys/proc.h.

Remove ioctl-based procfs support on Solaris This is the previously mentioned patch to get rid of unstructured/ioctl-based procfs support in procfs.c. Given that support for structured procfs was introduced in Solaris 2.6 back in 1997 and we're just removing support for Solaris < 10, there's no point in carrying that baggage (and tons of support for IRIX and OSF/1 as well) around any longer. Most of the patch should be straightforward (removing support for !NEW_PROC_API, non-Solaris OSes and pre-Solaris 10 quirks). Only a few points need explanations: * <sys/syscall.h> was already included unconditionally in most places, so there's no need to have guards in a few remaining ones. * configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so NEW_PROC_API detection for those in configure.ac can go. * I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1. Theoretically, it would be better to include <procfs.h> on Solaris (which includes that define), but that breaks the build over <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux. * I've regenerated syscall_table[] in proc-events.c with a small script from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no traces of older Solaris versions and other OSes left. * prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX doesn't use procfs.c any longer, so all related code can go. The patch was generated with diff -w so one can easier see changes without being distracted by simple reindentations. So far, it has only been compiled and smoke-tested on amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and x86_64-pc-linux-gnu. Certainly needs more testing (Solaris 11.3 vs. 11.4, 32-bit gdb, testsuite once I've figured out what's wrong on Solaris 10 etc.), but it's enough to get a first impression how much cleanup is possible here. * configure.ac Don't check for sys/fault.h, sys/syscall.h, sys/proc.h.

/* This function is getting ALMOST long enough to break up into
several. Here is some rationale:
There are several file descriptors that may need to be open
for any given process or LWP. The ones we're intereted in are:
- control (ctl) write-only change the state
- status (status) read-only query the state
- address space (as) read/write access memory
- map (map) read-only virtual addr map
Most of these are opened lazily as they are needed.
The pathnames for the 'files' for an LWP look slightly
different from those of a first-class process:
Pathnames for a process (<proc-id>):
/proc/<proc-id>/ctl
/proc/<proc-id>/status
/proc/<proc-id>/as
/proc/<proc-id>/map
Pathnames for an LWP (lwp-id):
/proc/<proc-id>/lwp/<lwp-id>/lwpctl
/proc/<proc-id>/lwp/<lwp-id>/lwpstatus
An LWP has no map or address space file descriptor, since
Remove ioctl-based procfs support on Solaris This is the previously mentioned patch to get rid of unstructured/ioctl-based procfs support in procfs.c. Given that support for structured procfs was introduced in Solaris 2.6 back in 1997 and we're just removing support for Solaris < 10, there's no point in carrying that baggage (and tons of support for IRIX and OSF/1 as well) around any longer. Most of the patch should be straightforward (removing support for !NEW_PROC_API, non-Solaris OSes and pre-Solaris 10 quirks). Only a few points need explanations: * <sys/syscall.h> was already included unconditionally in most places, so there's no need to have guards in a few remaining ones. * configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so NEW_PROC_API detection for those in configure.ac can go. * I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1. Theoretically, it would be better to include <procfs.h> on Solaris (which includes that define), but that breaks the build over <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux. * I've regenerated syscall_table[] in proc-events.c with a small script from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no traces of older Solaris versions and other OSes left. * prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX doesn't use procfs.c any longer, so all related code can go. The patch was generated with diff -w so one can easier see changes without being distracted by simple reindentations. So far, it has only been compiled and smoke-tested on amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and x86_64-pc-linux-gnu. Certainly needs more testing (Solaris 11.3 vs. 11.4, 32-bit gdb, testsuite once I've figured out what's wrong on Solaris 10 etc.), but it's enough to get a first impression how much cleanup is possible here. * configure.ac Don't check for sys/fault.h, sys/syscall.h, sys/proc.h.

Replace some xmalloc-family functions with XNEW-family ones This patch is part of the make-gdb-buildable-in-C++ effort. The idea is to change some calls to the xmalloc family of functions to calls to the equivalents in the XNEW family. This avoids adding an explicit cast, so it keeps the code a bit more readable. Some of them also map relatively well to a C++ equivalent (XNEW (struct foo) -> new foo), so it will be possible to do scripted replacements if needed. I only changed calls that were obviously allocating memory for one or multiple "objects". Allocation of variable sizes (such as strings or buffer handling) will be for later (and won't use XNEW). - xmalloc (sizeof (struct foo)) -> XNEW (struct foo) - xmalloc (num * sizeof (struct foo)) -> XNEWVEC (struct foo, num) - xcalloc (1, sizeof (struct foo)) -> XCNEW (struct foo) - xcalloc (num, sizeof (struct foo)) -> XCNEWVEC (struct foo, num) - xrealloc (p, num * sizeof (struct foo) -> XRESIZEVEC (struct foo, p, num) - obstack_alloc (ob, sizeof (struct foo)) -> XOBNEW (ob, struct foo) - obstack_alloc (ob, num * sizeof (struct foo)) -> XOBNEWVEC (ob, struct foo, num) - alloca (sizeof (struct foo)) -> XALLOCA (struct foo) - alloca (num * sizeof (struct foo)) -> XALLOCAVEC (struct foo, num) Some instances of xmalloc followed by memset to zero the buffer were replaced by XCNEW or XCNEWVEC. I regtested on x86-64, Ubuntu 14.04, but the patch touches many architecture-specific files. For those I'll have to rely on the buildbot or people complaining that I broke their gdb. gdb/ChangeLog: * aarch64-linux-nat.c (aarch64_add_process): Likewise. * aarch64-tdep.c (aarch64_gdbarch_init): Likewise. * ada-exp.y (write_ambiguous_var): Likewise. * ada-lang.c (resolve_subexp): Likewise.

Fix gdb C++ compilation on Solaris (PR build/20712) gdb 7.12 doesn't compile as C++ (tried with g++ 4.9) on Solaris (tried 10 and 12, sparc and x86). The following patch (relative to the 7.12 release, though I expect most if not all issues to be present on trunk, too) fixes this. Only a few of the changes bear explanation: * Initially, compilation failed whereever defs.h. was included: In file included from /vol/src/gnu/gdb/gdb-7.12/gdb/gdb.c:19:0: /vol/src/gnu/gdb/gdb-7.12/gdb/defs.h:630:33: error: 'double atof(const char*)' conflicts with a previous declaration extern double atof (const char *); /* X3.159-1989 4.10.1.1 */ ^ In file included from /usr/include/stdlib.h:17:0, from build-gnulib/import/stdlib.h:36, from /vol/src/gnu/gdb/gdb-7.12/gdb/common/common-defs.h:32, from /vol/src/gnu/gdb/gdb-7.12/gdb/defs.h:28, from /vol/src/gnu/gdb/gdb-7.12/gdb/gdb.c:19: /vol/gcc-4.9/lib/gcc/i386-pc-solaris2.10/4.9.0/include-fixed/iso/stdlib_iso.h:119:15: note: previous declaration 'double std::atof(const char*)' extern double atof(const char *); ^ This is due to this gem in gdb/defs.h which seems to have been present like forever: #ifndef atof extern double atof (const char *); /* X3.159-1989 4.10.1.1 */ #endif In the Solaris headers, the appropriate functions are in namespace std, thus the conflict. I've wrapped the defs.h declaration in !__cplusplus to avoid this; perhaps it can go completely instead. * All the casts are necessary to appease g++ and should be pretty obvious. * The sol-thread.c changes are here to handle /vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c: In function 'void _initialize_sol_thread()': /vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c:1252:36: error: invalid conversion from 'void*' to 'void (*)(int)' [-fpermissive] if (!(p_##X = dlsym (dlhandle, #X))) \ ^ /vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c:1255:3: note: in expansion of macro 'resolve' resolve (td_log); ^ and are modeled after linux-thread-db.c (try_thread_db_load_1). The patch allowed both 32 and 64-bit C++ builds on sparc-sun-solaris2.10 and i386-pc-solaris2.10 to complete. The resulting binary hasn't seen more than a smoke test (invoke it on itself, b main, run) yet.

Remove ioctl-based procfs support on Solaris This is the previously mentioned patch to get rid of unstructured/ioctl-based procfs support in procfs.c. Given that support for structured procfs was introduced in Solaris 2.6 back in 1997 and we're just removing support for Solaris < 10, there's no point in carrying that baggage (and tons of support for IRIX and OSF/1 as well) around any longer. Most of the patch should be straightforward (removing support for !NEW_PROC_API, non-Solaris OSes and pre-Solaris 10 quirks). Only a few points need explanations: * <sys/syscall.h> was already included unconditionally in most places, so there's no need to have guards in a few remaining ones. * configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so NEW_PROC_API detection for those in configure.ac can go. * I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1. Theoretically, it would be better to include <procfs.h> on Solaris (which includes that define), but that breaks the build over <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux. * I've regenerated syscall_table[] in proc-events.c with a small script from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no traces of older Solaris versions and other OSes left. * prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX doesn't use procfs.c any longer, so all related code can go. The patch was generated with diff -w so one can easier see changes without being distracted by simple reindentations. So far, it has only been compiled and smoke-tested on amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and x86_64-pc-linux-gnu. Certainly needs more testing (Solaris 11.3 vs. 11.4, 32-bit gdb, testsuite once I've figured out what's wrong on Solaris 10 etc.), but it's enough to get a first impression how much cleanup is possible here. * configure.ac Don't check for sys/fault.h, sys/syscall.h, sys/proc.h.

/* This "module" is the interface layer between the /proc system API
and the gdb target vector functions. This layer consists of access
functions that encapsulate each of the basic operations that we
need to use from the /proc API.
The main motivation for this layer is to hide the fact that there
are two very different implementations of the /proc API. Rather
than have a bunch of #ifdefs all thru the gdb target vector
functions, we do our best to hide them all in here. */
Remove ioctl-based procfs support on Solaris This is the previously mentioned patch to get rid of unstructured/ioctl-based procfs support in procfs.c. Given that support for structured procfs was introduced in Solaris 2.6 back in 1997 and we're just removing support for Solaris < 10, there's no point in carrying that baggage (and tons of support for IRIX and OSF/1 as well) around any longer. Most of the patch should be straightforward (removing support for !NEW_PROC_API, non-Solaris OSes and pre-Solaris 10 quirks). Only a few points need explanations: * <sys/syscall.h> was already included unconditionally in most places, so there's no need to have guards in a few remaining ones. * configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so NEW_PROC_API detection for those in configure.ac can go. * I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1. Theoretically, it would be better to include <procfs.h> on Solaris (which includes that define), but that breaks the build over <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux. * I've regenerated syscall_table[] in proc-events.c with a small script from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no traces of older Solaris versions and other OSes left. * prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX doesn't use procfs.c any longer, so all related code can go. The patch was generated with diff -w so one can easier see changes without being distracted by simple reindentations. So far, it has only been compiled and smoke-tested on amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and x86_64-pc-linux-gnu. Certainly needs more testing (Solaris 11.3 vs. 11.4, 32-bit gdb, testsuite once I've figured out what's wrong on Solaris 10 etc.), but it's enough to get a first impression how much cleanup is possible here. * configure.ac Don't check for sys/fault.h, sys/syscall.h, sys/proc.h.

Only a few points need explanations: * <sys/syscall.h> was already included unconditionally in most places, so there's no need to have guards in a few remaining ones. * configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so NEW_PROC_API detection for those in configure.ac can go. * I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1. Theoretically, it would be better to include <procfs.h> on Solaris (which includes that define), but that breaks the build over <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux. * I've regenerated syscall_table[] in proc-events.c with a small script from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no traces of older Solaris versions and other OSes left. * prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX doesn't use procfs.c any longer, so all related code can go. The patch was generated with diff -w so one can easier see changes without being distracted by simple reindentations. So far, it has only been compiled and smoke-tested on amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and x86_64-pc-linux-gnu. Certainly needs more testing (Solaris 11.3 vs. 11.4, 32-bit gdb, testsuite once I've figured out what's wrong on Solaris 10 etc.), but it's enough to get a first impression how much cleanup is possible here. * configure.ac Don't check for sys/fault.h, sys/syscall.h, sys/proc.h.

Remove ioctl-based procfs support on Solaris This is the previously mentioned patch to get rid of unstructured/ioctl-based procfs support in procfs.c. Given that support for structured procfs was introduced in Solaris 2.6 back in 1997 and we're just removing support for Solaris < 10, there's no point in carrying that baggage (and tons of support for IRIX and OSF/1 as well) around any longer. Most of the patch should be straightforward (removing support for !NEW_PROC_API, non-Solaris OSes and pre-Solaris 10 quirks). Only a few points need explanations: * <sys/syscall.h> was already included unconditionally in most places, so there's no need to have guards in a few remaining ones. * configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so NEW_PROC_API detection for those in configure.ac can go. * I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1. Theoretically, it would be better to include <procfs.h> on Solaris (which includes that define), but that breaks the build over <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux. * I've regenerated syscall_table[] in proc-events.c with a small script from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no traces of older Solaris versions and other OSes left. * prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX doesn't use procfs.c any longer, so all related code can go. The patch was generated with diff -w so one can easier see changes without being distracted by simple reindentations. So far, it has only been compiled and smoke-tested on amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and x86_64-pc-linux-gnu.

Remove ioctl-based procfs support on Solaris This is the previously mentioned patch to get rid of unstructured/ioctl-based procfs support in procfs.c. Given that support for structured procfs was introduced in Solaris 2.6 back in 1997 and we're just removing support for Solaris < 10, there's no point in carrying that baggage (and tons of support for IRIX and OSF/1 as well) around any longer. Most of the patch should be straightforward (removing support for !NEW_PROC_API, non-Solaris OSes and pre-Solaris 10 quirks). Only a few points need explanations: * <sys/syscall.h> was already included unconditionally in most places, so there's no need to have guards in a few remaining ones. * configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so NEW_PROC_API detection for those in configure.ac can go. * I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1. Theoretically, it would be better to include <procfs.h> on Solaris (which includes that define), but that breaks the build over <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux. * I've regenerated syscall_table[] in proc-events.c with a small script from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no traces of older Solaris versions and other OSes left. * prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX doesn't use procfs.c any longer, so all related code can go. The patch was generated with diff -w so one can easier see changes without being distracted by simple reindentations. So far, it has only been compiled and smoke-tested on amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and x86_64-pc-linux-gnu. Certainly needs more testing (Solaris 11.3 vs. 11.4, 32-bit gdb, testsuite once I've figured out what's wrong on Solaris 10 etc.), but it's enough to get a first impression how much cleanup is possible here. * configure.ac Don't check for sys/fault.h, sys/syscall.h, sys/proc.h.

Only a few points need explanations: * <sys/syscall.h> was already included unconditionally in most places, so there's no need to have guards in a few remaining ones. * configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so NEW_PROC_API detection for those in configure.ac can go. * I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1. Theoretically, it would be better to include <procfs.h> on Solaris (which includes that define), but that breaks the build over <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux. * I've regenerated syscall_table[] in proc-events.c with a small script from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no traces of older Solaris versions and other OSes left. * prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX doesn't use procfs.c any longer, so all related code can go. The patch was generated with diff -w so one can easier see changes without being distracted by simple reindentations. So far, it has only been compiled and smoke-tested on amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and x86_64-pc-linux-gnu. Certainly needs more testing (Solaris 11.3 vs. 11.4, 32-bit gdb, testsuite once I've figured out what's wrong on Solaris 10 etc.), but it's enough to get a first impression how much cleanup is possible here. * configure.ac Don't check for sys/fault.h, sys/syscall.h, sys/proc.h.

Remove ioctl-based procfs support on Solaris This is the previously mentioned patch to get rid of unstructured/ioctl-based procfs support in procfs.c. Given that support for structured procfs was introduced in Solaris 2.6 back in 1997 and we're just removing support for Solaris < 10, there's no point in carrying that baggage (and tons of support for IRIX and OSF/1 as well) around any longer. Most of the patch should be straightforward (removing support for !NEW_PROC_API, non-Solaris OSes and pre-Solaris 10 quirks). Only a few points need explanations: * <sys/syscall.h> was already included unconditionally in most places, so there's no need to have guards in a few remaining ones. * configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so NEW_PROC_API detection for those in configure.ac can go. * I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1. Theoretically, it would be better to include <procfs.h> on Solaris (which includes that define), but that breaks the build over <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux. * I've regenerated syscall_table[] in proc-events.c with a small script from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no traces of older Solaris versions and other OSes left. * prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX doesn't use procfs.c any longer, so all related code can go. The patch was generated with diff -w so one can easier see changes without being distracted by simple reindentations.

Remove ioctl-based procfs support on Solaris This is the previously mentioned patch to get rid of unstructured/ioctl-based procfs support in procfs.c. Given that support for structured procfs was introduced in Solaris 2.6 back in 1997 and we're just removing support for Solaris < 10, there's no point in carrying that baggage (and tons of support for IRIX and OSF/1 as well) around any longer. Most of the patch should be straightforward (removing support for !NEW_PROC_API, non-Solaris OSes and pre-Solaris 10 quirks). Only a few points need explanations: * <sys/syscall.h> was already included unconditionally in most places, so there's no need to have guards in a few remaining ones. * configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so NEW_PROC_API detection for those in configure.ac can go. * I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1. Theoretically, it would be better to include <procfs.h> on Solaris (which includes that define), but that breaks the build over <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux. * I've regenerated syscall_table[] in proc-events.c with a small script from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no traces of older Solaris versions and other OSes left. * prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX doesn't use procfs.c any longer, so all related code can go. The patch was generated with diff -w so one can easier see changes without being distracted by simple reindentations. So far, it has only been compiled and smoke-tested on amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and x86_64-pc-linux-gnu. Certainly needs more testing (Solaris 11.3 vs. 11.4, 32-bit gdb, testsuite once I've figured out what's wrong on Solaris 10 etc.), but it's enough to get a first impression how much cleanup is possible here. * configure.ac Don't check for sys/fault.h, sys/syscall.h, sys/proc.h.

Remove ioctl-based procfs support on Solaris This is the previously mentioned patch to get rid of unstructured/ioctl-based procfs support in procfs.c. Given that support for structured procfs was introduced in Solaris 2.6 back in 1997 and we're just removing support for Solaris < 10, there's no point in carrying that baggage (and tons of support for IRIX and OSF/1 as well) around any longer. Most of the patch should be straightforward (removing support for !NEW_PROC_API, non-Solaris OSes and pre-Solaris 10 quirks). Only a few points need explanations: * <sys/syscall.h> was already included unconditionally in most places, so there's no need to have guards in a few remaining ones. * configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so NEW_PROC_API detection for those in configure.ac can go. * I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1. Theoretically, it would be better to include <procfs.h> on Solaris (which includes that define), but that breaks the build over <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux. * I've regenerated syscall_table[] in proc-events.c with a small script from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no traces of older Solaris versions and other OSes left. * prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX doesn't use procfs.c any longer, so all related code can go. The patch was generated with diff -w so one can easier see changes without being distracted by simple reindentations. So far, it has only been compiled and smoke-tested on amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and x86_64-pc-linux-gnu. Certainly needs more testing (Solaris 11.3 vs. 11.4, 32-bit gdb, testsuite once I've figured out what's wrong on Solaris 10 etc.), but it's enough to get a first impression how much cleanup is possible here. * configure.ac Don't check for sys/fault.h, sys/syscall.h, sys/proc.h.

Only a few points need explanations: * <sys/syscall.h> was already included unconditionally in most places, so there's no need to have guards in a few remaining ones. * configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so NEW_PROC_API detection for those in configure.ac can go. * I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1. Theoretically, it would be better to include <procfs.h> on Solaris (which includes that define), but that breaks the build over <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux. * I've regenerated syscall_table[] in proc-events.c with a small script from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no traces of older Solaris versions and other OSes left. * prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX doesn't use procfs.c any longer, so all related code can go. The patch was generated with diff -w so one can easier see changes without being distracted by simple reindentations. So far, it has only been compiled and smoke-tested on amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and x86_64-pc-linux-gnu. Certainly needs more testing (Solaris 11.3 vs. 11.4, 32-bit gdb, testsuite once I've figured out what's wrong on Solaris 10 etc.), but it's enough to get a first impression how much cleanup is possible here. * configure.ac Don't check for sys/fault.h, sys/syscall.h, sys/proc.h.

Remove ioctl-based procfs support on Solaris This is the previously mentioned patch to get rid of unstructured/ioctl-based procfs support in procfs.c. Given that support for structured procfs was introduced in Solaris 2.6 back in 1997 and we're just removing support for Solaris < 10, there's no point in carrying that baggage (and tons of support for IRIX and OSF/1 as well) around any longer. Most of the patch should be straightforward (removing support for !NEW_PROC_API, non-Solaris OSes and pre-Solaris 10 quirks). Only a few points need explanations: * <sys/syscall.h> was already included unconditionally in most places, so there's no need to have guards in a few remaining ones. * configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so NEW_PROC_API detection for those in configure.ac can go. * I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1. Theoretically, it would be better to include <procfs.h> on Solaris (which includes that define), but that breaks the build over <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux. * I've regenerated syscall_table[] in proc-events.c with a small script from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no traces of older Solaris versions and other OSes left. * prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX doesn't use procfs.c any longer, so all related code can go. The patch was generated with diff -w so one can easier see changes without being distracted by simple reindentations. So far, it has only been compiled and smoke-tested on amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and x86_64-pc-linux-gnu. Certainly needs more testing (Solaris 11.3 vs. 11.4, 32-bit gdb, testsuite once I've figured out what's wrong on Solaris 10 etc.), but it's enough to get a first impression how much cleanup is possible here. * configure.ac Don't check for sys/fault.h, sys/syscall.h, sys/proc.h.

Only a few points need explanations: * <sys/syscall.h> was already included unconditionally in most places, so there's no need to have guards in a few remaining ones. * configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so NEW_PROC_API detection for those in configure.ac can go. * I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1. Theoretically, it would be better to include <procfs.h> on Solaris (which includes that define), but that breaks the build over <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux. * I've regenerated syscall_table[] in proc-events.c with a small script from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no traces of older Solaris versions and other OSes left. * prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX doesn't use procfs.c any longer, so all related code can go. The patch was generated with diff -w so one can easier see changes without being distracted by simple reindentations. So far, it has only been compiled and smoke-tested on amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and x86_64-pc-linux-gnu. Certainly needs more testing (Solaris 11.3 vs. 11.4, 32-bit gdb, testsuite once I've figured out what's wrong on Solaris 10 etc.), but it's enough to get a first impression how much cleanup is possible here. * configure.ac Don't check for sys/fault.h, sys/syscall.h, sys/proc.h.

Replace some xmalloc-family functions with XNEW-family ones This patch is part of the make-gdb-buildable-in-C++ effort. The idea is to change some calls to the xmalloc family of functions to calls to the equivalents in the XNEW family. This avoids adding an explicit cast, so it keeps the code a bit more readable. Some of them also map relatively well to a C++ equivalent (XNEW (struct foo) -> new foo), so it will be possible to do scripted replacements if needed. I only changed calls that were obviously allocating memory for one or multiple "objects". Allocation of variable sizes (such as strings or buffer handling) will be for later (and won't use XNEW). - xmalloc (sizeof (struct foo)) -> XNEW (struct foo) - xmalloc (num * sizeof (struct foo)) -> XNEWVEC (struct foo, num) - xcalloc (1, sizeof (struct foo)) -> XCNEW (struct foo) - xcalloc (num, sizeof (struct foo)) -> XCNEWVEC (struct foo, num) - xrealloc (p, num * sizeof (struct foo) -> XRESIZEVEC (struct foo, p, num) - obstack_alloc (ob, sizeof (struct foo)) -> XOBNEW (ob, struct foo) - obstack_alloc (ob, num * sizeof (struct foo)) -> XOBNEWVEC (ob, struct foo, num) - alloca (sizeof (struct foo)) -> XALLOCA (struct foo) - alloca (num * sizeof (struct foo)) -> XALLOCAVEC (struct foo, num) Some instances of xmalloc followed by memset to zero the buffer were replaced by XCNEW or XCNEWVEC. I regtested on x86-64, Ubuntu 14.04, but the patch touches many architecture-specific files. For those I'll have to rely on the buildbot or people complaining that I broke their gdb. gdb/ChangeLog: * aarch64-linux-nat.c (aarch64_add_process): Likewise. * aarch64-tdep.c (aarch64_gdbarch_init): Likewise. * ada-exp.y (write_ambiguous_var): Likewise. * ada-lang.c (resolve_subexp): Likewise.

Fix gdb C++ compilation on Solaris (PR build/20712) gdb 7.12 doesn't compile as C++ (tried with g++ 4.9) on Solaris (tried 10 and 12, sparc and x86). The following patch (relative to the 7.12 release, though I expect most if not all issues to be present on trunk, too) fixes this. Only a few of the changes bear explanation: * Initially, compilation failed whereever defs.h. was included: In file included from /vol/src/gnu/gdb/gdb-7.12/gdb/gdb.c:19:0: /vol/src/gnu/gdb/gdb-7.12/gdb/defs.h:630:33: error: 'double atof(const char*)' conflicts with a previous declaration extern double atof (const char *); /* X3.159-1989 4.10.1.1 */ ^ In file included from /usr/include/stdlib.h:17:0, from build-gnulib/import/stdlib.h:36, from /vol/src/gnu/gdb/gdb-7.12/gdb/common/common-defs.h:32, from /vol/src/gnu/gdb/gdb-7.12/gdb/defs.h:28, from /vol/src/gnu/gdb/gdb-7.12/gdb/gdb.c:19: /vol/gcc-4.9/lib/gcc/i386-pc-solaris2.10/4.9.0/include-fixed/iso/stdlib_iso.h:119:15: note: previous declaration 'double std::atof(const char*)' extern double atof(const char *); ^ This is due to this gem in gdb/defs.h which seems to have been present like forever: #ifndef atof extern double atof (const char *); /* X3.159-1989 4.10.1.1 */ #endif In the Solaris headers, the appropriate functions are in namespace std, thus the conflict. I've wrapped the defs.h declaration in !__cplusplus to avoid this; perhaps it can go completely instead. * All the casts are necessary to appease g++ and should be pretty obvious. * The sol-thread.c changes are here to handle /vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c: In function 'void _initialize_sol_thread()': /vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c:1252:36: error: invalid conversion from 'void*' to 'void (*)(int)' [-fpermissive] if (!(p_##X = dlsym (dlhandle, #X))) \ ^ /vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c:1255:3: note: in expansion of macro 'resolve' resolve (td_log); ^ and are modeled after linux-thread-db.c (try_thread_db_load_1).

Fix gdb C++ compilation on Solaris (PR build/20712) gdb 7.12 doesn't compile as C++ (tried with g++ 4.9) on Solaris (tried 10 and 12, sparc and x86). The following patch (relative to the 7.12 release, though I expect most if not all issues to be present on trunk, too) fixes this. Only a few of the changes bear explanation: * Initially, compilation failed whereever defs.h. was included: In file included from /vol/src/gnu/gdb/gdb-7.12/gdb/gdb.c:19:0: /vol/src/gnu/gdb/gdb-7.12/gdb/defs.h:630:33: error: 'double atof(const char*)' conflicts with a previous declaration extern double atof (const char *); /* X3.159-1989 4.10.1.1 */ ^ In file included from /usr/include/stdlib.h:17:0, from build-gnulib/import/stdlib.h:36, from /vol/src/gnu/gdb/gdb-7.12/gdb/common/common-defs.h:32, from /vol/src/gnu/gdb/gdb-7.12/gdb/defs.h:28, from /vol/src/gnu/gdb/gdb-7.12/gdb/gdb.c:19: /vol/gcc-4.9/lib/gcc/i386-pc-solaris2.10/4.9.0/include-fixed/iso/stdlib_iso.h:119:15: note: previous declaration 'double std::atof(const char*)' extern double atof(const char *); ^ This is due to this gem in gdb/defs.h which seems to have been present like forever: #ifndef atof extern double atof (const char *); /* X3.159-1989 4.10.1.1 */ #endif In the Solaris headers, the appropriate functions are in namespace std, thus the conflict. I've wrapped the defs.h declaration in !__cplusplus to avoid this; perhaps it can go completely instead. * All the casts are necessary to appease g++ and should be pretty obvious. * The sol-thread.c changes are here to handle /vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c: In function 'void _initialize_sol_thread()': /vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c:1252:36: error: invalid conversion from 'void*' to 'void (*)(int)' [-fpermissive] if (!(p_##X = dlsym (dlhandle, #X))) \ ^ /vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c:1255:3: note: in expansion of macro 'resolve' resolve (td_log); ^ and are modeled after linux-thread-db.c (try_thread_db_load_1).

Remove ioctl-based procfs support on Solaris This is the previously mentioned patch to get rid of unstructured/ioctl-based procfs support in procfs.c. Given that support for structured procfs was introduced in Solaris 2.6 back in 1997 and we're just removing support for Solaris < 10, there's no point in carrying that baggage (and tons of support for IRIX and OSF/1 as well) around any longer. Most of the patch should be straightforward (removing support for !NEW_PROC_API, non-Solaris OSes and pre-Solaris 10 quirks). Only a few points need explanations: * <sys/syscall.h> was already included unconditionally in most places, so there's no need to have guards in a few remaining ones. * configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so NEW_PROC_API detection for those in configure.ac can go. * I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1. Theoretically, it would be better to include <procfs.h> on Solaris (which includes that define), but that breaks the build over <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux. * I've regenerated syscall_table[] in proc-events.c with a small script from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no traces of older Solaris versions and other OSes left. * prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX doesn't use procfs.c any longer, so all related code can go. The patch was generated with diff -w so one can easier see changes without being distracted by simple reindentations. So far, it has only been compiled and smoke-tested on amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and x86_64-pc-linux-gnu. Certainly needs more testing (Solaris 11.3 vs. 11.4, 32-bit gdb, testsuite once I've figured out what's wrong on Solaris 10 etc.), but it's enough to get a first impression how much cleanup is possible here. * configure.ac Don't check for sys/fault.h, sys/syscall.h, sys/proc.h.

Only a few points need explanations: * <sys/syscall.h> was already included unconditionally in most places, so there's no need to have guards in a few remaining ones. * configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so NEW_PROC_API detection for those in configure.ac can go. * I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1. Theoretically, it would be better to include <procfs.h> on Solaris (which includes that define), but that breaks the build over <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux. * I've regenerated syscall_table[] in proc-events.c with a small script from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no traces of older Solaris versions and other OSes left. * prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX doesn't use procfs.c any longer, so all related code can go. The patch was generated with diff -w so one can easier see changes without being distracted by simple reindentations. So far, it has only been compiled and smoke-tested on amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and x86_64-pc-linux-gnu. Certainly needs more testing (Solaris 11.3 vs. 11.4, 32-bit gdb, testsuite once I've figured out what's wrong on Solaris 10 etc.), but it's enough to get a first impression how much cleanup is possible here. * configure.ac Don't check for sys/fault.h, sys/syscall.h, sys/proc.h.

Fix gdb C++ compilation on Solaris (PR build/20712) gdb 7.12 doesn't compile as C++ (tried with g++ 4.9) on Solaris (tried 10 and 12, sparc and x86). The following patch (relative to the 7.12 release, though I expect most if not all issues to be present on trunk, too) fixes this. Only a few of the changes bear explanation: * Initially, compilation failed whereever defs.h. was included: In file included from /vol/src/gnu/gdb/gdb-7.12/gdb/gdb.c:19:0: /vol/src/gnu/gdb/gdb-7.12/gdb/defs.h:630:33: error: 'double atof(const char*)' conflicts with a previous declaration extern double atof (const char *); /* X3.159-1989 4.10.1.1 */ ^ In file included from /usr/include/stdlib.h:17:0, from build-gnulib/import/stdlib.h:36, from /vol/src/gnu/gdb/gdb-7.12/gdb/common/common-defs.h:32, from /vol/src/gnu/gdb/gdb-7.12/gdb/defs.h:28, from /vol/src/gnu/gdb/gdb-7.12/gdb/gdb.c:19: /vol/gcc-4.9/lib/gcc/i386-pc-solaris2.10/4.9.0/include-fixed/iso/stdlib_iso.h:119:15: note: previous declaration 'double std::atof(const char*)' extern double atof(const char *); ^ This is due to this gem in gdb/defs.h which seems to have been present like forever: #ifndef atof extern double atof (const char *); /* X3.159-1989 4.10.1.1 */ #endif In the Solaris headers, the appropriate functions are in namespace std, thus the conflict. I've wrapped the defs.h declaration in !__cplusplus to avoid this; perhaps it can go completely instead. * All the casts are necessary to appease g++ and should be pretty obvious. * The sol-thread.c changes are here to handle /vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c: In function 'void _initialize_sol_thread()': /vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c:1252:36: error: invalid conversion from 'void*' to 'void (*)(int)' [-fpermissive] if (!(p_##X = dlsym (dlhandle, #X))) \ ^ /vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c:1255:3: note: in expansion of macro 'resolve' resolve (td_log); ^ and are modeled after linux-thread-db.c (try_thread_db_load_1). The patch allowed both 32 and 64-bit C++ builds on sparc-sun-solaris2.10 and i386-pc-solaris2.10 to complete. The resulting binary hasn't seen more than a smoke test (invoke it on itself, b main, run) yet. When investigating the failure to detect -static-libstdc++ support (more below), I found two more issues which only show up with -Werror: /vol/src/gnu/gdb/gdb/local/gdb/procfs.c: In function 'ssd* proc_get_LDT_entry(procinfo*, int)': /vol/src/gnu/gdb/gdb/local/gdb/procfs.c:2487:19: error: variable 'old_chain' set but not used [-Werror=unused-but-set-variable] struct cleanup *old_chain = NULL; ^ Unless I'm mistaken, you need to run do_cleanups on every return from the function.

Remove ioctl-based procfs support on Solaris This is the previously mentioned patch to get rid of unstructured/ioctl-based procfs support in procfs.c. Given that support for structured procfs was introduced in Solaris 2.6 back in 1997 and we're just removing support for Solaris < 10, there's no point in carrying that baggage (and tons of support for IRIX and OSF/1 as well) around any longer. Most of the patch should be straightforward (removing support for !NEW_PROC_API, non-Solaris OSes and pre-Solaris 10 quirks). Only a few points need explanations: * <sys/syscall.h> was already included unconditionally in most places, so there's no need to have guards in a few remaining ones. * configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so NEW_PROC_API detection for those in configure.ac can go. * I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1. Theoretically, it would be better to include <procfs.h> on Solaris (which includes that define), but that breaks the build over <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux. * I've regenerated syscall_table[] in proc-events.c with a small script from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no traces of older Solaris versions and other OSes left. * prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX doesn't use procfs.c any longer, so all related code can go. The patch was generated with diff -w so one can easier see changes without being distracted by simple reindentations. So far, it has only been compiled and smoke-tested on amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and x86_64-pc-linux-gnu.

Remove ioctl-based procfs support on Solaris This is the previously mentioned patch to get rid of unstructured/ioctl-based procfs support in procfs.c. Given that support for structured procfs was introduced in Solaris 2.6 back in 1997 and we're just removing support for Solaris < 10, there's no point in carrying that baggage (and tons of support for IRIX and OSF/1 as well) around any longer. Most of the patch should be straightforward (removing support for !NEW_PROC_API, non-Solaris OSes and pre-Solaris 10 quirks). Only a few points need explanations: * <sys/syscall.h> was already included unconditionally in most places, so there's no need to have guards in a few remaining ones. * configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so NEW_PROC_API detection for those in configure.ac can go. * I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1. Theoretically, it would be better to include <procfs.h> on Solaris (which includes that define), but that breaks the build over <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux. * I've regenerated syscall_table[] in proc-events.c with a small script from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no traces of older Solaris versions and other OSes left. * prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX doesn't use procfs.c any longer, so all related code can go.

Allow making GDB not automatically connect to the native target. Sometimes it's useful to be able to disable the automatic connection to the native target. E.g., sometimes GDB disconnects from the extended-remote target I was debugging, without me noticing it, and then I do "run". That starts the program locally, and only after a little head scratch session do I figure out the program is running locally instead of remotely as intended. Same thing with "attach", "info os", etc. With the patch, we now can have this instead: (gdb) set auto-connect-native-target off (gdb) target extended-remote :9999 ... *gdb disconnects* (gdb) run Don't know how to run. Try "help target". To still be able to connect to the native target with auto-connect-native-target set to off, I've made "target native" work instead of erroring out as today. Before: (gdb) target native Use the "run" command to start a native process. After: (gdb) target native Done. Use the "run" command to start a process. (gdb) maint print target-stack The current target stack is: - native (Native process) - exec (Local exec file) - None (None) (gdb) run Starting program: ./a.out ... I've also wanted this for the testsuite, when running against the native-extended-gdbserver.exp board (runs against gdbserver in extended-remote mode). With a non-native-target board, it's always a bug to launch a program with the native target. Turns out we still have one such case this patch catches: (gdb) break main Breakpoint 1 at 0x4009e5: file ../../../src/gdb/testsuite/gdb.base/coremaker.c, line 138. (gdb) run Don't know how to run. Try "help target". (gdb) FAIL: gdb.base/corefile.exp: run: with core On the patch itself, probably the least obvious bit is the need to go through all targets, and move the unpush_target call to after the generic_mourn_inferior call instead of before. This is what inf-ptrace.c does too, ever since multi-process support was added. The reason inf-ptrace.c does things in that order is that in the current multi-process/single-target model, we shouldn't unpush the target if there are still other live inferiors being debugged. The check for that is "have_inferiors ()" (a misnomer nowadays...), which does: have_inferiors (void) { for (inf = inferior_list; inf; inf = inf->next) if (inf->pid != 0) return 1; It's generic_mourn_inferior that ends up clearing inf->pid, so we need to call it before the have_inferiors check. To make all native targets behave the same WRT to explicit "target native", I've added an inf_child_maybe_unpush_target function that targets call instead of calling unpush_target directly, and as that includes the have_inferiors check, I needed to adjust the targets. Tested on x86_64 Fedora 20, native, and also with the extended-gdbserver board. Confirmed a cross build of djgpp gdb still builds. Smoke tested a cross build of Windows gdb under Wine.

constify to_detach This patch constifies the target_ops method to_detach. This is a small cleanup, but also, I think, a bug-prevention fix, since gdb already acts as if the "args" argument here was const. In particular, top.c:quit_force calls kill_or_detach via iterate_over_inferiors. kill_or_detach calls target_detach, passing the same argument each time. So, if one of these methods was not const-correct, then kill_or_detach would change its behavior in a strange way. I could not build every target I modified in this patch. I've inspected them all by hand, though. Many targets do not use the "args" parameter; a couple pass it to atoi; and a few pass it on to the to_detach method of the target beneath. The only code that required a real change was in linux-nat.c, and that only needed the introduction of a temporary variable for const-correctness. 2013-11-08 Tom Tromey <tromey@redhat.com> * aix-thread.c (aix_thread_detach): Update. * corelow.c (core_detach): Update. * darwin-nat.c (darwin_detach): Update. * dec-thread.c (dec_thread_detach): Update. * gnu-nat.c (gnu_detach): Update. * go32-nat.c (go32_detach): Update. * inf-ptrace.c (inf_ptrace_detach): Update. * inf-ttrace.c (inf_ttrace_detach): Update. * linux-fork.c (linux_fork_detach): Update. * linux-fork.h (linux_fork_detach): Update. * linux-nat.c (linux_nat_detach): Update.

detach_inferior (pid);
Allow making GDB not automatically connect to the native target. Sometimes it's useful to be able to disable the automatic connection to the native target. E.g., sometimes GDB disconnects from the extended-remote target I was debugging, without me noticing it, and then I do "run". That starts the program locally, and only after a little head scratch session do I figure out the program is running locally instead of remotely as intended. Same thing with "attach", "info os", etc. With the patch, we now can have this instead: (gdb) set auto-connect-native-target off (gdb) target extended-remote :9999 ... *gdb disconnects* (gdb) run Don't know how to run. Try "help target". To still be able to connect to the native target with auto-connect-native-target set to off, I've made "target native" work instead of erroring out as today. Before: (gdb) target native Use the "run" command to start a native process. After: (gdb) target native Done. Use the "run" command to start a process. (gdb) maint print target-stack The current target stack is: - native (Native process) - exec (Local exec file) - None (None) (gdb) run Starting program: ./a.out ... I've also wanted this for the testsuite, when running against the native-extended-gdbserver.exp board (runs against gdbserver in extended-remote mode). With a non-native-target board, it's always a bug to launch a program with the native target. Turns out we still have one such case this patch catches: (gdb) break main Breakpoint 1 at 0x4009e5: file ../../../src/gdb/testsuite/gdb.base/coremaker.c, line 138. (gdb) run Don't know how to run. Try "help target". (gdb) FAIL: gdb.base/corefile.exp: run: with core On the patch itself, probably the least obvious bit is the need to go through all targets, and move the unpush_target call to after the generic_mourn_inferior call instead of before. This is what inf-ptrace.c does too, ever since multi-process support was added. The reason inf-ptrace.c does things in that order is that in the current multi-process/single-target model, we shouldn't unpush the target if there are still other live inferiors being debugged. The check for that is "have_inferiors ()" (a misnomer nowadays...), which does: have_inferiors (void) { for (inf = inferior_list; inf; inf = inf->next) if (inf->pid != 0) return 1; It's generic_mourn_inferior that ends up clearing inf->pid, so we need to call it before the have_inferiors check. To make all native targets behave the same WRT to explicit "target native", I've added an inf_child_maybe_unpush_target function that targets call instead of calling unpush_target directly, and as that includes the have_inferiors check, I needed to adjust the targets. Tested on x86_64 Fedora 20, native, and also with the extended-gdbserver board. Confirmed a cross build of djgpp gdb still builds. Smoke tested a cross build of Windows gdb under Wine.

/* Fetch register REGNUM from the inferior. If REGNUM is -1, do this
for all registers.
??? Is the following note still relevant? We can't get individual
registers with the PT_GETREGS ptrace(2) request either, yet we
don't bother with caching at all in that case.
NOTE: Since the /proc interface cannot give us individual
registers, we pay no attention to REGNUM, and just fetch them all.
This results in the possibility that we will do unnecessarily many
fetches, since we may be called repeatedly for individual
registers. So we cache the results, and mark the cache invalid
when the process is resumed. */

s/get_regcache_arch (regcache)/regcache->arch ()/g This patches removes get_regcache_arch, and use regache->arch () instead. The motivation of this change is that I am going to move some basic stuff into a base class of regcache. I don't need to update "client" code regcache->arch ().

Remove ioctl-based procfs support on Solaris This is the previously mentioned patch to get rid of unstructured/ioctl-based procfs support in procfs.c. Given that support for structured procfs was introduced in Solaris 2.6 back in 1997 and we're just removing support for Solaris < 10, there's no point in carrying that baggage (and tons of support for IRIX and OSF/1 as well) around any longer. Most of the patch should be straightforward (removing support for !NEW_PROC_API, non-Solaris OSes and pre-Solaris 10 quirks). Only a few points need explanations: * <sys/syscall.h> was already included unconditionally in most places, so there's no need to have guards in a few remaining ones. * configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so NEW_PROC_API detection for those in configure.ac can go. * I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1. Theoretically, it would be better to include <procfs.h> on Solaris (which includes that define), but that breaks the build over <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux. * I've regenerated syscall_table[] in proc-events.c with a small script from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no traces of older Solaris versions and other OSes left. * prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX doesn't use procfs.c any longer, so all related code can go. The patch was generated with diff -w so one can easier see changes without being distracted by simple reindentations. So far, it has only been compiled and smoke-tested on amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and x86_64-pc-linux-gnu. Certainly needs more testing (Solaris 11.3 vs. 11.4, 32-bit gdb, testsuite once I've figured out what's wrong on Solaris 10 etc.), but it's enough to get a first impression how much cleanup is possible here. * configure.ac Don't check for sys/fault.h, sys/syscall.h, sys/proc.h. (NEW_PROC_API): Remove. (prsysent_t, pr_sigset_t, pr_sigaction64_t, pr_siginfo64_t): Likewise. * common/common.m4 (GDB_AC_COMMON): Don't check for sys/syscall.h. * configure: Regenerate. * config.in: Regenerate. * gdbserver/configure: Regenerate. * gdbserver/config.in: Regenerate. * i386-sol2-nat.c (_initialize_amd64_sol2_nat): Remove NEW_PROC_API test. * sparc-sol2-nat.c (_initialize_sparc_sol2_nat): Likewise. * linux-btrace.c: Remove HAVE_SYS_SYSCALL_H test. * proc-api.c: Remove !NEW_PROC_API support.

I've wrapped the defs.h declaration in !__cplusplus to avoid this; perhaps it can go completely instead. * All the casts are necessary to appease g++ and should be pretty obvious. * The sol-thread.c changes are here to handle /vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c: In function 'void _initialize_sol_thread()': /vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c:1252:36: error: invalid conversion from 'void*' to 'void (*)(int)' [-fpermissive] if (!(p_##X = dlsym (dlhandle, #X))) \ ^ /vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c:1255:3: note: in expansion of macro 'resolve' resolve (td_log); ^ and are modeled after linux-thread-db.c (try_thread_db_load_1). The patch allowed both 32 and 64-bit C++ builds on sparc-sun-solaris2.10 and i386-pc-solaris2.10 to complete. The resulting binary hasn't seen more than a smoke test (invoke it on itself, b main, run) yet. When investigating the failure to detect -static-libstdc++ support (more below), I found two more issues which only show up with -Werror: /vol/src/gnu/gdb/gdb/local/gdb/procfs.c: In function 'ssd* proc_get_LDT_entry(procinfo*, int)': /vol/src/gnu/gdb/gdb/local/gdb/procfs.c:2487:19: error: variable 'old_chain' set but not used [-Werror=unused-but-set-variable] struct cleanup *old_chain = NULL; ^ Unless I'm mistaken, you need to run do_cleanups on every return from the function. Afterwards, I ran a 32-bit compilation, which (after adding --disable-largefile to avoid In file included from /usr/include/sys/procfs.h:28:0, from /vol/src/gnu/gdb/gdb/local/gdb/i386-sol2-nat.c:23: /usr/include/sys/old_procfs.h:39:2: error: #error "Cannot use procfs in the large file compilation environment" #error "Cannot use procfs in the large file compilation environment" ^ and two more instances) revealed /vol/src/gnu/gdb/gdb/local/gdb/top.c: In function 'void gdb_safe_append_history()': /vol/src/gnu/gdb/gdb/local/gdb/top.c:1170:59: error: format '%d' expects argument of type 'int', but argument 3 has type 'pid_t {aka long int}' [-Werror=format=] = xstrprintf ("%s-gdb%d~", history_filename, getpid ()); ^ Fixed by casting pid_t to long and printing it as such.

Return target_xfer_status in to_xfer_partial This patch does the conversion of to_xfer_partial from LONGEST (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len); to enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops, enum target_object object, const char *annex, gdb_byte *readbuf, const gdb_byte *writebuf, ULONGEST offset, ULONGEST len, ULONGEST *xfered_len); It changes to_xfer_partial return the transfer status and the transfered length by *XFERED_LEN. Generally, the return status has three stats, - TARGET_XFER_OK, - TARGET_XFER_EOF, - TARGET_XFER_E_XXXX, See the comments to them in 'enum target_xfer_status'. Note that Pedro suggested not name TARGET_XFER_DONE, as it is confusing, compared with "TARGET_XFER_OK". We finally name it TARGET_XFER_EOF. With this change, GDB core can handle unavailable data in a convenient way. The rationale behind this change was mentioned here https://sourceware.org/ml/gdb-patches/2013-10/msg00761.html Consider an object/value like this: 0 100 150 200 512 DDDDDDDDDDDxxxxxxxxxDDDDDD...DDIIIIIIIIIIII..III where D is valid data, and xxx is unavailable data, and I is beyond the end of the object (Invalid). Currently, if we start the xfer at 0, requesting, say 512 bytes, we'll first get back 100 bytes. The xfer machinery then retries fetching [100,512), and gets back TARGET_XFER_E_UNAVAILABLE. That's sufficient when you're either interested in either having the whole of the 512 bytes available, or erroring out. But, in this scenario, we're interested in the data at [150,512). The problem is that the last TARGET_XFER_E_UNAVAILABLE gives us no indication where to start the read next. We'd need something like: get me [0,512) >>> <<< here's [0,100), *xfered_len is 100, returns TARGET_XFER_OK get me [100,512) >>> (**1) <<< [100,150) is unavailable, *xfered_len is 50, return TARGET_XFER_E_UNAVAILABLE. get me [150,512) >>> <<< here's [150,200), *xfered_len is 50, return TARGET_XFER_OK. get me [200,512) >>> <<< no more data, return TARGET_XFER_EOF. This naturally implies pushing down the decision of whether to return TARGET_XFER_E_UNAVAILABLE or something else down to the target. (Which kinds of leads back to tfile itself reading from RO memory from file (though we could export a function in exec.c for that that tfile delegates to, instead of re-adding the old code). Beside this change, we also add a macro TARGET_XFER_STATUS_ERROR_P to check whether a status is an error or not, to stop using "status < 0". This patch also eliminates the comparison between status and 0. No target implementations to to_xfer_partial adapts this new interface.

Remove ioctl-based procfs support on Solaris This is the previously mentioned patch to get rid of unstructured/ioctl-based procfs support in procfs.c. Given that support for structured procfs was introduced in Solaris 2.6 back in 1997 and we're just removing support for Solaris < 10, there's no point in carrying that baggage (and tons of support for IRIX and OSF/1 as well) around any longer. Most of the patch should be straightforward (removing support for !NEW_PROC_API, non-Solaris OSes and pre-Solaris 10 quirks). Only a few points need explanations: * <sys/syscall.h> was already included unconditionally in most places, so there's no need to have guards in a few remaining ones. * configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so NEW_PROC_API detection for those in configure.ac can go. * I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1. Theoretically, it would be better to include <procfs.h> on Solaris (which includes that define), but that breaks the build over <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux. * I've regenerated syscall_table[] in proc-events.c with a small script from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no traces of older Solaris versions and other OSes left. * prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX doesn't use procfs.c any longer, so all related code can go. The patch was generated with diff -w so one can easier see changes without being distracted by simple reindentations. So far, it has only been compiled and smoke-tested on amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and x86_64-pc-linux-gnu. Certainly needs more testing (Solaris 11.3 vs. 11.4, 32-bit gdb, testsuite once I've figured out what's wrong on Solaris 10 etc.), but it's enough to get a first impression how much cleanup is possible here. * configure.ac Don't check for sys/fault.h, sys/syscall.h, sys/proc.h.

The issue is that we don't currently distinguish send "interrupt/ctrl-c" to target terminal vs "stop/pause" thread well; both cases go through "target_stop". And then, the native Linux backend (linux-nat.c) implements target_stop with SIGSTOP in non-stop mode, and SIGINT in all-stop mode. Since "maint set target-non-stop on" forces the backend to be always running in non-stop mode, even though the user-visible behavior is "set non-stop" is "off", "interrupt" causes a SIGSTOP instead of the SIGINT the test expects. Fix this by introducing a target_interrupt method to use in the "interrupt/ctrl-c" case, so "set non-stop off" can always work the same irrespective of "maint set target-non-stop on/off". I'm explictly considering changing the "set non-stop on" behavior as out of scope here. Most of the patch is an across-the-board rename of to_stop hook implementations to to_interrupt. The only targets where something more than a rename is being done are linux-nat.c and remote.c, which are the only targets that support async, and thus are the only ones the core side calls target_stop on. gdb/ChangeLog: 2015-08-07 Pedro Alves <palves@redhat.com> * darwin-nat.c (darwin_stop): Rename to ...

Consolidate target_mourn_inferior between GDB and gdbserver This patch consolidates the API of target_mourn_inferior between GDB and gdbserver, in my continuing efforts to make sharing the fork_inferior function possible between both. GDB's version of the function did not care about the inferior's ptid being mourned, but gdbserver's needed to know this information. Since it actually makes sense to pass the ptid as an argument, instead of depending on a global value directly (which GDB's version did), I decided to make the generic API to accept it. I then went on and extended all calls being made on GDB to include a ptid argument (which ended up being inferior_ptid most of the times, anyway), and now we have a more sane interface. On GDB's side, after talking to Pedro a bit about it, we decided that just an assertion to make sure that the ptid being passed is equal to inferior_ptid would be enough for now, on the GDB side. We can remove the assertion and perform more operations later if we ever pass anything different than inferior_ptid. Regression tested on our BuildBot, everything OK. I'd appreciate a special look at gdb/windows-nat.c's modification because I wasn't really sure what to do there. It seemed to me that maybe I should build a ptid out of the process information there, but then I am almost sure the assertion on GDB's side would trigger. gdb/ChangeLog: 2016-09-19 Sergio Durigan Junior <sergiodj@redhat.com> * darwin-nat.c (darwin_kill_inferior): Adjusting call to target_mourn_inferior to include ptid_t argument. * fork-child.c (startup_inferior): Likewise. * gnu-nat.c (gnu_kill_inferior): Likewise. * inf-ptrace.c (inf_ptrace_kill): Likewise. * infrun.c (handle_inferior_event_1): Likewise. * linux-nat.c (linux_nat_attach): Likewise.

Allow making GDB not automatically connect to the native target. Sometimes it's useful to be able to disable the automatic connection to the native target. E.g., sometimes GDB disconnects from the extended-remote target I was debugging, without me noticing it, and then I do "run". That starts the program locally, and only after a little head scratch session do I figure out the program is running locally instead of remotely as intended. Same thing with "attach", "info os", etc. With the patch, we now can have this instead: (gdb) set auto-connect-native-target off (gdb) target extended-remote :9999 ... *gdb disconnects* (gdb) run Don't know how to run. Try "help target". To still be able to connect to the native target with auto-connect-native-target set to off, I've made "target native" work instead of erroring out as today. Before: (gdb) target native Use the "run" command to start a native process. After: (gdb) target native Done. Use the "run" command to start a process. (gdb) maint print target-stack The current target stack is: - native (Native process) - exec (Local exec file) - None (None) (gdb) run Starting program: ./a.out ... I've also wanted this for the testsuite, when running against the native-extended-gdbserver.exp board (runs against gdbserver in extended-remote mode). With a non-native-target board, it's always a bug to launch a program with the native target. Turns out we still have one such case this patch catches: (gdb) break main Breakpoint 1 at 0x4009e5: file ../../../src/gdb/testsuite/gdb.base/coremaker.c, line 138. (gdb) run Don't know how to run. Try "help target". (gdb) FAIL: gdb.base/corefile.exp: run: with core On the patch itself, probably the least obvious bit is the need to go through all targets, and move the unpush_target call to after the generic_mourn_inferior call instead of before. This is what inf-ptrace.c does too, ever since multi-process support was added. The reason inf-ptrace.c does things in that order is that in the current multi-process/single-target model, we shouldn't unpush the target if there are still other live inferiors being debugged. The check for that is "have_inferiors ()" (a misnomer nowadays...), which does: have_inferiors (void) { for (inf = inferior_list; inf; inf = inf->next) if (inf->pid != 0) return 1; It's generic_mourn_inferior that ends up clearing inf->pid, so we need to call it before the have_inferiors check. To make all native targets behave the same WRT to explicit "target native", I've added an inf_child_maybe_unpush_target function that targets call instead of calling unpush_target directly, and as that includes the have_inferiors check, I needed to adjust the targets. Tested on x86_64 Fedora 20, native, and also with the extended-gdbserver board. Confirmed a cross build of djgpp gdb still builds. Smoke tested a cross build of Windows gdb under Wine.

Allow making GDB not automatically connect to the native target. Sometimes it's useful to be able to disable the automatic connection to the native target. E.g., sometimes GDB disconnects from the extended-remote target I was debugging, without me noticing it, and then I do "run". That starts the program locally, and only after a little head scratch session do I figure out the program is running locally instead of remotely as intended. Same thing with "attach", "info os", etc. With the patch, we now can have this instead: (gdb) set auto-connect-native-target off (gdb) target extended-remote :9999 ... *gdb disconnects* (gdb) run Don't know how to run. Try "help target". To still be able to connect to the native target with auto-connect-native-target set to off, I've made "target native" work instead of erroring out as today. Before: (gdb) target native Use the "run" command to start a native process. After: (gdb) target native Done. Use the "run" command to start a process. (gdb) maint print target-stack The current target stack is: - native (Native process) - exec (Local exec file) - None (None) (gdb) run Starting program: ./a.out ... I've also wanted this for the testsuite, when running against the native-extended-gdbserver.exp board (runs against gdbserver in extended-remote mode). With a non-native-target board, it's always a bug to launch a program with the native target. Turns out we still have one such case this patch catches: (gdb) break main Breakpoint 1 at 0x4009e5: file ../../../src/gdb/testsuite/gdb.base/coremaker.c, line 138. (gdb) run Don't know how to run. Try "help target". (gdb) FAIL: gdb.base/corefile.exp: run: with core On the patch itself, probably the least obvious bit is the need to go through all targets, and move the unpush_target call to after the generic_mourn_inferior call instead of before. This is what inf-ptrace.c does too, ever since multi-process support was added. The reason inf-ptrace.c does things in that order is that in the current multi-process/single-target model, we shouldn't unpush the target if there are still other live inferiors being debugged. The check for that is "have_inferiors ()" (a misnomer nowadays...), which does: have_inferiors (void) { for (inf = inferior_list; inf; inf = inf->next) if (inf->pid != 0) return 1; It's generic_mourn_inferior that ends up clearing inf->pid, so we need to call it before the have_inferiors check. To make all native targets behave the same WRT to explicit "target native", I've added an inf_child_maybe_unpush_target function that targets call instead of calling unpush_target directly, and as that includes the have_inferiors check, I needed to adjust the targets. Tested on x86_64 Fedora 20, native, and also with the extended-gdbserver board. Confirmed a cross build of djgpp gdb still builds. Smoke tested a cross build of Windows gdb under Wine.

Remove ioctl-based procfs support on Solaris This is the previously mentioned patch to get rid of unstructured/ioctl-based procfs support in procfs.c. Given that support for structured procfs was introduced in Solaris 2.6 back in 1997 and we're just removing support for Solaris < 10, there's no point in carrying that baggage (and tons of support for IRIX and OSF/1 as well) around any longer. Most of the patch should be straightforward (removing support for !NEW_PROC_API, non-Solaris OSes and pre-Solaris 10 quirks). Only a few points need explanations: * <sys/syscall.h> was already included unconditionally in most places, so there's no need to have guards in a few remaining ones. * configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so NEW_PROC_API detection for those in configure.ac can go. * I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1. Theoretically, it would be better to include <procfs.h> on Solaris (which includes that define), but that breaks the build over <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux. * I've regenerated syscall_table[] in proc-events.c with a small script from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no traces of older Solaris versions and other OSes left. * prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX doesn't use procfs.c any longer, so all related code can go. The patch was generated with diff -w so one can easier see changes without being distracted by simple reindentations. So far, it has only been compiled and smoke-tested on amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and x86_64-pc-linux-gnu. Certainly needs more testing (Solaris 11.3 vs. 11.4, 32-bit gdb, testsuite once I've figured out what's wrong on Solaris 10 etc.), but it's enough to get a first impression how much cleanup is possible here. * configure.ac Don't check for sys/fault.h, sys/syscall.h, sys/proc.h. (NEW_PROC_API): Remove. (prsysent_t, pr_sigset_t, pr_sigaction64_t, pr_siginfo64_t): Likewise. * common/common.m4 (GDB_AC_COMMON): Don't check for sys/syscall.h. * configure: Regenerate. * config.in: Regenerate. * gdbserver/configure: Regenerate. * gdbserver/config.in: Regenerate. * i386-sol2-nat.c (_initialize_amd64_sol2_nat): Remove NEW_PROC_API test. * sparc-sol2-nat.c (_initialize_sparc_sol2_nat): Likewise. * linux-btrace.c: Remove HAVE_SYS_SYSCALL_H test. * proc-api.c: Remove !NEW_PROC_API support.

/* This routine called on the parent side (GDB side)
after GDB forks the inferior. */
Allow making GDB not automatically connect to the native target. Sometimes it's useful to be able to disable the automatic connection to the native target. E.g., sometimes GDB disconnects from the extended-remote target I was debugging, without me noticing it, and then I do "run". That starts the program locally, and only after a little head scratch session do I figure out the program is running locally instead of remotely as intended. Same thing with "attach", "info os", etc. With the patch, we now can have this instead: (gdb) set auto-connect-native-target off (gdb) target extended-remote :9999 ... *gdb disconnects* (gdb) run Don't know how to run. Try "help target". To still be able to connect to the native target with auto-connect-native-target set to off, I've made "target native" work instead of erroring out as today. Before: (gdb) target native Use the "run" command to start a native process. After: (gdb) target native Done. Use the "run" command to start a process. (gdb) maint print target-stack The current target stack is: - native (Native process) - exec (Local exec file) - None (None) (gdb) run Starting program: ./a.out ... I've also wanted this for the testsuite, when running against the native-extended-gdbserver.exp board (runs against gdbserver in extended-remote mode). With a non-native-target board, it's always a bug to launch a program with the native target. Turns out we still have one such case this patch catches: (gdb) break main Breakpoint 1 at 0x4009e5: file ../../../src/gdb/testsuite/gdb.base/coremaker.c, line 138. (gdb) run Don't know how to run. Try "help target". (gdb) FAIL: gdb.base/corefile.exp: run: with core On the patch itself, probably the least obvious bit is the need to go through all targets, and move the unpush_target call to after the generic_mourn_inferior call instead of before. This is what inf-ptrace.c does too, ever since multi-process support was added. The reason inf-ptrace.c does things in that order is that in the current multi-process/single-target model, we shouldn't unpush the target if there are still other live inferiors being debugged. The check for that is "have_inferiors ()" (a misnomer nowadays...), which does: have_inferiors (void) { for (inf = inferior_list; inf; inf = inf->next) if (inf->pid != 0) return 1; It's generic_mourn_inferior that ends up clearing inf->pid, so we need to call it before the have_inferiors check. To make all native targets behave the same WRT to explicit "target native", I've added an inf_child_maybe_unpush_target function that targets call instead of calling unpush_target directly, and as that includes the have_inferiors check, I needed to adjust the targets. Tested on x86_64 Fedora 20, native, and also with the extended-gdbserver board. Confirmed a cross build of djgpp gdb still builds. Smoke tested a cross build of Windows gdb under Wine.

Share fork_inferior et al with gdbserver This is the most important (and the biggest, sorry) patch of the series. It moves fork_inferior from gdb/fork-child.c to nat/fork-inferior.c and makes all the necessary adjustments to both GDB and gdbserver to make sure everything works OK. There is no "most important change" with this patch; all changes are made in a progressive way, making sure that gdbserver had the necessary features while not breaking GDB at the same time. I decided to go ahead and implement a partial support for starting the inferior with a shell on gdbserver, although the full feature comes in the next patch. The user won't have the option to disable the startup-with-shell, and also won't be able to change which shell gdbserver will use (other than setting the $SHELL environment variable, that is). Everything is working as expected, and no regressions were present during the tests. gdb/ChangeLog: 2017-06-07 Sergio Durigan Junior <sergiodj@redhat.com> Pedro Alves <palves@redhat.com> * Makefile.in (HFILES_NO_SRCDIR): Add "common/common-inferior.h" and "nat/fork-inferior.h". * common/common-inferior.h: New file, with contents from "gdb/inferior.h". * commom/common-utils.c: Include "common-utils.h".

Remove ioctl-based procfs support on Solaris This is the previously mentioned patch to get rid of unstructured/ioctl-based procfs support in procfs.c. Given that support for structured procfs was introduced in Solaris 2.6 back in 1997 and we're just removing support for Solaris < 10, there's no point in carrying that baggage (and tons of support for IRIX and OSF/1 as well) around any longer. Most of the patch should be straightforward (removing support for !NEW_PROC_API, non-Solaris OSes and pre-Solaris 10 quirks). Only a few points need explanations: * <sys/syscall.h> was already included unconditionally in most places, so there's no need to have guards in a few remaining ones. * configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so NEW_PROC_API detection for those in configure.ac can go. * I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1. Theoretically, it would be better to include <procfs.h> on Solaris (which includes that define), but that breaks the build over <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux. * I've regenerated syscall_table[] in proc-events.c with a small script from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no traces of older Solaris versions and other OSes left. * prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX doesn't use procfs.c any longer, so all related code can go. The patch was generated with diff -w so one can easier see changes without being distracted by simple reindentations. So far, it has only been compiled and smoke-tested on amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and x86_64-pc-linux-gnu. Certainly needs more testing (Solaris 11.3 vs. 11.4, 32-bit gdb, testsuite once I've figured out what's wrong on Solaris 10 etc.), but it's enough to get a first impression how much cleanup is possible here. * configure.ac Don't check for sys/fault.h, sys/syscall.h, sys/proc.h. (NEW_PROC_API): Remove. (prsysent_t, pr_sigset_t, pr_sigaction64_t, pr_siginfo64_t): Likewise. * common/common.m4 (GDB_AC_COMMON): Don't check for sys/syscall.h. * configure: Regenerate. * config.in: Regenerate. * gdbserver/configure: Regenerate. * gdbserver/config.in: Regenerate. * i386-sol2-nat.c (_initialize_amd64_sol2_nat): Remove NEW_PROC_API test. * sparc-sol2-nat.c (_initialize_sparc_sol2_nat): Likewise. * linux-btrace.c: Remove HAVE_SYS_SYSCALL_H test. * proc-api.c: Remove !NEW_PROC_API support.

Remove ioctl-based procfs support on Solaris This is the previously mentioned patch to get rid of unstructured/ioctl-based procfs support in procfs.c. Given that support for structured procfs was introduced in Solaris 2.6 back in 1997 and we're just removing support for Solaris < 10, there's no point in carrying that baggage (and tons of support for IRIX and OSF/1 as well) around any longer. Most of the patch should be straightforward (removing support for !NEW_PROC_API, non-Solaris OSes and pre-Solaris 10 quirks). Only a few points need explanations: * <sys/syscall.h> was already included unconditionally in most places, so there's no need to have guards in a few remaining ones. * configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so NEW_PROC_API detection for those in configure.ac can go. * I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1. Theoretically, it would be better to include <procfs.h> on Solaris (which includes that define), but that breaks the build over <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux. * I've regenerated syscall_table[] in proc-events.c with a small script from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no traces of older Solaris versions and other OSes left. * prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX doesn't use procfs.c any longer, so all related code can go. The patch was generated with diff -w so one can easier see changes without being distracted by simple reindentations. So far, it has only been compiled and smoke-tested on amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and x86_64-pc-linux-gnu. Certainly needs more testing (Solaris 11.3 vs. 11.4, 32-bit gdb, testsuite once I've figured out what's wrong on Solaris 10 etc.), but it's enough to get a first impression how much cleanup is possible here. * configure.ac Don't check for sys/fault.h, sys/syscall.h, sys/proc.h.

C++-fy and prepare for sharing fork_inferior As a preparation for the next patch, which will move fork_inferior from GDB to common/ (and therefore share it with gdbserver), it is interesting to convert a few functions to C++. This patch touches functions related to parsing command-line arguments to the inferior (see gdb/fork-child.c:breakup_args), the way the arguments are stored on fork_inferior (using std::vector instead of char **), and the code responsible for dealing with argv also on gdbserver. I've taken this opportunity and decided to constify a few arguments to fork_inferior/create_inferior as well, in order to make the code cleaner. And now, on gdbserver, we're using xstrdup everywhere and aren't checking for memory allocation failures anymore, as requested by Pedro: <https://sourceware.org/ml/gdb-patches/2017-03/msg00191.html> Message-Id: <025ebdb9-90d9-d54a-c055-57ed2406b812@redhat.com> Pedro Alves wrote: > On the "== NULL" check: IIUC, the old NULL check was there to > handle strdup returning NULL due to out-of-memory. > See NULL checks and comments further above in this function. > Now that you're using a std::vector, that doesn't work or make > sense any longer, since if push_back fails to allocate space for > its internal buffer (with operator new), our operator new replacement > (common/new-op.c) calls malloc_failure, which aborts gdbserver. > > Not sure it makes sense to handle out-of-memory specially in > the gdb/rsp-facing functions nowadays (maybe git blame/log/patch > submission for that code shows some guidelines).

/* We will be looking down the PATH to find shell_file. If we
2000-01-06 04:07:20 +01:00
just do this the normal way (via execlp, which operates by
attempting an exec for each element of the PATH until it
finds one which succeeds), then there will be an exec for
each failed attempt, each of which will cause a PR_SYSEXIT
stop, and we won't know how to distinguish the PR_SYSEXIT's
for these failed execs with the ones for successful execs
(whether the exec has succeeded is stored at that time in the
carry bit or some such architecture-specific and
non-ABI-specified place).
So I can't think of anything better than to search the PATH
now. This has several disadvantages: (1) There is a race
condition; if we find a file now and it is deleted before we
exec it, we lose, even if the deletion leaves a valid file
further down in the PATH, (2) there is no way to know exactly
what an executable (in the sense of "capable of being
exec'd") file is. Using access() loses because it may lose
if the caller is the superuser; failing to use it loses if
there are ACLs or some such. */

Fix gdb C++ compilation on Solaris (PR build/20712) gdb 7.12 doesn't compile as C++ (tried with g++ 4.9) on Solaris (tried 10 and 12, sparc and x86). The following patch (relative to the 7.12 release, though I expect most if not all issues to be present on trunk, too) fixes this. Only a few of the changes bear explanation: * Initially, compilation failed whereever defs.h. was included: In file included from /vol/src/gnu/gdb/gdb-7.12/gdb/gdb.c:19:0: /vol/src/gnu/gdb/gdb-7.12/gdb/defs.h:630:33: error: 'double atof(const char*)' conflicts with a previous declaration extern double atof (const char *); /* X3.159-1989 4.10.1.1 */ ^ In file included from /usr/include/stdlib.h:17:0, from build-gnulib/import/stdlib.h:36, from /vol/src/gnu/gdb/gdb-7.12/gdb/common/common-defs.h:32, from /vol/src/gnu/gdb/gdb-7.12/gdb/defs.h:28, from /vol/src/gnu/gdb/gdb-7.12/gdb/gdb.c:19: /vol/gcc-4.9/lib/gcc/i386-pc-solaris2.10/4.9.0/include-fixed/iso/stdlib_iso.h:119:15: note: previous declaration 'double std::atof(const char*)' extern double atof(const char *); ^ This is due to this gem in gdb/defs.h which seems to have been present like forever: #ifndef atof extern double atof (const char *); /* X3.159-1989 4.10.1.1 */ #endif In the Solaris headers, the appropriate functions are in namespace std, thus the conflict. I've wrapped the defs.h declaration in !__cplusplus to avoid this; perhaps it can go completely instead. * All the casts are necessary to appease g++ and should be pretty obvious. * The sol-thread.c changes are here to handle /vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c: In function 'void _initialize_sol_thread()': /vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c:1252:36: error: invalid conversion from 'void*' to 'void (*)(int)' [-fpermissive] if (!(p_##X = dlsym (dlhandle, #X))) \ ^ /vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c:1255:3: note: in expansion of macro 'resolve' resolve (td_log); ^ and are modeled after linux-thread-db.c (try_thread_db_load_1). The patch allowed both 32 and 64-bit C++ builds on sparc-sun-solaris2.10 and i386-pc-solaris2.10 to complete. The resulting binary hasn't seen more than a smoke test (invoke it on itself, b main, run) yet. When investigating the failure to detect -static-libstdc++ support (more below), I found two more issues which only show up with -Werror: /vol/src/gnu/gdb/gdb/local/gdb/procfs.c: In function 'ssd* proc_get_LDT_entry(procinfo*, int)': /vol/src/gnu/gdb/gdb/local/gdb/procfs.c:2487:19: error: variable 'old_chain' set but not used [-Werror=unused-but-set-variable] struct cleanup *old_chain = NULL; ^ Unless I'm mistaken, you need to run do_cleanups on every return from the function.

Share fork_inferior et al with gdbserver This is the most important (and the biggest, sorry) patch of the series. It moves fork_inferior from gdb/fork-child.c to nat/fork-inferior.c and makes all the necessary adjustments to both GDB and gdbserver to make sure everything works OK. There is no "most important change" with this patch; all changes are made in a progressive way, making sure that gdbserver had the necessary features while not breaking GDB at the same time. I decided to go ahead and implement a partial support for starting the inferior with a shell on gdbserver, although the full feature comes in the next patch. The user won't have the option to disable the startup-with-shell, and also won't be able to change which shell gdbserver will use (other than setting the $SHELL environment variable, that is). Everything is working as expected, and no regressions were present during the tests. gdb/ChangeLog: 2017-06-07 Sergio Durigan Junior <sergiodj@redhat.com> Pedro Alves <palves@redhat.com> * Makefile.in (HFILES_NO_SRCDIR): Add "common/common-inferior.h" and "nat/fork-inferior.h". * common/common-inferior.h: New file, with contents from "gdb/inferior.h". * commom/common-utils.c: Include "common-utils.h".

Push pruning old threads down to the target When GDB wants to sync the thread list with the target's (e.g., due to "info threads"), it calls update_thread_list: update_thread_list (void) { prune_threads (); target_find_new_threads (); update_threads_executing (); } And then prune_threads does: prune_threads (void) { struct thread_info *tp, *next; for (tp = thread_list; tp; tp = next) { next = tp->next; if (!thread_alive (tp)) delete_thread (tp->ptid); } } Calling thread_live on each thread one by one is expensive. E.g., on Linux, it ends up doing kill(SIG0) once for each thread. Not a big deal, but still a bunch of syscalls... With the remote target, it's cumbersome. That thread_alive call ends up generating one T packet per thread: Sending packet: $Tp2141.2150#82...Packet received: OK Sending packet: $Tp2141.214f#b7...Packet received: OK Sending packet: $Tp2141.2141#82...Packet received: OK Sending packet: $qXfer:threads:read::0,fff#03...Packet received: l<threads>\n<thread id="p2141.2141" core="2"/>\n<thread id="p2141.214f" core="1"/>\n<thread id="p2141.2150" core="2"/>\n</threads>\n That seems a bit silly when target_find_new_threads method implementations will always fetch the whole current set of target threads, and then add those that are not in GDB's thread list, to GDB's thread list. This patch thus pushes down the responsibility of pruning dead threads to the target_find_new_threads method instead, so a target may implement pruning dead threads however it wants. Once we do that, target_find_new_threads becomes a misnomer, so the patch renames it to target_update_thread_list. The patch doesn't attempt to do any optimization to any target yet. It simply exports prune_threads, and makes all implementations of target_update_thread_list call that.

Push pruning old threads down to the target When GDB wants to sync the thread list with the target's (e.g., due to "info threads"), it calls update_thread_list: update_thread_list (void) { prune_threads (); target_find_new_threads (); update_threads_executing (); } And then prune_threads does: prune_threads (void) { struct thread_info *tp, *next; for (tp = thread_list; tp; tp = next) { next = tp->next; if (!thread_alive (tp)) delete_thread (tp->ptid); } } Calling thread_live on each thread one by one is expensive. E.g., on Linux, it ends up doing kill(SIG0) once for each thread. Not a big deal, but still a bunch of syscalls... With the remote target, it's cumbersome. That thread_alive call ends up generating one T packet per thread: Sending packet: $Tp2141.2150#82...Packet received: OK Sending packet: $Tp2141.214f#b7...Packet received: OK Sending packet: $Tp2141.2141#82...Packet received: OK Sending packet: $qXfer:threads:read::0,fff#03...Packet received: l<threads>\n<thread id="p2141.2141" core="2"/>\n<thread id="p2141.214f" core="1"/>\n<thread id="p2141.2150" core="2"/>\n</threads>\n That seems a bit silly when target_find_new_threads method implementations will always fetch the whole current set of target threads, and then add those that are not in GDB's thread list, to GDB's thread list. This patch thus pushes down the responsibility of pruning dead threads to the target_find_new_threads method instead, so a target may implement pruning dead threads however it wants. Once we do that, target_find_new_threads becomes a misnomer, so the patch renames it to target_update_thread_list. The patch doesn't attempt to do any optimization to any target yet. It simply exports prune_threads, and makes all implementations of target_update_thread_list call that. It's meant to be a no-op. gdb/ 2014-10-15 Pedro Alves <palves@redhat.com> * ada-tasks.c (print_ada_task_info, task_command_1): Adjust. * bsd-uthread.c (bsd_uthread_find_new_threads): Rename to ...

add "this" pointers to more target APIs A subsequent pass introduces delegation helper functions to the target API. This delegation is much cleaner if the target_ops pointer is directly available at delegation time. This patch adds the "this" pointer to various to_* methods for this purpose. This updates a number of ports which I am unable to test. Please give them a look-over.

Mostly trivial enum fixes This is a patch I extracted from Pedro's C++ branch. It contains the most trivial enum fixes, where an integer type/value was used instead of the appropriate enum type/value. It fixes many C++ errors, since in C++ you can't mix integers and enums implicitely. Regardless of the C++ conversion, I think this is a good cleanup to make use of the appropriate enum types.

Given that support for structured procfs was introduced in Solaris 2.6 back in 1997 and we're just removing support for Solaris < 10, there's no point in carrying that baggage (and tons of support for IRIX and OSF/1 as well) around any longer. Most of the patch should be straightforward (removing support for !NEW_PROC_API, non-Solaris OSes and pre-Solaris 10 quirks). Only a few points need explanations: * <sys/syscall.h> was already included unconditionally in most places, so there's no need to have guards in a few remaining ones. * configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so NEW_PROC_API detection for those in configure.ac can go. * I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1. Theoretically, it would be better to include <procfs.h> on Solaris (which includes that define), but that breaks the build over <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux. * I've regenerated syscall_table[] in proc-events.c with a small script from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no traces of older Solaris versions and other OSes left. * prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX doesn't use procfs.c any longer, so all related code can go. The patch was generated with diff -w so one can easier see changes without being distracted by simple reindentations. So far, it has only been compiled and smoke-tested on amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and x86_64-pc-linux-gnu. Certainly needs more testing (Solaris 11.3 vs. 11.4, 32-bit gdb, testsuite once I've figured out what's wrong on Solaris 10 etc.), but it's enough to get a first impression how much cleanup is possible here. * configure.ac Don't check for sys/fault.h, sys/syscall.h, sys/proc.h.

/* This part is the old method for fetching registers.
It should be replaced by the newer one using regsets
once it is implemented in this platform:
gdbarch_iterate_over_regset_sections(). */
Remove save_inferior_ptid This removes save_inferior_ptid, a cleanup function, in favor of scoped_restore. This also fixes a possible (it seems unlikely that it could happen in practice) memory leak -- save_inferior_ptid should have used make_cleanup_dtor, because it allocated memory. I tested this on the buildbot. However, there are two caveats to this. First, sometimes it seems I misread the results. Second, I think this patch touches some platforms that can't be tested by the buildbot. So, extra care seems warranted.

Fix gdb C++ compilation on Solaris (PR build/20712) gdb 7.12 doesn't compile as C++ (tried with g++ 4.9) on Solaris (tried 10 and 12, sparc and x86). The following patch (relative to the 7.12 release, though I expect most if not all issues to be present on trunk, too) fixes this. Only a few of the changes bear explanation: * Initially, compilation failed whereever defs.h. was included: In file included from /vol/src/gnu/gdb/gdb-7.12/gdb/gdb.c:19:0: /vol/src/gnu/gdb/gdb-7.12/gdb/defs.h:630:33: error: 'double atof(const char*)' conflicts with a previous declaration extern double atof (const char *); /* X3.159-1989 4.10.1.1 */ ^ In file included from /usr/include/stdlib.h:17:0, from build-gnulib/import/stdlib.h:36, from /vol/src/gnu/gdb/gdb-7.12/gdb/common/common-defs.h:32, from /vol/src/gnu/gdb/gdb-7.12/gdb/defs.h:28, from /vol/src/gnu/gdb/gdb-7.12/gdb/gdb.c:19: /vol/gcc-4.9/lib/gcc/i386-pc-solaris2.10/4.9.0/include-fixed/iso/stdlib_iso.h:119:15: note: previous declaration 'double std::atof(const char*)' extern double atof(const char *); ^ This is due to this gem in gdb/defs.h which seems to have been present like forever: #ifndef atof extern double atof (const char *); /* X3.159-1989 4.10.1.1 */ #endif In the Solaris headers, the appropriate functions are in namespace std, thus the conflict. I've wrapped the defs.h declaration in !__cplusplus to avoid this; perhaps it can go completely instead. * All the casts are necessary to appease g++ and should be pretty obvious. * The sol-thread.c changes are here to handle /vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c: In function 'void _initialize_sol_thread()': /vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c:1252:36: error: invalid conversion from 'void*' to 'void (*)(int)' [-fpermissive] if (!(p_##X = dlsym (dlhandle, #X))) \ ^ /vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c:1255:3: note: in expansion of macro 'resolve' resolve (td_log); ^ and are modeled after linux-thread-db.c (try_thread_db_load_1). The patch allowed both 32 and 64-bit C++ builds on sparc-sun-solaris2.10 and i386-pc-solaris2.10 to complete. The resulting binary hasn't seen more than a smoke test (invoke it on itself, b main, run) yet. When investigating the failure to detect -static-libstdc++ support (more below), I found two more issues which only show up with -Werror: /vol/src/gnu/gdb/gdb/local/gdb/procfs.c: In function 'ssd* proc_get_LDT_entry(procinfo*, int)': /vol/src/gnu/gdb/gdb/local/gdb/procfs.c:2487:19: error: variable 'old_chain' set but not used [-Werror=unused-but-set-variable] struct cleanup *old_chain = NULL; ^ Unless I'm mistaken, you need to run do_cleanups on every return from the function. Afterwards, I ran a 32-bit compilation, which (after adding --disable-largefile to avoid In file included from /usr/include/sys/procfs.h:28:0, from /vol/src/gnu/gdb/gdb/local/gdb/i386-sol2-nat.c:23: /usr/include/sys/old_procfs.h:39:2: error: #error "Cannot use procfs in the large file compilation environment" #error "Cannot use procfs in the large file compilation environment" ^ and two more instances) revealed /vol/src/gnu/gdb/gdb/local/gdb/top.c: In function 'void gdb_safe_append_history()': /vol/src/gnu/gdb/gdb/local/gdb/top.c:1170:59: error: format '%d' expects argument of type 'int', but argument 3 has type 'pid_t {aka long int}' [-Werror=format=] = xstrprintf ("%s-gdb%d~", history_filename, getpid ()); ^ Fixed by casting pid_t to long and printing it as such.
