/* Get the thread id for the ptrace call. */
Remove get_thread_id This patch removes get_thread_id from aarch64-linux-nat.c, arm-linux-nat.c and xtensa-linux-nat.c. get_thread_id was added in this commit below in 2000, 41c49b06c471443d3baf2eaa2463a315f9b5edca https://sourceware.org/ml/gdb-patches/2000-04/msg00398.html which predates the ptid_t stuff added into GDB. Nowadays, lwpid of inferior_ptid is only zero when the inferior is created (in fork-child.c:fork_inferior) and its lwpid will be set after linux_nat_wait_1 gets the first event. After that, lwpid of inferior_ptid is not zero for linux-nat target, then we can use ptid_get_lwp, so this function isn't needed anymore. Even when GDB attaches to a process, the lwp of inferior_ptid isn't zero, see linux-nat.c:linux_nat_attach, /* The ptrace base target adds the main thread with (pid,0,0) format. Decorate it with lwp info. */ ptid = ptid_build (ptid_get_pid (inferior_ptid), ptid_get_pid (inferior_ptid), 0); Note that linux_nat_xfer_partial shifts lwpid to pid for inferior_ptid temperately for calling linux_ops->to_xfer_partial, but all the affected functions in this patch are not called in linux_ops->to_xfer_partial. I think we can safely remove get_thread_id for all linux native targets. Regression tested on arm-linux and aarch64-linux.

/* Read the floating point state. */
Convert have_ptrace_getregset to a tri-state boolean have_ptrace_getregset is a tri-state variable (-1, 0, 1), and we have some conditions like "if (have_ptrace_getregset)", which is not correct. I'll explain why it is not correct in the following example. This fix to this problem to replace the test (have_ptrace_getregset) to test (have_ptrace_getregset == 1) or (have_ptrace_getregset == -1) etc. However Doug thinks it hinders readability https://sourceware.org/ml/gdb-patches/2015-05/msg00692.html so I decide to add a new enum tribool and change have_ptrace_getregset to it, in order to make these tests more readable. have_ptrace_getregset is initialised to -1, and is adjusted to 0 or 1 in $ARCH_linux_read_description according to the capability of the kernel. However, it is possible that have_ptrace_getregset is used before it is set to 0 or 1, which means it is still -1. This is shown below.

/* Get the thread id for the ptrace call. */
Remove get_thread_id This patch removes get_thread_id from aarch64-linux-nat.c, arm-linux-nat.c and xtensa-linux-nat.c. get_thread_id was added in this commit below in 2000, 41c49b06c471443d3baf2eaa2463a315f9b5edca https://sourceware.org/ml/gdb-patches/2000-04/msg00398.html which predates the ptid_t stuff added into GDB. Nowadays, lwpid of inferior_ptid is only zero when the inferior is created (in fork-child.c:fork_inferior) and its lwpid will be set after linux_nat_wait_1 gets the first event. After that, lwpid of inferior_ptid is not zero for linux-nat target, then we can use ptid_get_lwp, so this function isn't needed anymore. Even when GDB attaches to a process, the lwp of inferior_ptid isn't zero, see linux-nat.c:linux_nat_attach, /* The ptrace base target adds the main thread with (pid,0,0) format. Decorate it with lwp info. */ ptid = ptid_build (ptid_get_pid (inferior_ptid), ptid_get_pid (inferior_ptid), 0); Note that linux_nat_xfer_partial shifts lwpid to pid for inferior_ptid temperately for calling linux_ops->to_xfer_partial, but all the affected functions in this patch are not called in linux_ops->to_xfer_partial. I think we can safely remove get_thread_id for all linux native targets. Regression tested on arm-linux and aarch64-linux.

Convert have_ptrace_getregset to a tri-state boolean have_ptrace_getregset is a tri-state variable (-1, 0, 1), and we have some conditions like "if (have_ptrace_getregset)", which is not correct. I'll explain why it is not correct in the following example. This fix to this problem to replace the test (have_ptrace_getregset) to test (have_ptrace_getregset == 1) or (have_ptrace_getregset == -1) etc. However Doug thinks it hinders readability https://sourceware.org/ml/gdb-patches/2015-05/msg00692.html so I decide to add a new enum tribool and change have_ptrace_getregset to it, in order to make these tests more readable. have_ptrace_getregset is initialised to -1, and is adjusted to 0 or 1 in $ARCH_linux_read_description according to the capability of the kernel. However, it is possible that have_ptrace_getregset is used before it is set to 0 or 1, which means it is still -1. This is shown below.

Convert have_ptrace_getregset to a tri-state boolean have_ptrace_getregset is a tri-state variable (-1, 0, 1), and we have some conditions like "if (have_ptrace_getregset)", which is not correct. I'll explain why it is not correct in the following example. This fix to this problem to replace the test (have_ptrace_getregset) to test (have_ptrace_getregset == 1) or (have_ptrace_getregset == -1) etc. However Doug thinks it hinders readability https://sourceware.org/ml/gdb-patches/2015-05/msg00692.html so I decide to add a new enum tribool and change have_ptrace_getregset to it, in order to make these tests more readable. have_ptrace_getregset is initialised to -1, and is adjusted to 0 or 1 in $ARCH_linux_read_description according to the capability of the kernel. However, it is possible that have_ptrace_getregset is used before it is set to 0 or 1, which means it is still -1. This is shown below.

/* Get the thread id for the ptrace call. */
Remove get_thread_id This patch removes get_thread_id from aarch64-linux-nat.c, arm-linux-nat.c and xtensa-linux-nat.c. get_thread_id was added in this commit below in 2000, 41c49b06c471443d3baf2eaa2463a315f9b5edca https://sourceware.org/ml/gdb-patches/2000-04/msg00398.html which predates the ptid_t stuff added into GDB. Nowadays, lwpid of inferior_ptid is only zero when the inferior is created (in fork-child.c:fork_inferior) and its lwpid will be set after linux_nat_wait_1 gets the first event. After that, lwpid of inferior_ptid is not zero for linux-nat target, then we can use ptid_get_lwp, so this function isn't needed anymore. Even when GDB attaches to a process, the lwp of inferior_ptid isn't zero, see linux-nat.c:linux_nat_attach, /* The ptrace base target adds the main thread with (pid,0,0) format. Decorate it with lwp info. */ ptid = ptid_build (ptid_get_pid (inferior_ptid), ptid_get_pid (inferior_ptid), 0); Note that linux_nat_xfer_partial shifts lwpid to pid for inferior_ptid temperately for calling linux_ops->to_xfer_partial, but all the affected functions in this patch are not called in linux_ops->to_xfer_partial. I think we can safely remove get_thread_id for all linux native targets. Regression tested on arm-linux and aarch64-linux.

Convert have_ptrace_getregset to a tri-state boolean have_ptrace_getregset is a tri-state variable (-1, 0, 1), and we have some conditions like "if (have_ptrace_getregset)", which is not correct. I'll explain why it is not correct in the following example. This fix to this problem to replace the test (have_ptrace_getregset) to test (have_ptrace_getregset == 1) or (have_ptrace_getregset == -1) etc. However Doug thinks it hinders readability https://sourceware.org/ml/gdb-patches/2015-05/msg00692.html so I decide to add a new enum tribool and change have_ptrace_getregset to it, in order to make these tests more readable. have_ptrace_getregset is initialised to -1, and is adjusted to 0 or 1 in $ARCH_linux_read_description according to the capability of the kernel. However, it is possible that have_ptrace_getregset is used before it is set to 0 or 1, which means it is still -1. This is shown below.

/* Get the thread id for the ptrace call. */
Remove get_thread_id This patch removes get_thread_id from aarch64-linux-nat.c, arm-linux-nat.c and xtensa-linux-nat.c. get_thread_id was added in this commit below in 2000, 41c49b06c471443d3baf2eaa2463a315f9b5edca https://sourceware.org/ml/gdb-patches/2000-04/msg00398.html which predates the ptid_t stuff added into GDB. Nowadays, lwpid of inferior_ptid is only zero when the inferior is created (in fork-child.c:fork_inferior) and its lwpid will be set after linux_nat_wait_1 gets the first event. After that, lwpid of inferior_ptid is not zero for linux-nat target, then we can use ptid_get_lwp, so this function isn't needed anymore. Even when GDB attaches to a process, the lwp of inferior_ptid isn't zero, see linux-nat.c:linux_nat_attach, /* The ptrace base target adds the main thread with (pid,0,0) format. Decorate it with lwp info. */ ptid = ptid_build (ptid_get_pid (inferior_ptid), ptid_get_pid (inferior_ptid), 0); Note that linux_nat_xfer_partial shifts lwpid to pid for inferior_ptid temperately for calling linux_ops->to_xfer_partial, but all the affected functions in this patch are not called in linux_ops->to_xfer_partial. I think we can safely remove get_thread_id for all linux native targets. Regression tested on arm-linux and aarch64-linux.

/* Get the thread id for the ptrace call. */
Remove get_thread_id This patch removes get_thread_id from aarch64-linux-nat.c, arm-linux-nat.c and xtensa-linux-nat.c. get_thread_id was added in this commit below in 2000, 41c49b06c471443d3baf2eaa2463a315f9b5edca https://sourceware.org/ml/gdb-patches/2000-04/msg00398.html which predates the ptid_t stuff added into GDB. Nowadays, lwpid of inferior_ptid is only zero when the inferior is created (in fork-child.c:fork_inferior) and its lwpid will be set after linux_nat_wait_1 gets the first event. After that, lwpid of inferior_ptid is not zero for linux-nat target, then we can use ptid_get_lwp, so this function isn't needed anymore. Even when GDB attaches to a process, the lwp of inferior_ptid isn't zero, see linux-nat.c:linux_nat_attach, /* The ptrace base target adds the main thread with (pid,0,0) format. Decorate it with lwp info. */ ptid = ptid_build (ptid_get_pid (inferior_ptid), ptid_get_pid (inferior_ptid), 0); Note that linux_nat_xfer_partial shifts lwpid to pid for inferior_ptid temperately for calling linux_ops->to_xfer_partial, but all the affected functions in this patch are not called in linux_ops->to_xfer_partial. I think we can safely remove get_thread_id for all linux native targets. Regression tested on arm-linux and aarch64-linux.

Remove get_thread_id This patch removes get_thread_id from aarch64-linux-nat.c, arm-linux-nat.c and xtensa-linux-nat.c. get_thread_id was added in this commit below in 2000, 41c49b06c471443d3baf2eaa2463a315f9b5edca https://sourceware.org/ml/gdb-patches/2000-04/msg00398.html which predates the ptid_t stuff added into GDB. Nowadays, lwpid of inferior_ptid is only zero when the inferior is created (in fork-child.c:fork_inferior) and its lwpid will be set after linux_nat_wait_1 gets the first event. After that, lwpid of inferior_ptid is not zero for linux-nat target, then we can use ptid_get_lwp, so this function isn't needed anymore. Even when GDB attaches to a process, the lwp of inferior_ptid isn't zero, see linux-nat.c:linux_nat_attach, /* The ptrace base target adds the main thread with (pid,0,0) format. Decorate it with lwp info. */ ptid = ptid_build (ptid_get_pid (inferior_ptid), ptid_get_pid (inferior_ptid), 0); Note that linux_nat_xfer_partial shifts lwpid to pid for inferior_ptid temperately for calling linux_ops->to_xfer_partial, but all the affected functions in this patch are not called in linux_ops->to_xfer_partial. I think we can safely remove get_thread_id for all linux native targets. Regression tested on arm-linux and aarch64-linux.

Convert have_ptrace_getregset to a tri-state boolean have_ptrace_getregset is a tri-state variable (-1, 0, 1), and we have some conditions like "if (have_ptrace_getregset)", which is not correct. I'll explain why it is not correct in the following example. This fix to this problem to replace the test (have_ptrace_getregset) to test (have_ptrace_getregset == 1) or (have_ptrace_getregset == -1) etc. However Doug thinks it hinders readability https://sourceware.org/ml/gdb-patches/2015-05/msg00692.html so I decide to add a new enum tribool and change have_ptrace_getregset to it, in order to make these tests more readable. have_ptrace_getregset is initialised to -1, and is adjusted to 0 or 1 in $ARCH_linux_read_description according to the capability of the kernel. However, it is possible that have_ptrace_getregset is used before it is set to 0 or 1, which means it is still -1. This is shown below.

Convert have_ptrace_getregset to a tri-state boolean have_ptrace_getregset is a tri-state variable (-1, 0, 1), and we have some conditions like "if (have_ptrace_getregset)", which is not correct. I'll explain why it is not correct in the following example. This fix to this problem to replace the test (have_ptrace_getregset) to test (have_ptrace_getregset == 1) or (have_ptrace_getregset == -1) etc. However Doug thinks it hinders readability https://sourceware.org/ml/gdb-patches/2015-05/msg00692.html so I decide to add a new enum tribool and change have_ptrace_getregset to it, in order to make these tests more readable. have_ptrace_getregset is initialised to -1, and is adjusted to 0 or 1 in $ARCH_linux_read_description according to the capability of the kernel. However, it is possible that have_ptrace_getregset is used before it is set to 0 or 1, which means it is still -1. This is shown below.

Remove get_thread_id This patch removes get_thread_id from aarch64-linux-nat.c, arm-linux-nat.c and xtensa-linux-nat.c. get_thread_id was added in this commit below in 2000, 41c49b06c471443d3baf2eaa2463a315f9b5edca https://sourceware.org/ml/gdb-patches/2000-04/msg00398.html which predates the ptid_t stuff added into GDB. Nowadays, lwpid of inferior_ptid is only zero when the inferior is created (in fork-child.c:fork_inferior) and its lwpid will be set after linux_nat_wait_1 gets the first event. After that, lwpid of inferior_ptid is not zero for linux-nat target, then we can use ptid_get_lwp, so this function isn't needed anymore. Even when GDB attaches to a process, the lwp of inferior_ptid isn't zero, see linux-nat.c:linux_nat_attach, /* The ptrace base target adds the main thread with (pid,0,0) format. Decorate it with lwp info. */ ptid = ptid_build (ptid_get_pid (inferior_ptid), ptid_get_pid (inferior_ptid), 0); Note that linux_nat_xfer_partial shifts lwpid to pid for inferior_ptid temperately for calling linux_ops->to_xfer_partial, but all the affected functions in this patch are not called in linux_ops->to_xfer_partial. I think we can safely remove get_thread_id for all linux native targets. Regression tested on arm-linux and aarch64-linux.

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 Linux ptrace interface to hardware break-/watch-points presents the
values in a vector centred around 0 (which is used fo generic information).
Positive indicies refer to breakpoint addresses/control registers, negative
indices to watchpoint addresses/control registers.
The Linux vector is indexed as follows:
-((i << 1) + 2): Control register for watchpoint i.
-((i << 1) + 1): Address register for watchpoint i.
0: Information register.
((i << 1) + 1): Address register for breakpoint i.
((i << 1) + 2): Control register for breakpoint i.
This structure is used as a per-thread cache of the state stored by the
kernel, so that we don't need to keep calling into the kernel to find a
free breakpoint.
We treat break-/watch-points with their enable bit clear as being deleted.

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.

Avoid software breakpoint's instruction shadow inconsistency This change: commit b775012e845380ed4c7421a1b87caf7bfae39f5f Author: Luis Machado <luisgpm@br.ibm.com> Date: Fri Feb 24 15:10:59 2012 +0000 2012-02-24 Luis Machado <lgustavo@codesourcery.com> * remote.c (remote_supports_cond_breakpoints): New forward declaration. [...] changed the way breakpoints are inserted and removed such that `insert_bp_location' can now be called with the breakpoint being handled already in place, while previously the call was only ever made for breakpoints that have not been put in place. This in turn caused an issue for software breakpoints and targets for which a breakpoint's `placed_address' may not be the same as the original requested address. The issue is `insert_bp_location' overwrites the previously adjusted value in `placed_address' with the original address, that is only replaced back with the correct adjusted address later on when `gdbarch_breakpoint_from_pc' is called. Meanwhile there's a window where the value in `placed_address' does not correspond to data stored in `shadow_contents', leading to incorrect instruction bytes being supplied when `one_breakpoint_xfer_memory' is called to supply the instruction overlaid by the breakpoint. And this is exactly what happens on the MIPS target with software breakpoints placed in microMIPS code. In this case not only `placed_address' is not the original address because of the ISA bit, but `mips_breakpoint_from_pc' has to read the original instruction to determine which one of the two software breakpoint instruction encodings to choose as well. The 16-bit encoding is used to replace 16-bit instructions and similarly the 32-bit one is used with 32-bit instructions, to satisfy branch delay slot size requirements. The mismatch between `placed_address' and the address data in `shadow_contents' has been obtained from leads to the wrong encoding being used in some cases, which in the case of a 32-bit software breakpoint instruction replacing a 16-bit instruction causes corruption to the adjacent following instruction and leads the debug session astray if execution reaches there e.g. with a jump. To address this problem I made the change below, that adds a `reqstd_address' field to `struct bp_target_info' and leaves `placed_address' unchanged once it has been set. This ensures data in `shadow_contents' is always consistent with `placed_address'. This approach also has this good side effect that all the places that examine the breakpoint's address see a consistent value, either `reqstd_address' or `placed_address', as required. Currently some places see either the original or the adjusted address in `placed_address', depending on whether they have been called before `gdbarch_remote_breakpoint_from_pc' or afterwards. This is in particular true for subsequent calls to `gdbarch_remote_breakpoint_from_pc' itself, e.g. from `one_breakpoint_xfer_memory'. This is also important for places like `find_single_step_breakpoint' where a breakpoint's address is compared to the raw value of $pc. * breakpoint.h (bp_target_info): Add `reqstd_address' member, update comments. * breakpoint.c (one_breakpoint_xfer_memory): Use `reqstd_address' for the breakpoint's address.

static arm_hwbp_type
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.

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. Regression-tested on native x86_64. gdb/ChangeLog: * aarch64-linux-nat.c (aarch64_linux_can_use_hw_breakpoint): Use enum type or value instead of integer. (aarch64_linux_insert_watchpoint): Likewise.

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. Regression-tested on native x86_64. gdb/ChangeLog: * aarch64-linux-nat.c (aarch64_linux_can_use_hw_breakpoint): Use enum type or value instead of integer. (aarch64_linux_insert_watchpoint): Likewise.
