Remove null_block_symbol
This removes null_block_symbol. It seemed simpler to me to change initializations and returns to use value initialization rather than null_block_symbol. This also fixes up a few spots where initialization was done piecemeal. gdb/ChangeLog 2019-03-24 Tom Tromey <tom@tromey.com> * ada-lang.c (standard_lookup): Simplify initialization.

Handle an edge case for minisym TLS variable lookups.
If a TLS variable is provided by a minisym from a separate debug file, the separate debug file is passed to gdbarch_fetch_tls_load_module_address. However, the object files stored in the shared object list are the original object files, not the separate debug object files. In this case, svr4_fetch_objfile_link_map was failing to find the link map entry since the debug object file is not in its internal list, only the original object file. gdb/ChangeLog: * solib-svr4.c (svr4_fetch_objfile_link_map): Look for objfile->separate_debug_objfile_backlink if not NULL. |

Update copyright year range in all GDB files.
This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files. |

Fix debugging of stripped PIE executables with padded PT_TLS
Certain PIE executables produced by gold cannot be debugged by gdb after being stripped. GDB requires program headers of PIE executables to match, and those checks may fail due to adjustments made during stripping. One case of this occurs because strip recomputes the memsz of PT_TLS and does not add alignment, while gold does. This is another variant of PR 11786, so apply the same fix of relaxing the program header matching. gdb/ChangeLog: PR gdb/11786 * solib-svr4.c (svr4_exec_displacement): Ignore memsz fields for PT_TLS segments. gdb/testsuite/ChangeLog: PR gdb/11786 * gdb.base/gcore-tls-pie.c: New file. * gdb.base/gcore-tls-pie.exp: New file. |

target_stack -> current_top_target() throughout
The recent C++ification of target_ops replaced references to the old "current_target" squashed target throughout with references to a "target_stack" pointer. I had picked the "target_stack" name very early in the multi-target work, and managed to stick with it, even though it's a bit of a misnomer, since it isn't really a "target stack" object, but a pointer into the current top target in the stack. As I'm splitting more pieces off of the multi-target branch, I've come to think that it's better to rename it now. A following patch will introduce a new class to represent a target stack, and "target_stack" would be _its_ ideal name. (In the branch, the class is called a_target_stack to work around the clash.) Thus this commit renames target_stack to current_top_target and replaces all references throughout. Also, while at it, current_top_target is made a function instead of a pointer, to make it possible to change its internal implementation without leaking implementation details out. In a couple patches, the implementation of the function will change to refer to a target stack object, and then further down the multi-target work, it'll change again to find the right target stack for the current inferior. gdb/ChangeLog: 2018-06-07 Pedro Alves <palves@redhat.com> * target.h (target_stack): Delete.

Convert struct target_ops to C++
I.e., use C++ virtual methods and inheritance instead of tables of function pointers. Unfortunately, there's no way to do a smooth transition. ALL native targets in the tree must be converted at the same time. I've tested all I could with cross compilers and with help from GCC compile farm, but naturally I haven't been able to test many of the ports. Still, I made a best effort to port everything over, and while I expect some build problems due to typos and such, which should be trivial to fix, I don't expect any design problems. * Implementation notes: - The flattened current_target is gone. References to current_target or current_target.beneath are replaced with references to target_stack (the top of the stack) directly. - To keep "set debug target" working, this adds a new debug_stratum layer that sits on top of the stack, prints the debug, and delegates to the target beneath. In addition, this makes the shortname and longname properties of target_ops be virtual methods instead of data fields, and makes the debug target defer those to the target beneath. This is so that debug code sprinkled around that does "if (debugtarget) ..." can transparently print the name of the target beneath. A patch later in the series actually splits out the shortname/longname methods to a separate structure, but I preferred to keep that chance separate as it is associated with changing a bit the design of how targets are registered and open. - Since you can't check whether a C++ virtual method is overridden, the old method of checking whether a target_ops implements a method by comparing the function pointer must be replaced with something else. Some cases are fixed by adding a parallel "can_do_foo" target_ops methods. E.g.,: + for (t = target_stack; t != NULL; t = t->beneath) { - if (t->to_create_inferior != NULL) + if (t->can_create_inferior ()) break; } Others are fixed by changing void return type to bool or int return type, and have the default implementation return false or -1, to indicate lack of support. - make-target-delegates was adjusted to generate C++ classes and methods. It needed tweaks to grok "virtual" in front of the target method name, and for the fact that methods are no longer function pointers. (In particular, the current code parsing the return type was simple because it could simply parse up until the '(' in '(*to_foo)'. It now generates a couple C++ classes that inherit target_ops: dummy_target and debug_target. Since we need to generate the class declarations as well, i.e., we need to emit methods twice, we now generate the code in two passes. - The core_target global is renamed to avoid conflict with the "core_target" class. - ctf/tfile targets init_tracefile_ops is replaced by a base class that is inherited by both ctf and tfile. - bsd-uthread The bsd_uthread_ops_hack hack is gone. It's not needed because nothing was extending a target created by bsd_uthread_target. - remote/extended-remote targets This is a first pass, just enough to C++ify target_ops. A later pass will convert more free functions to methods, and make remote_state be truly per remote instance, allowing multiple simultaneous instances of remote targets. - inf-child/"native" is converted to an actual base class (inf_child_target), that is inherited by all native targets. - GNU/Linux The old weird double-target linux_ops mechanism in linux-nat.c, is gone, replaced by adding a few virtual methods to linux-nat.h's target_ops, called low_XXX, that the concrete linux-nat implementations override. Sort of like gdbserver's linux_target_ops, but simpler, for requiring only one target_ops-like hierarchy, which spares implementing the same method twice when we need to forward the method to a low implementation. The low target simply reimplements the target_ops method directly in that case. There are a few remaining linux-nat.c hooks that would be better converted to low_ methods like above too. E.g.: linux_nat_set_new_thread (t, x86_linux_new_thread); linux_nat_set_new_fork (t, x86_linux_new_fork); linux_nat_set_forget_process That'll be done in a follow up patch. - We can no longer use functions like x86_use_watchpoints to install custom methods on an arbitrary base target. The patch replaces instances of such a pattern with template mixins. For example memory_breakpoint_target defined in target.h, or x86_nat_target in x86-nat.h. - linux_trad_target, MIPS and Alpha GNU/Linux The code in the new linux-nat-trad.h/c files which was split off of inf-ptrace.h/c recently, is converted to a C++ base class, and used by the MIPS and Alpha GNU/Linux ports. - BSD targets The $architecture x NetBSD/OpenBSD/FreeBSD support matrix complicates things a bit. There's common BSD target code, and there's common architecture-specific code shared between the different BSDs. Currently, all that is stiched together to form a final target, via the i386bsd_target, x86bsd_target, fbsd_nat_add_target functions etc. This introduces new fbsd_nat_target, obsd_nat_target and nbsd_nat_target classes that serve as base/prototype target for the corresponding BSD variant. And introduces generic i386/AMD64 BSD targets, to be used as template mixin to build a final target. Similarly, a generic SPARC target is added, used by both BSD and Linux ports. - bsd_kvm_add_target, BSD libkvm target I considered making bsd_kvm_supply_pcb a virtual method, and then have each port inherit bsd_kvm_target and override that method, but that was resulting in lots of unjustified churn, so I left the function pointer mechanism alone. gdb/ChangeLog: 2018-05-02 Pedro Alves <palves@redhat.com> John Baldwin <jhb@freebsd.org> * target.h (enum strata) <debug_stratum>: New.

Make target_read_alloc & al return vectors
This patch started by changing target_read_alloc_1 to return a byte_vector, to avoid manual memory management (in target_read_alloc_1 and in the callers). To communicate failures to the callers, it actually returns a gdb::optional<gdb::byte_vector>. Adjusting target_read_stralloc was a bit more tricky, since it wants to return a buffer of char, and not gdb_byte. Since you can't just cast a gdb::byte_vector into a gdb::def_vector<char>, I made target_read_alloc_1 templated, so both versions (that return vectors of gdb_byte and char) are generated. Since target_read_stralloc now returns a gdb::char_vector instead of a gdb::unique_xmalloc_ptr<char>, a few callers need to be adjusted. gdb/ChangeLog: * common/byte-vector.h (char_vector): New type. * target.h (target_read_alloc): Return gdb::optional<byte_vector>.

Convert observers to C++
This converts observers from using a special source-generating script to be plain C++. This version of the patch takes advantage of C++11 by using std::function and variadic templates; incorporates Pedro's patches; and renames the header file to "observable.h" (this change eliminates the need for a clean rebuild). Note that Pedro's patches used a template lambda in tui-hooks.c, but this failed to compile on some buildbot instances (presumably due to differing C++ versions); I replaced this with an ordinary template function.

Convert generic probe interface to C++ (and perform some cleanups)
This patch converts the generic probe interface (gdb/probe.[ch]) to C++, and also performs some cleanups that were on my TODO list for a while. The main changes were the conversion of 'struct probe' to 'class probe', and 'struct probe_ops' to 'class static_probe_ops'. The former now contains all the "dynamic", generic methods that act on a probe + the generic data related to it; the latter encapsulates a bunch of "static" methods that relate to the probe type, but not to a specific probe itself. I've had to do a few renamings (e.g., on 'struct bound_probe' the field is called 'probe *prob' now, instead of 'struct probe *probe') because GCC was complaining about naming the field using the same name as the class. Nothing major, though. Generally speaking, the logic behind and the design behind the code are the same. Even though I'm sending a series of patches, they need to be tested and committed as a single unit, because of inter-dependencies. But it should be easier to review in separate logical units. I've regtested this patch on BuildBot, no regressions found. gdb/ChangeLog: 2017-11-22 Sergio Durigan Junior <sergiodj@redhat.com> * break-catch-throw.c (fetch_probe_arguments): Use 'probe.prob' instead of 'probe.probe'. * breakpoint.c (create_longjmp_master_breakpoint): Call 'can_evaluate_arguments' and 'get_relocated_address' methods from probe.

Return unique_xmalloc_ptr from target_read_stralloc
This changes target_read_stralloc to return a unique_xmalloc_ptr, and then fixes all the callers. unique_xmalloc_ptr is used, rather than std::string, because target_read_stralloc gives a special meaning to a NULL return. ChangeLog 2017-10-16 Tom Tromey <tom@tromey.com> * xml-syscall.c (xml_init_syscalls_info): Update. * xml-support.c (xinclude_start_include): Update. (xml_fetch_content_from_file): Return unique_xmalloc_ptr. * xml-support.h (xml_fetch_another): Return unique_xmalloc_ptr. (xml_fetch_content_from_file): Likewise. * osdata.c (get_osdata): Update. * target.h (target_read_stralloc, target_get_osdata): Return unique_xmalloc_ptr. * solib-aix.c (solib_aix_get_library_list): Update. * solib-target.c (solib_target_current_sos): Update. * solib-svr4.c (svr4_current_sos_via_xfer_libraries): Update. * xml-tdesc.c (fetch_available_features_from_target): Update.

Eliminate catch_errors
If you want to use catch_errors with a function with parameters, then currently you have to manually write a "capture" struct wrapping the arguments and marshall/unmarshall that. https://sourceware.org/ml/gdb-patches/2017-09/msg00834.html proposed adjusting catch_errors to use gdb::function_view, which would allow passing lambdas with automatic captures. However, it seems like using TRY/CATCH directly instead ends up producing clearer and easier to debug code. This is what this commit does. Note that removing catch_errors exposes further cleanup opportunities around no longer having to follow catch_errors callback type, and also removes a few cleanups. I didn't do anything to save/restore current_uiout because I think that should be the responsibility of the code that changes current_uiout in the first place. (Another approach could be to make catch_errors a variadic template like: template<typename Function, typename... Args> int catch_errors (const char *errstring, return_mask mask, Function &&func, Args... args); and then with: extern void function_with_args (int, int); extern void function_with_no_args (); calls to the above functions would be wrapped like this: catch_errors ("some error happened", RETURN_MASK_ERROR, function_with_args, arg1, arg2); catch_errors ("some error happened", RETURN_MASK_ERROR, function_with_no_args); but I'm thinking that that doesn't improve much if at all either.) gdb/ChangeLog 2017-10-10 Pedro Alves <palves@redhat.com> Tom Tromey <tom@tromey.com> * breakpoint.c (breakpoint_cond_eval): Change return type to bool and reverse logic.

Class-ify lm_info_svr4
This patch makes lm_info_svr4 a "real" class. It initializes fields, uses bool and replaces XCNEW/xfree with new/delete. The memcpy in svr4_copy_library_list is replaced by a usage of the default copy constructor. gdb/ChangeLog: * solib-svr4.h (struct lm_info_svr4): Initialize fields. <l_addr_p>: Change type to bool. * solib-svr4.c (lm_info_read): Allocate lm_info_svr4 with new.

Make various lm_info implementations inherit from a base class
The lm_info structure is used to store target specific information about mapped libraries. It is currently defined as an opaque type in solist.h and a pointer to it is included in solist, the target-agnostic object representing a loaded shared library. Multiple targets define their own implementation of lm_info. In anticipation of using C++ stuff (e.g. vector) in the lm_info objects, we first need to avoid different definitions of classes with the same name (which violates the one definition rule). This patch does it by having a base class (lm_info_base) from which all the specific lm_info derive. Each implementation is renamed to something that makes sense (e.g. lm_info_aix for AIX). The next logical step would probably be to derive directly from so_list, it's not really obvious, so I'll keep that for another day. One special case is the Neutrino (nto) support. It uses SVR4-style libraries, but overrides some methods. To do that, it needed to have its own copy of SVR4's lm_info structure in nto-tdep.c, because it was just not possible to put it in solib-svr4.h and include that file. Over time, that copy got out of sync, which is still the case today. I can only assume that the lm_addr function in nto-tdep.c is broken right now. The first field of the old lm_info was a pointer (gdb_byte *), whereas in the new lm_info it's an address in the inferior (CORE_ADDR). Trying to use that field today probably results in a crash. With this refactor, it's now possible to put lm_info_svr4 in solib-svr4.h and just include it. I have adapted the code in nto-tdep.c to that it builds, but it's probably not correct. Since I don't have the knowledge nor setup to try this on Neutrino, somebody else would have to fix it. But I am confident that I am not making things worse than they already are. gdb/ChangeLog: * solist.h (struct lm_info): Remove. (struct lm_info_base): New class.

Use class to manage BFD reference counts
This introduces a new specialization of gdb::ref_ptr that can be used to manage BFD reference counts. Then it changes most places in gdb to use this new class, rather than explicit reference-counting or cleanups. This patch removes make_cleanup_bfd_unref. If you look you will see a couple of spots using "release" where a use of gdb_bfd_ref_ptr would be cleaner. These will be fixed in the next patch. I think this patch fixes some latent bugs. For example, it seems to me that previously objfpy_add_separate_debug_file leaked a BFD. I'm not 100% certain that the macho_symfile_read_all_oso change is correct. The existing code here is hard for me to follow. One goal of this sort of automated reference counting, though, is to make it more difficult to make logic errors; so hopefully the code is clear now. 2017-01-10 Tom Tromey <tom@tromey.com> * windows-tdep.c (windows_xfer_shared_library): Update. * windows-nat.c (windows_make_so): Update. * utils.h (make_cleanup_bfd_unref): Remove. * utils.c (do_bfd_close_cleanup, make_cleanup_bfd_unref): Remove. * symfile.h (symfile_bfd_open) (find_separate_debug_file_in_section): Return gdb_bfd_ref_ptr. * symfile.c (read_symbols, symbol_file_add) (separate_debug_file_exists): Update.

PR 20569, segv in follow_exec
The following testcases make GDB crash whenever an invalid sysroot is provided, when GDB is unable to find a valid path to the symbol file: gdb.base/catch-syscall.exp gdb.base/execl-update-breakpoints.exp gdb.base/foll-exec-mode.exp gdb.base/foll-exec.exp gdb.base/foll-vfork.exp gdb.base/pie-execl.exp gdb.multi/bkpt-multi-exec.exp gdb.python/py-finish-breakpoint.exp gdb.threads/execl.exp gdb.threads/non-ldr-exc-1.exp gdb.threads/non-ldr-exc-2.exp gdb.threads/non-ldr-exc-3.exp gdb.threads/non-ldr-exc-4.exp gdb.threads/thread-execl.exp The immediate cause of the segv is that follow_exec is passing a NULL argument (the result of exec_file_find) to strlen. However, the problem is deeper than that: follow_exec simply isn't prepared for the case where sysroot translation fails to locate the new executable. Actually all callers of exec_file_find have bugs due to confusion between host and target pathnames. This commit attempts to fix all that. In terms of the testcases that were formerly segv'ing, GDB now prints a warning but continues execution of the new program, so that the tests now mostly FAIL instead. You could argue the FAILs are due to a legitimate problem with the test environment setting up the sysroot translation incorrectly. A new representative test is added which exercises the ne wwarning code path even with native testing.

Add casts to memory allocation related calls
Most allocation functions (if not all) return a void* pointing to the allocated memory. In C++, we need to add an explicit cast when assigning the result to a pointer to another type (which is the case more often than not). The content of this patch is taken from Pedro's branch, from commit "(mostly) auto-generated patch to insert casts needed for C++". I validated that the changes make sense and manually reflowed the code to make it respect the coding style. I also found multiple places where I could use XNEW/XNEWVEC/XRESIZEVEC/etc. Thanks a lot to whoever did that automated script to insert casts, doing it completely by hand would have taken a ridiculous amount of time. Only files built on x86 with --enable-targets=all are modified. This means that all other -nat.c files are untouched and will have to be dealt with later by using appropiate compilers. Or maybe we can try to build them with a regular g++ just to know where to add casts, I don't know. I built-tested this with --enable-targets=all and reg-tested. Here's the changelog entry, which was not too bad to make despite the size, thanks to David Malcom's script. I fixed some bits by hand, but there might be some wrong parts left (hopefully not). gdb/ChangeLog: * aarch64-linux-tdep.c (aarch64_stap_parse_special_token): Add cast to allocation result assignment. * ada-exp.y (write_object_renaming): Likewise.

Initialize yet another variable to silence GCC warning from last-but-one commit
Yet another BuildBot e-mail, yet another breakage on RHEL-7.1 s390x (which uses an older GCC). This time, solib-svr4.c:solib_event_probe_action has the probe_argc variable, which is now inside a TRY..CATCH and therefore needs to be initialized. Pushed as obvious. gdb/ChangeLog: 2015-09-01 Sergio Durigan Junior <sergiodj@redhat.com> * solib-svr4.c (solib_event_probe_action): Initialize 'probe_argc' as zero. |

Initialize variable and silence GCC warning from last commit
BuildBot e-mailed me to let me know that my last commit broke GDB on RHEL-7.1 s390x. On solib-svr4.c:svr4_handle_solib_event, 'val' now needs to be initialized as NULL because it is inside a TRY..CATCH block. This patch does that. Pushed as obvious. gdb/ChangeLog: 2015-09-01 Sergio Durigan Junior <sergiodj@redhat.com> * solib-svr4.c (svr4_handle_solib_event): Initialize 'val' as NULL |

Catching errors on probes-based dynamic linker interface
This patch is intended to make the interaction between the probes-based dynamic linker interface and the SystemTap SDT probe code on GDB more robust. It does that by wrapping the calls to the probe API with TRY...CATCH'es, so that any exception thrown will be caught and handled properly. The idea for this patch came from <https://bugzilla.redhat.com/show_bug.cgi?id=1196181>, which is a bug initially filed against Fedora GDB (but now under Fedora GLIBC). This bug happens on armhfp (although it could happen on other targets as well), and is triggered because GCC generates a strange argument for one of the probes used by GDB in the dynamic linker interface. As can be seen in the bug, this argument is "-4@.L1052". I don't want to discuss the reasons for this argument to be there (this discussion belongs to the bug, or to another thread), but GDB could definitely do a better error handling here. Currently, one sees the following message when there is an error in the probes-based dynamic linker interface: (gdb) run Starting program: /bin/inferior warning: Probes-based dynamic linker interface failed. Reverting to original interface. Cannot parse expression `.L976 4@r4'. (gdb) Which means that one needs to explicitly issue a "continue" command to make GDB continue running the inferior, even though this error is not fatal and GDB will fallback to the old interface automatically. This is where this patch helps: it makes GDB still print the necessary warnings or error messages, but it *also* does not stop the inferior unnecessarily. I have tested this patch on the systems where this error happens, but I could not come up with a way to create a testcase for it. Nevertheless, it should be straightforward to see that this patch does improve the current situation. gdb/ChangeLog: 2015-09-01 Sergio Durigan Junior <sergiodj@redhat.com> * solib-svr4.c (solib_event_probe_action): Call get_probe_argument_count using TRY...CATCH. (svr4_handle_solib_event): Likewise, for evaluate_probe_argument. |

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.

Replace the block_found global with explicit data-flow
As Pedro suggested on gdb-patches@ (see https://sourceware.org/ml/gdb-patches/2015-05/msg00714.html), this change makes symbol lookup functions return a structure that includes both the symbol found and the block in which it was found. This makes it possible to get rid of the block_found global variable and thus makes block hunting explicit. gdb/ * ada-exp.y (write_object_renaming): Replace struct ada_symbol_info with struct block_symbol.

Catch exception on solib_svr4_r_ldsomap
When loading a corefile that has some inaccessible memory region(s), GDB complains about it: (gdb) core /my/corefile [New LWP 28468] Cannot access memory at address 0x355fc21148 Cannot access memory at address 0x355fc21140 (gdb) However, despite not seeing the message "Core was generated by...", it is still possible to inspect the corefile using regular GDB commands. The reason for that is because read_memory_unsigned_integer throws an exception when it cannot read the memory region, but solib_svr4_r_ldsomap was not catching it. The fix is to catch the exception and act accordingly. Tested on Fedora 20 x86_64, no regressions found. gdb/ChangeLog: 2015-03-31 Sergio Durigan Junior <sergiodj@redhat.com> * solib-svr4.c (solib_svr4_r_ldsomap): Catch possible exception by read_memory_unsigned_integer. |

Split TRY_CATCH into TRY + CATCH
This patch splits the TRY_CATCH macro into three, so that we go from this: ~~~ volatile gdb_exception ex; TRY_CATCH (ex, RETURN_MASK_ERROR) { } if (ex.reason < 0) { } ~~~ to this: ~~~ TRY { } CATCH (ex, RETURN_MASK_ERROR) { } END_CATCH ~~~ Thus, we'll be getting rid of the local volatile exception object, and declaring the caught exception in the catch block. This allows reimplementing TRY/CATCH in terms of C++ exceptions when building in C++ mode, while still allowing to build GDB in C mode (using setjmp/longjmp), as a transition step. TBC, after this patch, is it _not_ valid to have code between the TRY and the CATCH blocks, like: TRY { } // some code here. CATCH (ex, RETURN_MASK_ERROR) { } END_CATCH Just like it isn't valid to do that with C++'s native try/catch. By switching to creating the exception object inside the CATCH block scope, we can get rid of all the explicitly allocated volatile exception objects all over the tree, and map the CATCH block more directly to C++'s catch blocks. The majority of the TRY_CATCH -> TRY+CATCH+END_CATCH conversion was done with a script, rerun from scratch at every rebase, no manual editing involved. After the mechanical conversion, a few places needed manual intervention, to fix preexisting cases where we were using the exception object outside of the TRY_CATCH block, and cases where we were using "else" after a 'if (ex.reason) < 0)' [a CATCH after this patch]. The result was folded into this patch so that GDB still builds at each incremental step. END_CATCH is necessary for two reasons: First, because we name the exception object in the CATCH block, which requires creating a scope, which in turn must be closed somewhere. Declaring the exception variable in the initializer field of a for block, like: #define CATCH(EXCEPTION, mask) \ for (struct gdb_exception EXCEPTION; \ exceptions_state_mc_catch (&EXCEPTION, MASK); \ EXCEPTION = exception_none) would avoid needing END_CATCH, but alas, in C mode, we build with C90, which doesn't allow mixed declarations and code. Second, because when TRY/CATCH are wired to real C++ try/catch, as long as we need to handle cleanup chains, even if there's no CATCH block that wants to catch the exception, we need for stop at every frame in the unwind chain and run cleanups, then rethrow. That will be done in END_CATCH. After we require C++, we'll still need TRY/CATCH/END_CATCH until cleanups are completely phased out -- TRY/CATCH in C++ mode will save/restore the current cleanup chain, like in C mode, and END_CATCH catches otherwise uncaugh exceptions, runs cleanups and rethrows, so that C++ cleanups and exceptions can coexist. IMO, this still makes the TRY/CATCH code look a bit more like a newcomer would expect, so IMO worth it even if we weren't considering C++. gdb/ChangeLog. 2015-03-07 Pedro Alves <palves@redhat.com> * common/common-exceptions.c (struct catcher) <exception>: No longer a pointer to volatile exception. Now an exception value. <mask>: Delete field. (exceptions_state_mc_init): Remove all parameters. Adjust. (exceptions_state_mc): No longer pop the catcher here.

Normalize TRY_CATCH exception handling block
This normalizes some exception catch blocks that check for ex.reason to look like this: ~~~ volatile gdb_exception ex; TRY_CATCH (ex, RETURN_MASK_ALL) { ... } if (ex.reason < 0) { ... } ~~~ This is a preparation step for running a script that converts all TRY_CATCH uses to look like this instead: ~~~ TRY { ... } CATCH (ex, RETURN_MASK_ALL) { ... } END_CATCH ~~~ The motivation for that change is being able to reimplent TRY/CATCH in terms of C++ try/catch. This commit makes it so that: - no condition other than ex.reason < 0 is checked in the if predicate - there's no "else" block to check whether no exception was caught - there's no code between the TRY_CATCH (TRY) block and the 'if (ex.reason < 0)' block (CATCH). - the exception object is no longer referred to outside the if/catch block. Note the local volatile exception objects that are currently defined inside functions that use TRY_CATCH will disappear. In cases it's more convenient to still refer to the exception outside the catch block, a new non-volatile local is added and copy to that object is made within the catch block. The following patches should make this all clearer. gdb/ChangeLog: 2015-03-07 Pedro Alves <palves@redhat.com> * amd64-tdep.c (amd64_frame_cache, amd64_sigtramp_frame_cache) (amd64_epilogue_frame_cache): Normal exception handling code. * break-catch-throw.c (check_status_exception_catchpoint) (re_set_exception_catchpoint): Ditto. * cli/cli-interp.c (safe_execute_command): * cli/cli-script.c (script_from_file): Ditto. * compile/compile-c-symbols.c (generate_c_for_for_one_variable): Ditto. * compile/compile-object-run.c (compile_object_run): Ditto. * cp-abi.c (baseclass_offset): Ditto. * cp-valprint.c (cp_print_value): Ditto. * exceptions.c (catch_exceptions_with_msg): * frame-unwind.c (frame_unwind_try_unwinder): Ditto. * frame.c (get_frame_address_in_block_if_available): Ditto. * i386-tdep.c (i386_frame_cache, i386_epilogue_frame_cache) (i386_sigtramp_frame_cache): Ditto. * infcmd.c (post_create_inferior): Ditto. * linespec.c (parse_linespec, find_linespec_symbols): * p-valprint.c (pascal_object_print_value): Ditto. * parse.c (parse_expression_for_completion): Ditto. * python/py-finishbreakpoint.c (bpfinishpy_init): Ditto. * remote.c (remote_get_noisy_reply): Ditto. * s390-linux-tdep.c (s390_frame_unwind_cache): Ditto. * solib-svr4.c (solib_svr4_r_map): Ditto. |
