Fix PR backtrace/15558 This PR is about an assertion failure in GDB that can be triggered by setting "backtrace limit" to a value that causes GDB to stop unwinding after an inline frame. In this case, an assertion in inline_frame_this_id will trigger: /* We need a valid frame ID, so we need to be based on a valid frame. (...). */ gdb_assert (frame_id_p (*this_id)); Looking at the function: static void inline_frame_this_id (struct frame_info *this_frame, void **this_cache, struct frame_id *this_id) { struct symbol *func; /* In order to have a stable frame ID for a given inline function, we must get the stack / special addresses from the underlying real frame's this_id method. So we must call get_prev_frame. Because we are inlined into some function, there must be previous frames, so this is safe - as long as we're careful not to create any cycles. */ *this_id = get_frame_id (get_prev_frame (this_frame)); we see we're computing the frame id for the inline frame. If this is an inline frame, which is a virtual frame constructed based on debug info, on top of a real stack frame, we should _always_ be able to find where the frame was inlined into, as that ultimately just means peeling off the virtual frames on top of the real stack frame. If there ultimately was no prev (real) stack frame, then we wouldn't have been able to construct the inline frame either, by design. That's what the assertion catches. So we have an inline frame, we should _always_ be able to compute its ID, even if that means bypassing the user backtrace limits to get at the real stack frame's info. The problem is that inline_frame_id calls get_prev_frame, and that takes user backtrace limits into account. Code that wants to bypass the limits calls get_prev_frame_1 instead. Note how get_prev_frame_1 already skips all checks for inline frames: /* If we are unwinding from an inline frame, all of the below tests were already performed when we unwound from the next non-inline frame. We must skip them, since we can not get THIS_FRAME's ID until we have unwound all the way down to the previous non-inline frame. */ if (get_frame_type (this_frame) == INLINE_FRAME) return get_prev_frame_if_no_cycle (this_frame); And note how the related frame_unwind_caller_id function also uses get_prev_frame_1: struct frame_id frame_unwind_caller_id (struct frame_info *next_frame) { struct frame_info *this_frame; /* Use get_prev_frame_1, and not get_prev_frame.

Fix PR backtrace/15558 This PR is about an assertion failure in GDB that can be triggered by setting "backtrace limit" to a value that causes GDB to stop unwinding after an inline frame. In this case, an assertion in inline_frame_this_id will trigger: /* We need a valid frame ID, so we need to be based on a valid frame. (...). */ gdb_assert (frame_id_p (*this_id)); Looking at the function: static void inline_frame_this_id (struct frame_info *this_frame, void **this_cache, struct frame_id *this_id) { struct symbol *func; /* In order to have a stable frame ID for a given inline function, we must get the stack / special addresses from the underlying real frame's this_id method. So we must call get_prev_frame. Because we are inlined into some function, there must be previous frames, so this is safe - as long as we're careful not to create any cycles. */ *this_id = get_frame_id (get_prev_frame (this_frame)); we see we're computing the frame id for the inline frame. If this is an inline frame, which is a virtual frame constructed based on debug info, on top of a real stack frame, we should _always_ be able to find where the frame was inlined into, as that ultimately just means peeling off the virtual frames on top of the real stack frame. If there ultimately was no prev (real) stack frame, then we wouldn't have been able to construct the inline frame either, by design. That's what the assertion catches. So we have an inline frame, we should _always_ be able to compute its ID, even if that means bypassing the user backtrace limits to get at the real stack frame's info. The problem is that inline_frame_id calls get_prev_frame, and that takes user backtrace limits into account. Code that wants to bypass the limits calls get_prev_frame_1 instead. Note how get_prev_frame_1 already skips all checks for inline frames: /* If we are unwinding from an inline frame, all of the below tests were already performed when we unwound from the next non-inline frame. We must skip them, since we can not get THIS_FRAME's ID until we have unwound all the way down to the previous non-inline frame. */ if (get_frame_type (this_frame) == INLINE_FRAME) return get_prev_frame_if_no_cycle (this_frame); And note how the related frame_unwind_caller_id function also uses get_prev_frame_1: struct frame_id frame_unwind_caller_id (struct frame_info *next_frame) { struct frame_info *this_frame; /* Use get_prev_frame_1, and not get_prev_frame. The latter will truncate the frame chain, leading to this function unintentionally returning a null_frame_id (e.g., when a caller requests the frame ID of "main()"s caller. */ next_frame = skip_artificial_frames (next_frame); this_frame = get_prev_frame_1 (next_frame); if (this_frame) return get_frame_id (skip_artificial_frames (this_frame)); else return null_frame_id; } get_prev_frame_1 is currently static in frame.c.

constify struct block in some places This makes some spots in gdb, particularly general_symbol_info, use a "const struct block", then fixes the fallout. The justification is that, ordinarily, blocks ought to be readonly. Note though that we can't add "const" in the blockvector due to block relocation.

out of line functions nested inside inline functions. This patch improves the handling of out-of-line functions nested inside functions that have been inlined. Consider for instance a situation where function Foo_O224_021 has a function Child1 declared in it, which itself has a function Child2 nested inside Child1. After compiling the program with optimization on, Child1 gets inlined, but not Child2. After inserting a breakpoint on Child2, and running the program until reaching that breakpoint, we get the following backtrace: % gdb foo_o224_021 (gdb) break foo_o224_021.child1.child2 (gdb) run [...] Breakpoint 1, foo_o224_021 () at foo_o224_021.adb:28 28 Child1; (gdb) bt #0 0x0000000000402400 in foo_o224_021 () at foo_o224_021.adb:28 #1 0x00000000004027a4 in foo_o224_021.child1 () at foo_o224_021.adb:23 #2 0x00000000004027a4 in foo_o224_021 () at foo_o224_021.adb:28 GDB reports the wrong function name for frame #0. We also get the same kind of error in the "Breakpoint 1, foo_o224_021 () [...]" message. In both cases, the function name should be foo_o224_021.child1.child2, and the parameters should be "s=...". What happens is that the inlined frame handling does not handle well the case where an inlined function is calling an out-of-line function which was declared inside the inlined function's scope. In particular, looking first at the inlined-frame sniffer when applying to frame #0: /* Calculate DEPTH, the number of inlined functions at this location. */ depth = 0; cur_block = frame_block; while (BLOCK_SUPERBLOCK (cur_block)) { if (block_inlined_p (cur_block)) depth++; cur_block = BLOCK_SUPERBLOCK (cur_block); } What happens is that cur_block starts as the block associated to child2, which is not inlined. We shoud be stopping here, but instead, we keep walking the superblock chain, which takes us all the way to Foo_O224_021's block, via Child2's block. And since Child1 was inlined, we end up with a depth count of 1, wrongly making GDB think that frame #0 is an inlined frame. Same kind of issue inside skip_inline_frames. The fix is to stop checking for inlined frames as soon as we see a block corresponding to a function which is not inlined. This is the behavior we now obtain: (gdb) run [...] Breakpoint 1, foo_o224_021.child1.child2 (s=...) at foo_o224_021.adb:9 9 function Child2 (S : String) return Boolean is (gdb) bt #0 0x0000000000402400 in foo_o224_021.child1.child2 (s=...) at foo_o224_021.adb:9 #1 0x00000000004027a4 in foo_o224_021.child1 () at foo_o224_021.adb:23 #2 0x00000000004027a4 in foo_o224_021 () at foo_o224_021.adb:28 gdb/ChangeLog: * inline-frame.c (inline_frame_sniffer, skip_inline_frames): Stop counting inlined frames as soon as an out-of-line function is found. gdb/testsuite/ChangeLog: * gdb.ada/out_of_line_in_inlined.exp: Add run and "bt" tests.

constify struct block in some places This makes some spots in gdb, particularly general_symbol_info, use a "const struct block", then fixes the fallout. The justification is that, ordinarily, blocks ought to be readonly. Note though that we can't add "const" in the blockvector due to block relocation.

constify some blockvector APIs Generally, the blockvector ought to be readonly. So, this patch makes the blockvector const in the symtab, and also changes various blockvector APIs to be const. This patch has a couple of spots that cast away const. I consider these to be ok because they occur in mdebugread and are used while constructing the blockvector. I have added comments at these spots. 2014-06-18 Tom Tromey <tromey@redhat.com> * symtab.h (struct symtab) <blockvector>: Now const. * ada-lang.c (ada_add_global_exceptions): Update. * buildsym.c (augment_type_symtab): Update. * dwarf2read.c (dw2_lookup_symbol): Update. * jit.c (finalize_symtab): Update. * jv-lang.c (add_class_symtab_symbol): Update. * mdebugread.c (parse_symbol, add_block, sort_blocks, new_symtab): Update. * objfiles.c (objfile_relocate1): Update. * psymtab.c (lookup_symbol_aux_psymtabs) (maintenance_check_psymtabs): Update. * python/py-symtab.c (stpy_global_block, stpy_static_block): Update. * spu-tdep.c (spu_catch_start): Update. * symmisc.c (dump_symtab_1): Update. * symtab.c (lookup_global_symbol_from_objfile) (lookup_symbol_aux_objfile, lookup_symbol_aux_quick) (basic_lookup_transparent_type_quick) (basic_lookup_transparent_type, find_pc_sect_symtab) (find_pc_sect_line, search_symbols): Update. * block.c (find_block_in_blockvector): Make "bl" const.

Add some more casts (1/2) Note: I needed to split this patch in two, otherwise it's too big for the mailing list. This patch adds explicit casts to situations where a void pointer is assigned to a pointer to the "real" type. Building in C++ mode requires those assignments to use an explicit cast. This includes, for example: - callback arguments (cleanups, comparison functions, ...) - data attached to some object (objfile, program space, etc) in the form of a void pointer - "user data" passed to some function This patch comes from the commit "(mostly) auto-generated patch to insert casts needed for C++", taken from Pedro's C++ branch. Only files built on x86 with --enable-targets=all are modified, so the native files for other arches will need to be dealt with separately. I built-tested this with --enable-targets=all and reg-tested. To my surprise, a test case (selftest.exp) had to be adjusted. Here's the ChangeLog entry. Again, this was relatively quick to make despite the length, thanks to David Malcom's script, although I don't believe it's very useful information in that particular case... gdb/ChangeLog: * aarch64-tdep.c (aarch64_make_prologue_cache): Add cast(s).

constify struct block in some places This makes some spots in gdb, particularly general_symbol_info, use a "const struct block", then fixes the fallout. The justification is that, ordinarily, blocks ought to be readonly. Note though that we can't add "const" in the blockvector due to block relocation.

out of line functions nested inside inline functions. This patch improves the handling of out-of-line functions nested inside functions that have been inlined. Consider for instance a situation where function Foo_O224_021 has a function Child1 declared in it, which itself has a function Child2 nested inside Child1. After compiling the program with optimization on, Child1 gets inlined, but not Child2. After inserting a breakpoint on Child2, and running the program until reaching that breakpoint, we get the following backtrace: % gdb foo_o224_021 (gdb) break foo_o224_021.child1.child2 (gdb) run [...] Breakpoint 1, foo_o224_021 () at foo_o224_021.adb:28 28 Child1; (gdb) bt #0 0x0000000000402400 in foo_o224_021 () at foo_o224_021.adb:28 #1 0x00000000004027a4 in foo_o224_021.child1 () at foo_o224_021.adb:23 #2 0x00000000004027a4 in foo_o224_021 () at foo_o224_021.adb:28 GDB reports the wrong function name for frame #0. We also get the same kind of error in the "Breakpoint 1, foo_o224_021 () [...]" message. In both cases, the function name should be foo_o224_021.child1.child2, and the parameters should be "s=...". What happens is that the inlined frame handling does not handle well the case where an inlined function is calling an out-of-line function which was declared inside the inlined function's scope. In particular, looking first at the inlined-frame sniffer when applying to frame #0: /* Calculate DEPTH, the number of inlined functions at this location. */ depth = 0; cur_block = frame_block; while (BLOCK_SUPERBLOCK (cur_block)) { if (block_inlined_p (cur_block)) depth++; cur_block = BLOCK_SUPERBLOCK (cur_block); } What happens is that cur_block starts as the block associated to child2, which is not inlined. We shoud be stopping here, but instead, we keep walking the superblock chain, which takes us all the way to Foo_O224_021's block, via Child2's block. And since Child1 was inlined, we end up with a depth count of 1, wrongly making GDB think that frame #0 is an inlined frame. Same kind of issue inside skip_inline_frames. The fix is to stop checking for inlined frames as soon as we see a block corresponding to a function which is not inlined. This is the behavior we now obtain: (gdb) run [...] Breakpoint 1, foo_o224_021.child1.child2 (s=...) at foo_o224_021.adb:9 9 function Child2 (S : String) return Boolean is (gdb) bt #0 0x0000000000402400 in foo_o224_021.child1.child2 (s=...) at foo_o224_021.adb:9 #1 0x00000000004027a4 in foo_o224_021.child1 () at foo_o224_021.adb:23 #2 0x00000000004027a4 in foo_o224_021 () at foo_o224_021.adb:28 gdb/ChangeLog: * inline-frame.c (inline_frame_sniffer, skip_inline_frames): Stop counting inlined frames as soon as an out-of-line function is found. gdb/testsuite/ChangeLog: * gdb.ada/out_of_line_in_inlined.exp: Add run and "bt" tests.
