2014-12-23Correct logic for "defined by object"Alan Modra2-4/+8
The old code missed testing bfd_link_hash_undefweak, and wrongly excluded bfd_link_hash_common symbols.

2014-12-20gdb/17394: cannot put breakpoint only in selected ASM file.Mihail-Marian Nistor7-24/+644
This patch fixes a problem when trying to insert a breakpoint on a specific symbol defined in a specific file, eg: break foo.c:func This currently works for files in C/C++/Ada, etc, but doesn't always work for Asm files. Analysis of the problem showed that this related to a limitation in gas, which does not generate debug info for functions/ symbols. Thus, we have a symtab for the file ("info sources" shows the file), but it contains no symbols. When find_linespec_symbols is called in linespec_parse_basic, it calls find_function_symbols, which uses add_matching_symbols_to_info to collect all matching symbols. That function does [pardon any mangled formatting]: for (ix = 0; VEC_iterate (symtab_ptr, info->file_symtabs, ix, elt); ++ix) { if (elt == NULL) { iterate_over_all_matching_symtabs (info->state, name, VAR_DOMAIN, collect_symbols, info, pspace, 1); search_minsyms_for_name (info, name, pspace); } else if (pspace == NULL || pspace == SYMTAB_PSPACE (elt)) { /* Program spaces that are executing startup should have been filtered out earlier. */ gdb_assert (!SYMTAB_PSPACE (elt)->executing_startup); set_current_program_space (SYMTAB_PSPACE (elt)); iterate_over_file_blocks (elt, name, VAR_DOMAIN, collect_symbols, info); } } This iterates over the symtabs. In the failing use case, ELT is non-NULL (points to the symtab for the .s file), so it calls iterate_over_file_blocks. Herein is where the problem exists: it is assumed that if NAME exists, it must exist in the given symtab -- a reasonable assumption for "normal" (non-asm) cases. It never searches minimal symbols (or in the global default symtab). This patch fixes the problem by doing so. It is important to note that iterating over minsyms is fairly expensive, so this patch only adds that extra search if the language is language_asm and iterate_over_file_blocks returns no symbols. gdb/ChangeLog: 2014-12-20 Keith Seitz <keiths@redhat.com> Mihail-Marian Nistor <mihail.nistor@freescale.com> PR gdb/17394 * linespec.c (struct collect_minsyms): Add new member `symtab'.

2014-12-20Change SometimesInlineFunction to "return i * i * 3;"H.J. Lu2-1/+7
The debug_msg test has 2 implementations of SometimesInlineFunction: int SometimesInlineFunction(int i) { return i; } int SometimesInlineFunction(int i) { return i * i; } and One Definition Rule (ODR) violation detection expects they will be compiled into functions of different sizes. Hower, on x86, GCC 4.7 and newer compile them into functions of the same size and ODR violation detection test fails. This patch changes int SometimesInlineFunction(int i) { return i; } to int SometimesInlineFunction(int i) { return i * i * 3; } so that it will be compiled into a function of larger size.

2014-12-18MIPS: Provide FPU info and decode FCSR in `info float'Yao Qi4-1/+115
This patch is the V2. V1 can be found in https://sourceware.org/ml/gdb-patches/2012-05/msg00938.html V2 is to address Joel's comment <https://sourceware.org/ml/gdb-patches/2012-06/msg00289.html> about keeping dumping floating point registers. Additionally, command 'info float' prints bits on nan2008 and abs2008. ------------------------------------------------------------------ The change below provides a MIPS-specific handler for the: (gdb) info float command. It provides information about the FPU type available (if any), the FPU register width, and decodes the CP1 Floating Point Control and Status Register (FCSR): (gdb) print /x $fsr $1 = 0xff83ffff (gdb) info float fpu type: double-precision reg size: 32 bits cond : 0 1 2 3 4 5 6 7 cause : inexact uflow oflow div0 inval unimp mask : inexact uflow oflow div0 inval flags : inexact uflow oflow div0 inval rounding: -inf flush : zero One point to note about CP1.FCSR are the non-standard Flush-to-Nearest and Flush-Override bits. They are not a part of the MIPS architecture and take two positions reserved for an implementation-dependent use in the architecture. They are present in all the FPU implementations made by MIPS Technologies since the spin-off from SGI. I haven't been able to track down a single other MIPS FPU implementation that would make any use of these bits and they are required to be hardwired to zero by the architecture specification if unimplemented. Therefore I think it makes sense to report them in the current way. GDB has no guaranteed access to the CP0 Processor Identification (PRId) register to validate this feature properly and the ID information stored in the CP1 Floating Point Implementation Register (FIR) is from my experience not reliable enough (there's no Company ID available there for once unlike in CP0.PRId and Processor ID is not guaranteed to be unique). As a side note we should probably dump CP1.FIR information as well, as there's useful stuff indicating some FPU features there. That's material for another change however. gdb/ 2014-12-18 Nigel Stephens <nigel@mips.com> Maciej W. Rozycki <macro@codesourcery.com> * mips-tdep.c (print_fpu_flags): New function.

2014-12-17value_maybe_namespace_elt: Remove redundant call to lookup_static_symbol.Doug Evans2-9/+5
Anytime you can remove a symbol lookup that loops over all objfiles is A Good Thing. The call to lookup_static_symbol in valops.c:value_maybe_namespace_elt is redundant with this call in cp_lookup_nested_symbol: /* Now search all static file-level symbols. We have to do this for things like typedefs in the class. We do not try to guess any imported namespace as even the fully specified namespace search is already not C++ compliant and more assumptions could make it too magic. */ size = strlen (parent_name) + 2 + strlen (nested_name) + 1; concatenated_name = alloca (size); xsnprintf (concatenated_name, size, "%s::%s", parent_name, nested_name); sym = lookup_static_symbol (concatenated_name, VAR_DOMAIN); if (sym != NULL) return sym; Earlier in value_maybe_namespace_elt we do this: sym = cp_lookup_symbol_namespace (namespace_name, name, get_selected_block (0), VAR_DOMAIN); That sequence goes like: value_maybe_namespace_elt -> cp_lookup_symbol_namespace -> cp_lookup_symbol_in_namespace -> lookup_symbol_file -> cp_lookup_nested_symbol -> lookup_static_symbol The call was added in commit 41f62f3939b1c69e68ef5652feb44fef90eb85c9. https://sourceware.org/ml/gdb-patches/2010-06/msg00663.html With a part 2 here: https://sourceware.org/ml/gdb-patches/2010-06/msg00664.html At the time the call to lookup_static_symbol (spelled lookup_static_symbol_aux at the time) was needed. However, this patch, 8dea366bbed7986295681c101dcfbd35aeb6dfc4, https://sourceware.org/ml/gdb-patches/2012-11/msg00387.html augmented lookup_symbol_file to call cp_lookup_nested_symbol and introduced the redundancy. It's kinda buried, so it's totally not unexpected that this happened. gdb/ChangeLog: * valops.c (value_maybe_namespace_elt): Remove redundant call to lookup_static_symbol.

2014-12-17Make buildsym set-up/tear-down more consistent, and document it.Doug Evans4-76/+180
gdb/ChangeLog: * buildsym.c: Add comments describing how the buildsym machinery is used by the various file formats. (really_free_pendings): Enhance function comment. See pending_macros to NULL. Simplify resetting pending_addrmap. Call free_buildsym_compunit. (free_buildsym_compunit): Set current_subfile to NULL. (prepare_for_building): New function. (start_symtab): Call it. Remove call to set_last_source_file. (restart_symtab): New arg "cust". All callers updated. Simplify, call prepare_for_building. Re-initialize buildsym_compunit. (reset_symtab_globals): Enhance function comment. Set local_symbols, file_symbols, global_symbols to NULL. Set pending_macros to NULL. Simplify resetting pending_addrmap. Call free_buildysym_compunit. (end_symtab_without_blockvector): Delete. All callers updated. (end_symtab_with_blockvector): Remove redundant call to free_buildsym_compunit. (augment_type_symtab): Remove arg "cust". All callers updated. (buildsym_init): Remove resetting of free_pendings, file_symbols, global_symbols, pending_blocks, pending_macros. Instead make handling consistent with pending_addrmap: Assert value was reset at end of previous symtab building. Initialize context_stack here.
