2018-07-25Clarify doc for .arch/.cpuThomas Preud'homme2-2/+10
Documentation for .arch and .cpu directives currently says that it accepts the same name as -march/-mcpu command-line options respectively. However it only accept the architecture/CPU part of those options: it does not accept specifying an extension which is done via .arch_extension. This patch clarifies that the extension is not accepted. 2018-07-25 Thomas Preud'homme <thomas.preudhomme@linaro.org> gas/ * doc/c-arm.texi (.arch directive): Clarify that name must not include an extension. (.cpu directive): Likewise.

2018-07-25Enhance powerpc ld -r --relaxAlan Modra7-24/+81
One of the ill effects of ld -r is to mash together sections. That can result in reduced icache performance at runtime due to unexpected movement of code. Another problem is that sections can become too large to link on targets that have limited relative addressing. ld -r --relax attempts to overcome the large section problem for branches by inserting trampolines, but the powerpc support added lots of unnecessary trampolines. This patch trims them somewhat. bfd/ * elf32-ppc.c (ppc_elf_relax_section): Ignore common or undef locals. Avoid trashing toff with added when used as a symbol index.

2018-07-24Set CU language before processing any DIEs (symtab/23010 et al)Keith Seitz2-6/+31
This patch is another attempt at really fixing the multitude of assertions being seen where symbols of one language are being added to symbol lists of another language. In this specific case, the backtrace command (thread apply all bt full) that is looking for the compunit containing the PC of the thread. That calls get_prev_frame several times. This function calls (eventually) dwarf2_frame_prev_register. That eventually ends up calling find_pc_compunit_symtab. In this function (find_pc_sect_compunit_symtab actually), we loop over all compunits, calling the "quick" function dw2_find_pc_sect_compunit_symtab. That function calls dw2_instantiate_symtab to read in all the CU's symbols. Now the fun begins. dw2_do_instantiate_symtab queues the per_cu for reading, using a default "pretend" language of language_minimal with the expectation that this will be set later. The DIEs of this (only queued) CU are then processed. The first DIE is DW_TAG_compile_unit. That's handled by read_file_scope. (Nearly) The first thing read_file_scope does is: get_scope_pc_bounds (die, &lowpc, &highpc, cu); This function loops over the children of the current DIE (a compile_unit), looking for bounds. The first such child is a subprogram, and we attempt to get its bounds. We use dwarf2_attr to get at DW_AT_high_pc. This subprogram has DW_AT_specification set, so dwarf_attr (via follow_die_ref/follow_die_offset) will follow that, but follow_die_offset *also* attempts to load the containing CU for the spec DIE. That spec DIE lives inside a CU that is a partial_unit and has no language attribute. So it simply inherits the language from the CU that elicited the read. [That all happens in follow_die_offset.] The original CU's language is still language_minimal -- we haven't gotten to the line in read_file_scope that actually sets the language yet! And that is the cause of these problems. The call to prepare_one_comp_unit needs to be the *first* thing that is done when reading a CU so that the CU's language can be recorded (and inherited by any referenced partial_units). Since a test reproducer for this has been so elusive, this patch also adds a wrapper function around add_symbol_to_list which asserts when adding a symbol of one language to a list containing symbols of a different language. gdb/ChangeLog: 2017-07-24 Keith Seitz <keiths@redhat.com> PR symtab/23010 * dwarf2read.c (dw2_add_symbol_to_list): New function.

2018-07-24Remove some unnecessary declarations and configuryTom Tromey5-53/+8
configure checks for declarations of free, malloc, and realloc; but the results are only used in a single spot: utils.c. I think these checks are long since obsolete, so this patch removes them. Grepping the entire tree for these HAVE_DECL_ symbols, the only uses of possible interest to gdb come from bfd/sysdep.h; but this is not (nor should be) included by gdb. (And furthermore I think the code there is probably also obsolete.) gdb/ChangeLog 2018-07-24 Tom Tromey <tom@tromey.com> * utils.c (malloc, realloc, free): Don't declare. * configure, config.in: Rebuild. * configure.ac: Don't check for declarations of free, malloc, or realloc.

Just like for their AVX counterparts and CVTSI2S{D,S}, a memory source here is ambiguous and hence - in source files should be qualified with a suitable suffix or operand size specifier (not doing so is an error in Intel mode, and will gain a diagnostic in AT&T mode in the future), - in disassembly should be properly suffixed (the Intel operand size specifiers were emitted correctly already).

2018-07-21Initialize GOT slot for local symbol in non-PIC link.Eric Botcazou2-28/+45
On ARM/VxWorks 7, the R_ARM_TARGET2 relocation used for exception handling is R_ARM_GOT_PREL; moreover in Ada you can define local exceptions. In this case, you may end up with a GOT relocation against a local symbol in a non-PIC link and the ARM linker leaves the GOT slot uninitialized, unlike for example the i386 or the SPARC linkers in the same situation. bfd/ * elf32-arm.c (elf32_arm_final_link_relocate) <R_ARM_GOT32>: Small cleanup for the case of a global symbol that binds locally. Also install a value in the GOT slot in the case of a local symbol in a non-PIC link.
2018-07-20Rename some frame unwind function parametersSimon Marchi3-25/+41
I am currently working with these functions, and though this renaming could help to reason about the code. Some functions take a frame and will return the value associated to that frame, others will return the value associated to the previous frame. Those usually conveniently contain "unwind" in their name, but naming the variable next_frame instead of frame helps remembering which frame we are dealing with. I also included a little typo fix at the top of frame.h. gdb/ChangeLog: * frame.c (frame_register_unwind): Change parameter name. (frame_unwind_register): Likewise. (frame_unwind_register_value): Likewise. (frame_unwind_register_signed): Likewise. (frame_unwind_register_unsigned): Likewise. * frame.h (frame_register_unwind): Likewise. (frame_unwind_register): Likewise. (frame_unwind_register_value): Likewise. (frame_unwind_register_signed): Likewise. (frame_unwind_register_unsigned): Likewise. (frame_unwind_arch): Likewise.
