2016-12-03PowerPC64 dot-symbol compatibility bugfixesAlan Modra12-164/+299
Lots of fixes for the compatibility code that handles linking of -mcall-aixdesc code (or that generated by 12 year old gcc) with current ELFv1 ABI code. 1) A reference to a dot-symbol in an object file wasn't satisfied by a function descriptor in later object files. 2) The as-needed code had bit-rotted; Shared libs now need a strong reference to be counted as needed. 3) --gc-sections involving dot-symbols was broken, needing func_desc_adjust to be run early and lots of other fixes. bfd/ * elf64-ppc.c (struct ppc_link_hash_entry): Delete "was_undefined".

2016-12-02Support an "unlimited" number of user-defined argumentsPedro Alves7-84/+181
New in v2: - A few adjustments / simplifications were possible now that we require C++11: . Use std::unique_ptr to make the user_args_stack std::vector own its elements: static std::vector<std::unique_ptr<user_args>> user_args_stack; . use vector::emplace_back to construct elements directly in the corresponding vectors. . use std::to_string instead of adding a gdb::to_string replacement. - Now includes a test. Docs/NEWS are unchanged from v1 and have already been approved. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ I recently wrote a user-defined command that could benefit from supporting an unlimited number of arguments: http://palves.net/list-active-signal-handlers-with-gdb/ E.g., 'info signal-dispositions 1 2 3 4 5 6 7 8 9 10 11' However, we currently only support up to 10 arguments passed to user-defined commands ($arg0..$arg9). I can't find a good reason for that, other than "old code with hard coded limits". This patch removes that limit and modernizes the code along the way: - Makes the user_args struct a real C++ class that uses std::vector for storage. - Removes the "next" pointer from within user_args and uses a std::vector to maintain a stack instead. - Adds a new RAII-based scoped_user_args_level class to help push/pop user args in the stack instead of using a cleanup. gdb/ChangeLog: 2016-12-02 Pedro Alves <palves@redhat.com> * NEWS: Mention that user commands now accept an unlimited number of arguments. * cli/cli-script.c: Include <vector>.

We're missing a test that makes sure that arguments to user-defined commands are handled correctly when a user-defined command calls another user-defined command / recurses.

2016-12-02Fix PR 20559 - "eval" command and $arg0...$arg9/$argc substitutionPedro Alves9-11/+102
It'd be handy to be able to iterate over command arguments in user-defined commands, in order to support optional arguments ($arg0..$argN). I thought I could make it work with "eval", but alas, it doesn't work currently. E.g., with: define test set $i = 0 while $i < $argc eval "print $arg%d", $i set $i = $i + 1 end end we get: (gdb) test 1 $1 = void (gdb) test 1 2 3 $2 = void $3 = void $4 = void (gdb) The problem is that "eval" doesn't do user-defined command arguments substitution after expanding its own argument. This patch fixes that, which makes the example above work: (gdb) test 1 $1 = 1 (gdb) test 1 2 3 $2 = 1 $3 = 2 $4 = 3 (gdb) New test included, similar the above, but also exercises expanding $argc. I think this is likely to simplify many scripts out there, so I'm adding an example to the manual and mentioning it in NEWS as well. gdb/ChangeLog: 2016-12-02 Pedro Alves <palves@redhat.com> PR cli/20559 * NEWS: Mention "eval" expands user-defined command arguments. * cli/cli-script.c (execute_control_command): Adjust to rename.

2016-12-02PR symtab/16264 - support DW_AT_main_subprogramTom Tromey5-12/+138
This patch adds support for DW_AT_main_subprogram. This is PR symtab/16264. DW_AT_main_subprogram is used to mark a program's entry point. GCC can emit this, and I hope to change the Rust compiler to emit it as well. GDB already supports an older, pre-DWARF 4 convention adopted by FORTRAN compilers, namely to emit DW_AT_calling_convention for the "main" function. However, I think this support in GDB had a small bug, in that it seems to rely on the DW_AT_name being read before DW_AT_calling_convention. This patch fixes this as well. Built and regtested on x86-64 Fedora 24 and the buildbot. New test case included. 2016-12-02 Tom Tromey <tom@tromey.com> PR symtab/16264: * dwarf2read.c (struct partial_die_info) <main_subprogram>: New member.

This patch renames a few trace-related functions, so that they adhere to the de facto standard of naming command entry point functions <command>_command.

The suppress_output field of the mi_ui_out_data structure is never actually set to 1/true. We can therefore remove it, and remove all the if (suppress_output) checks. gdb/ChangeLog: * mi/mi-out.c (mi_ui_out_data) <suppress_output>: Remove. (mi_table_body): Remove suppress_output check. (mi_table_end): Likewise. (mi_table_header): Likewise. (mi_begin): Likewise. (mi_end): Likewise. (mi_field_int): Likewise. (mi_field_string): Likewise. (mi_field_fmt): Likewise.

2016-12-02Always pass a valid section header offset to elf_parse_notesGary Benson2-1/+6
_bfd_elf_make_section_from_shdr calls elf_parse_notes with an offset of -1. This argument is used to calculate Elf_Internal_Note.descpos, which ends up set to a positive but meaningless value. This commit updates _bfd_elf_make_section_from_shdr to pass the correct offset to elf_parse_notes, making Elf_Internal_Note.descpos correct in all cases. bfd/ChangeLog: * elf.c (_bfd_elf_make_section_from_shdr): Pass offset to elf_parse_notes.

2016-12-02[AArch64] Recognize STR instruction in prologueYao Qi2-0/+82
This patch teaches GDB AArch64 backend to recognize STR instructions in prologue, like 'str x19, [sp, #-48]!' or 'str w0, [sp, #44]'. The unit test is added too. gdb: 2016-12-02 Yao Qi <yao.qi@linaro.org> Pedro Alves <palves@redhat.com> * aarch64-tdep.c (aarch64_analyze_prologue): Recognize STR instruction. (aarch64_analyze_prologue_test): More tests.
2016-12-02Add unit test to aarch64 prologue analyzerYao Qi4-9/+150
We don't have an effective way to test prologue analyzer which is highly dependent on instruction patterns in prologue generated by compiler. GDB prologue analyzer may not handle the new sequences generated by new compiler, or may still handle some sequences that generated by very old compilers which are no longer used. The former is a functionality issue, while the latter is a maintenance issue. The input and output of prologue analyzer is quite clear, so it fits for unit test. The input is series of instructions, and the output are 1) where prologue end, 2) where registers are saved. In aarch64, they are represented in 'struct aarch64_prologue_cache'. This patch refactors aarch64_analyze_prologue so it can read instructions from either real target or test harness. In unit test aarch64_analyze_prologue_test, aarch64_analyze_prologue gets instructions we prepared in the test, as the input of prologue analyzer. Then, we checked various fields in 'struct aarch64_prologue_cache'. gdb: 2016-12-02 Yao Qi <yao.qi@linaro.org> Pedro Alves <palves@redhat.com> * aarch64-tdep.c: Include "selftest.h".
