2017-09-04Let i386_target_description return tdesc_i386_mmxYao Qi4-4/+15
This patch remove the usage of tdesc_i386_mmx in i386-go32-tdep.c, and use i386_target_description to get it instead. gdb: 2017-09-04 Yao Qi <yao.qi@linaro.org> * i386-go32-tdep.c: Include x86-xstate.h. (i386_go32_init_abi): Call i386_target_description. * i386-tdep.c (i386_target_description): Return tdesc_i386_mmx if xcr0 is X86_XSTATE_X87_MASK. * i386-tdep.h (tdesc_i386): Remove the declaration. (tdesc_i386_mmx): Likewise.
2017-09-04Return X86_XSTATE_SSE_MASK instead of 0 in i386fbsd_core_read_xcr0Yao Qi2-2/+7
i386fbsd_core_read_xcr0 reads the value of xcr0 from the corefile. If it fails, returns 0. This makes its caller {i386,amd64}_target_description has to handle this special value. IMO, i386fbsd_core_read_xcr0 should return the default xcr0 in case of error. gdb: 2017-09-04 Yao Qi <yao.qi@linaro.org> * i386-fbsd-tdep.c (i386fbsd_core_read_xcr0): Return X86_XSTATE_SSE_MASK instead of 0.
2017-09-04Use i386_target_description to get tdesc_i386Yao Qi4-8/+14

2017-09-04Use amd64_target_description to get tdesc_amd64Yao Qi10-10/+34
This patch changes amd64-*-tdep.c files to use function amd64_target_description to get the right target description rather than use the variable tdesd_amd64. gdb: 2017-09-04 Yao Qi <yao.qi@linaro.org> * amd64-darwin-tdep.c: Include "x86-xstate.h".

2017-09-04btrace: Store btrace_insn in an std::vectorSimon Marchi5-52/+53

2017-09-03x86-64: Set tlsdesc_plt if GOT_TLS_GDESC_P is trueH.J. Lu6-1/+105
We need to set tlsdesc_plt for x86-64 if GOT_TLS_GDESC_P is true when allocating dynamic relocations so that _bfd_x86_elf_size_dynamic_sections will generate TLSDESC_PLT and TLSDESC_GOT in x86-64 output. bfd/ PR ld/22071 * elfxx-x86.c (elf_x86_allocate_dynrelocs): Set tlsdesc_plt for x86-64 if GOT_TLS_GDESC_P is true. ld/ PR ld/22071 * testsuite/ld-x86-64/pr22071.d: New file. * testsuite/ld-x86-64/pr22071.s: Likewise. * testsuite/ld-x86-64/x86-64.exp: Run pr22071.

2017-09-03Make target_waitstatus_to_string return an std::stringSimon Marchi10-70/+71
A quite straightforward change. It does "fix" leaks in record-btrace.c, although since this is only used in debug printing code, it has no real world impact. gdb/ChangeLog: * target/waitstatus.h (target_waitstatus_to_string): Change return type to std::string. * target/waitstatus.c (target_waitstatus_to_string): Return std::string. * target.h (target_waitstatus_to_string): Remove declaration. * infrun.c (resume, clear_proceed_status_thread, print_target_wait_results, do_target_wait, save_waitstatus, stop_all_threads): Adjust. * record-btrace.c (record_btrace_wait): Adjust. * target-debug.h (target_debug_print_struct_target_waitstatus_p): Adjust. gdb/gdbserver/ChangeLog: * linux-low.c (linux_wait_1): Adjust. * server.c (queue_stop_reply_callback): Adjust.

2017-09-02x86: Add _bfd_x86_elf_size_dynamic_sectionsH.J. Lu4-815/+483
elf_i386_size_dynamic_sections and elf_x86_64_size_dynamic_sections are very similar, except for the followings: 1. elf_i386_size_dynamic_sections checks GOT_TLS_IE and GOT_TLS_IE_BOTH. elf_x86_64_size_dynamic_sections checks only GOT_TLS_IE. Since GOT_TLS_IE_BOTH is never true for x86-64, it is OK to check GOT_TLS_IE for both i386 and x86-64. 2, x86-64 sets tlsdesc_plt, but i386 doesn't. We set tlsdesc_plt only if target_id == X86_64_ELF_DATA. 3. x86-64 has if (s != htab->elf.srelplt) s->reloc_count = 0; and i386 has s->reloc_count = 0; i386 did have if (s != htab->srelplt) s->reloc_count = 0; in the original commit: commit 67a4f2b710581acc83afecff55424af285ecbc28 Author: Alexandre Oliva <aoliva@redhat.com> Date: Wed Jan 18 21:07:51 2006 +0000 But it was removed by commit 5ae0bfb60a576344d7f701605346282c1144499e Author: Richard Sandiford <rdsandiford@googlemail.com> Date: Tue Feb 28 07:16:12 2006 +0000 bfd/ * elf32-i386.c (elf_i386_link_hash_table): Add next_tls_desc_index.

(elf_i386_finish_dynamic_symbol): Put R_386_IRELATIVE after R_386_JUMP_SLOT. changed it back to use reloc_count again. So it is correct to use if (s != htab->elf.srelplt) s->reloc_count = 0; for both i386 and x86-64 now. 4. i386 and x86-64 use different DT_XXXs. They are handled by adding them to elf_x86_link_hash_table.

2017-09-02LTO rescan archivesAlan Modra4-7/+103
ld ought to be more clever about where it puts LTO recompiled objects. Ideally the recompiled objects ought to be ordered to the same place their IR objects were, and files extracted from archives on the second pass ought to go in the same place as they would if extracted on the first pass. This patch addresses the archive problem. Without this fix, objects extracted from archives might be placed after the crt files intended to go at the end of an executable or shared library, possibly causing exception handling failures. * ldlang.h (lang_input_statement_type): Expand comments.
