2014-11-11ld -r abort in _bfd_elf_write_section_eh_frameAlan Modra2-1/+11
Turning on .eh_frame processing for ld -r resulted in systemtap tickling a ld bug. Triggered by the zero terminator not being added to .eh_frame in a separate file as it usually is (crtend.o), but instead being present in the last .eh_frame section along with CIEs and FDEs. The 4-byte terminator makes the section size check fail on 64-bit targets. * elf-eh-frame (_bfd_elf_write_section_eh_frame): Adjust section size check to account for possible zero terminator.

2014-10-28Add gcc-4.9 libgomp symbols requiring --plt-thread-safe for power7Alan Modra4-0/+23
powerpc64 ld builds plt call stubs with a read barrier to provide thread safety on lazy plt updates, necessary on multi-threaded apps with power7 or later weakly ordered memory. gcc-4.9 libgomp introduced more functions that could call pthread_create, which means we have more functions that if referenced in an executable should cause a default of --plt-thread-safe. bfd/ * elf64-ppc.c (ppc64_elf_size_stubs): Add gcc-4.9 libgomp functions to thread_starter. gold/ * powerpc.cc (do_relax): Add gcc-4.9 libgomp functions to thread_starter.
2014-10-28PowerPC64 ELFv1 function symbol definition vs LTO and discarded sectionsAlan Modra2-43/+69
When functions are emitted in comdat groups, global symbols defined in duplicates of the group are treated as if they were undefined. That prevents the symbols in the discarded sections from affecting the linker's global symbol hash table or causing duplicate symbol errors. Annoyingly, when gcc emits a function to a comdat group, it does not put *all* of a function's code and data in the comdat group. Typically, constant tables, exception handling info, and debug info are emitted to normal sections outside of the group, which is a perennial source of linker problems due to the special handling needed to deal with the extra-group pieces that ought to be discarded. In the case of powerpc64-gcc, the OPD entry for a function is not put in the group. Since the function symbol is defined on the OPD entry this means we need to handle symbols in .opd specially. To see how this affects LTO in particular, consider the linker testcase PR ld/12942 (1). This testcase links an LTO object file pr12942a.o with a normal (non-LTO) object pr12942b.o. Both objects contain a definition for _Z4testv in a comdat group. On loading pr12942a.o, the linker sees a comdat group (actually linkonce section) for _Z4testv and a weak _Z4testv defined in the IR. On loading pr12942b.o, the linker sees the same comdat group, and thus discards it. However, _Z4testv is a weak symbol defined in .opd, not part of the group, so this weak symbol overrides the weak IR symbol. On (re)loading the LTO version of pr12942a.o, the linker sees another weak _Z4testv, but this one does not override the value we have from pr12942b.o. The result is a linker complaint about "`_Z4testv' ... defined in discarded section `.group' of tmpdir/pr12942b.o". * elf64-ppc.c (ppc64_elf_add_symbol_hook): If function code section for function symbols defined in .opd is discarded, let the symbol appear to be undefined. (opd_entry_value): Ensure the result section is that for the function code section in the same object as the OPD entry.
2014-10-28Fix PR17493, attempted output of *GAS `reg' section* symbolAlan Modra5-8/+22
The write.c change is to make gas report an error if reg_section symbols should leak in future. The tc-i386.c change is the real fix.
