doesn't always mean you need to define a function symbol on plt code.

2014-07-01Add symbols for global entry stub, and report statsAlan Modra2-5/+42
The undefined function symbols (with non-zero value) on global entry stubs are discarded by objdump when disassembling, so give objdump another symbol to mark the stubs. Also fixes a couple of bugs: - entry_section was set to .opd for ELFv2, which meant a hard error rather than a warning when _start wasn't defined. - global entry stubs were not built if they were the only type of stub in an executable. bfd/ * elf64-ppc.c (ppc_stub_type): Add ppc_stub_global_entry. (struct ppc_link_hash_table): Increase size of stub_count array. (build_global_entry_stubs): Emit symbol on global entry stub. (ppc64_elf_build_stubs): NULL check htab->brlt. Add global entry stub stats. ld/ * emultempl/ppc64elf.em (stub_added): Delete. (gld${EMULATION_NAME}_finish): Call ppc64_elf_build_stubs even when none of the usual stubs have been added. Only change entry_section for ELFv1.
2014-07-01Linker foreign output format support for PowerPC64 ELFv2Alan Modra2-19/+61
Makes the ld srec tests pass. Uses a horrible scan through symbols to find ELF fields for symbol definitions, but the generic linker doesn't offer anything better. Might be slow. Anyway, sane people will link to ELF output then objcopy to convert formats. * elf64-ppc.c (abiversion, set_abiversion): Move earlier. (ppc64_elf_branch_reloc): Adjust addend for ELFv2 local offset. (ppc64_elf_set_toc): Set ".TOC." symbol value when using generic linker. (ppc64_elf_relocate_section): Disable ELFv2 function entry optimisation when --traditional-format.

2014-06-24Don't strip section defining _SDA_BASE_Alan Modra2-3/+22
Prior to 93d1b056 _SDA_BASE_ used to be defined in a linker script output section. Now _SDA_BASE_ is defined in an input section that is subject to being stripped. If the section is stripped we don't output the symbol, which results in --emit-relocs trying to emit relocs with dangling references to _SDA_BASE_. * elf32-ppc.c (ppc_elf_size_dynamic_sections): Arrange to keep .sdata/.sdata2 when _SDA_BASE_/_SDA2_BASE_ should be output for --emit-relocs.

2014-06-13Don't call bfd_link_hash_table_freeAlan Modra51-92/+35
Freeing the linker hash table is a royal pain. It can't be freed before the _bfd_write_contents call in bfd_close, because some target bfd_write_contents functions access the hash table. It can't be freed after bfd_close either, since bfd_alloc memory holding side data structures disappears (PR17047). Clearly the only place it can be freed is actually in bfd_close. This patch doesn't do that, but kills off the existing means of freeing the hash table via a bfd target xvec call. bfd/ PR 17047 * targets.c (BFD_JUMP_TABLE): Delete NAME##_bfd_link_hash_table_free.
