From 45965137bee4946dca3cd99285f2a7afe6b99aeb Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Wed, 5 Mar 2014 19:57:39 +1030 Subject: Support R_PPC64_ADDR64_LOCAL This adds support for "func@localentry", an expression that returns the ELFv2 local entry point address of function "func". I've excluded dynamic relocation support because that obviously would require glibc changes. include/elf/ * ppc64.h (R_PPC64_REL24_NOTOC, R_PPC64_ADDR64_LOCAL): Define. bfd/ * elf64-ppc.c (ppc64_elf_howto_raw): Add R_PPC64_ADDR64_LOCAL entry. (ppc64_elf_reloc_type_lookup): Support R_PPC64_ADDR64_LOCAL. (ppc64_elf_check_relocs): Likewise. (ppc64_elf_relocate_section): Likewise. * Add BFD_RELOC_PPC64_ADDR64_LOCAL. * bfd-in2.h: Regenerate. * libbfd.h: Regenerate. gas/ * config/tc-ppc.c (ppc_elf_suffix): Support @localentry. (md_apply_fix): Support R_PPC64_ADDR64_LOCAL. ld/testsuite/ * ld-powerpc/elfv2-2a.s, ld-powerpc/elfv2-2b.s: New files. * ld-powerpc/elfv2-2exe.d, ld-powerpc/elfv2-2so.d: New files. * ld-powerpc/powerpc.exp: Run new test. elfcpp/ * powerpc.h (R_PPC64_REL24_NOTOC, R_PPC64_ADDR64_LOCAL): Define. gold/ * powerpc.cc (Target_powerpc::Scan::local, global): Support R_PPC64_ADDR64_LOCAL.
