From 474f0b83bec1cc8d9e8f6cec88764538554b1e3c Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Wed, 11 Jan 2012 09:28:44 +0000 Subject: bfd/ * elf64-ppc.c: Define more insns used in plt call stubs. (ppc64_elf_brtaken_reloc): Assume isa version 2 or above. (ppc64_elf_relocate_section): Likewise. (enum ppc_stub_type): Add ppc_stub_plt_call_r2save. (struct ppc_link_hash_table): Increase size of stub_count array. Add plt_stub_align and plt_thread_safe. (ALWAYS_USE_FAKE_DEP, ALWAYS_EMIT_R2SAVE): Define. (plt_stub_size, plt_stub_pad): New functions. (build_plt_stub): Emit barriers for power7 thread safety. Don't emit needless save of r2. (build_tls_get_addr_stub): Adjust params. (ppc_build_one_stub): Handle ppc_stub_plt_call_r2save and aligning plt stubs. Adjust build_*plt_stub calls. (ppc_size_one_stub): Similarly. (ppc64_elf_size_stubs): Accept plt_thread_safe and plt_stub_align params. Choose default for plt_thread_safe based on existence of calls to thread creation functions. Modify plt_call to plt_call_r2save when no tocsave reloc found. Align tail of stub sections. (ppc64_elf_build_stubs): Align tail of stub sections. Adjust output of stub statistics. (ppc64_elf_relocate_section): Handle ppc_stub_plt_call_r2save. * elf64-ppc.h (ppc64_elf_size_stubs): Update prototype. ld/ * emultempl/ppc64elf.em (PARSE_AND_LIST_PROLOGUE, PARSE_AND_LIST_LONGOPTS, PARSE_AND_LIST_OPTIONS, PARSE_AND_LIST_ARGS_CASES): Handle --{no-,}plt-thread-safe and --{no-,}plt-align. (plt_thread_safe, plt_stub_align): New vars. (gld${EMULATION_NAME}_after_allocation): Pass them to ppc64_elf_size_stubs. Align stub sections according to plt_stub_align. * ld.texinfo: Document new command line options, and an old undocumented option. --- bfd/elf64-ppc.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'bfd/elf64-ppc.h') diff --git a/bfd/elf64-ppc.h b/bfd/elf64-ppc.h index 9026c56f82..2728b275b6 100644 --- a/bfd/elf64-ppc.h +++ b/bfd/elf64-ppc.h @@ -1,5 +1,5 @@ /* PowerPC64-specific support for 64-bit ELF. - Copyright 2002, 2003, 2004, 2005, 2007, 2008, 2010, 2011 + Copyright 2002, 2003, 2004, 2005, 2007, 2008, 2010, 2011, 2012 Free Software Foundation, Inc.
