--- Comment #3 from cvs-commit at gcc dot gnu.org <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Alan Modra <amo...@sourceware.org>: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=a4b6fadd50968ec6c1b687fe52b88bd11ff734b3 commit a4b6fadd50968ec6c1b687fe52b88bd11ff734b3 Author: Alan Modra <amo...@gmail.com> Date: Tue Sep 1 08:56:22 2015 +0930 ppc64 out-of-line register save/restore functions Don't emit long branch or plt branch stubs to save/restore functions. Copy them instead. The problem is that plt branch stubs currently trash r12, one of the parameters to some of the save/restore functions, and there is no free register available to use instead of r12. 6f20ed8a is prerequisite for this patch. PR 18878 * elf64-ppc.c (ARRAY_SIZE): Define. Use throughout. (enum ppc_stub_type): Add ppc_stub_save_res. (struct map_stub): Add "next" and "needs_save_res". (struct ppc_link_hash_entry): Add "save_res" flag. (struct ppc_link_hash_table): Add "group". (sfpr_define): Add stub_sec param. Define symbol in stub_sec if stub_sec is non-null. Set "save_res". (save_res_funcs): Make file scope, rename from funcs. Adjust uses. (ppc64_elf_adjust_dynamic_symbol): Prohibit plt call to save_res syms. (ppc_build_one_stub): Handle ppc_stub_save_res. (ppc_size_one_stub): Set stub type to ppc_size_one_stub on finding stub for linker defined save_res sym. (group_sections): Init new fields of struct map_stub. (ppc64_elf_size_stubs): Reserve space for save/restore func copy. (ppc64_elf_build_stubs): Copy save/restore funcs to groups. Emit alias syms too. (ppc64_elf_relocate_section): Set destination for ppc_stub_save_res. -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
