This patch allows the user to override powerpc64-ld's default for providing linker generated register save and restore functions as used by gcc -Os code. Normally these are not provided by ld -r, so Linux kernel modules have needed to include their own copies. bfd/ * elf64-ppc.h (struct ppc64_elf_params): Add save_restore_funcs. * elf64-ppc.c (ppc64_elf_func_desc_adjust): Use it to control provision of out-of-line register save/restore routines. ld/ * emultempl/ppc64elf.em (params): Init new field. (ppc_create_output_section_statements): Set params.save_restore_funcs default. (PARSE_AND_LIST_*): Add support for --save-restore-funcs and --no-save-restore-funcs.
