PowerPC64 __tls_get_addr_desc
This implements register saving and restoring in the __tls_get_addr
call stub, so that when glibc supports the optimized tls call stub gcc
can generate code that assumes only r0, r12 and of course r3 are
changed on a __tls_get_addr call. When gcc expects __tls_get_addr
calls to preserve registers the call will be to __tls_get_addr_desc,
which will be translated by the linker to a call to __tls_get_addr_opt.
bfd/
* elf64-ppc.h (struct ppc64_elf_params): Add no_tls_get_addr_regsave.
* elf64-ppc.c (struct ppc_link_hash_table): Add tga_desc and
tga_desc_fd.
(is_tls_get_addr): Match tga_desc and tga_desc_df too.
(STDU_R1_0R1, ADDI_R1_R1): Define.
(tls_get_addr_prologue, tls_get_addr_epilogue): New functions.
(ppc64_elf_tls_setup): Set up tga_desc and tga_desc_fd. Indirect
tga_desc_fd to opt_fd, and tga_desc to opt. Set
no_tls_get_addr_regsave.
(branch_reloc_hash_match): Add hash3 and hash4.
(ppc64_elf_tls_optimize): Handle tga_desc_fd and tga_desc too.
(ppc64_elf_size_dynamic_sections): Likewise.
(ppc64_elf_relocate_section): Likewise.
(plt_stub_size, build_plt_stub): Likewise. Size regsave
__tls_get_addr stub.
(build_tls_get_addr_stub): Build regsave __tls_get_addr stub and
eh_frame.
(ppc_size_one_stub): Handle tga_desc_fd and tga_desc too. Size
eh_frame for regsave __tls_get_addr.
gas/
* config/tc-ppc.c (parse_tls_arg): Handle tls arg for
__tls_get_addr_desc and __tls_get_addr_opt.
ld/
* emultempl/ppc64elf.em (ppc64_opt, PARSE_AND_LIST_LONGOPTS),
(PARSE_AND_LIST_OPTIONS, PARSE_AND_LIST_ARGS_CASES): Support
--tls-get-addr-regsave and --no-tls-get-addr-regsave.
(params): Init new field.
* ld.texi (--tls-get-addr-regsave, --no-tls-get-addr-regsave):
Document.
