Update.
2004-10-25 Kaz Kojima <kkojima@rr.iij4u.or.jp> * sysdeps/sh/dl-machine.h: Include sysdep.h. (ELF_MACHINE_RUNTIME_TRAMPOLINE): Add CFI directives. (elf_machine_runtime_setup): Add always_inline attribute. (_dl_start_user): Pass the correct environ. (elf_machine_rela): Replace static inline by auto inline, add always_inline attribute. (elf_machine_rela_relative): Likewise. (elf_machine_lazy_rel): Likewise.
