Update.
2004-09-07 Jakub Jelinek <jakub@redhat.com>
* sysdeps/powerpc/powerpc64/configure.in: New file.
* config.h.in (USE_PPC64_OVERLAPPING_OPD): Add.
* configure.in (HAVE_ASM_GLOBAL_DOT_NAME): Remove.
* sysdeps/powerpc/powerpc64/sysdep.h: Formatting.
(OPD_ENT, BODY_LABEL, ENTRY_1, ENTRY_2, END_2, DOT_PREFIX,
BODY_PREFIX): Define.
(ENTRY, DOT_LABEL, END, TRACEBACK, END_GEN_TB, EALIGN): Support
HAVE_ASM_GLOBAL_DOT_NAME or no dot symbols,
USE_PPC64_OVERLAPPING_OPD or never overlapping .opd entries.
* sysdeps/powerpc/powerpc64/dl-machine.h: Include sysdep.h.
(TRAMPOLINE_TEMPLATE, RTLD_START): Use the new sysdep.h macros.
