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.
