2006-06-02 Geoffrey Keating <geoffk@apple.com> * config/rs6000/host-darwin.c (sigaltstack): Protect prototype with HAVE_DECL_SIGALTSTACK. (MC_FLD): New. (segv_handler): Use MC_FLD. * configure.ac: Check for a sigaltstack declaration. Compute HAS_MCONTEXT_T_UNDERSCORES on Darwin. * configure: Regenerate. * config.in: Regenerate. Index: boehm-gc/ChangeLog 2006-06-02 Geoffrey Keating <geoffk@apple.com> * configure.ac: Define HAS_PPC_THREAD_STATE_R0, HAS_PPC_THREAD_STATE___R0, HAS_PPC_THREAD_STATE64_R0, HAS_PPC_THREAD_STATE64___R0, HAS_I386_THREAD_STATE_EAX, HAS_I386_THREAD_STATE___EAX. * configure: Regenerate. * include/gc_config.h.in: Regenerate. * darwin_stop_world.c (PPC_RED_ZONE_SIZE): Use standard Darwin macro names to determine value. (THREAD_STATE): New. (THREAD_FLD): New. (GC_push_all_stacks): Use THREAD_STATE and THREAD_FLD in both versions. From-SVN: r114339
