--- Comment #15 from Jack Howarth <howarth at nitro dot med.uc.edu> 2012-02-23 15:49:06 UTC --- I notice in boehm-gc/include/private/gcconfig.h we are already setting... # ifdef DARWIN # define OS_TYPE "DARWIN" # define DYNAMIC_LOADING # if defined(__ppc64__) # define ALIGNMENT 8 # define CPP_WORDSZ 64 # define STACKBOTTOM ((ptr_t) 0x7fff5fc00000) # define CACHE_LINE_SIZE 64 # ifndef HBLKSIZE # define HBLKSIZE 4096 # endif # else # define ALIGNMENT 4 # define STACKBOTTOM ((ptr_t) 0xc0000000) # endif so I guess we just want to append #ifdef HAVE_PTHREAD_GET_STACKADDR_NP #define STACKBOTTOM (ptr_t)pthread_get_stackaddr_np(pthread_self()) #endif at the end of those lines
