Re: IA64 versus effective stack limit

I seem to be getting plausible results from this bit of crockery:


#include <asm/ia64regs.h>

static __inline__ void *
get_bsp(void)
{ void *ret;
#ifndef __INTEL_COMPILER __asm__ __volatile__(                      ";;\n    mov %0=ar.bsp\n"
:"=r"(ret));
#else ret = (void *) __getReg(_IA64_REG_AR_BSP);
#endif return ret;
}


I'll clean this up and commit, assuming it actually fixes the problem.
