Bootstrap/test seems to work for Andreas (and for my own internal testing) but
still no results from HJ on gcc-testresults.
Still the testcase is broken, reproducible with a bare cross to ia64-linux
and just -O2 (-fexceptions not needed). More reduced testcase:
typedef struct { unsigned long x[2]; } fpreg;
unsigned long
ffi_call(long i, void **avalue, fpreg *fpr)
{
asm ("stf.spill %0 = %1%P0"
: "=m" (*fpr) : "f"(*(double *)avalue[i]));;
return *(unsigned long *)avalue[i];
}
