thanks
Here's a simple testcase:
// /usr/lib/gcc-snapshot/libexec/gcc/x86_64-linux-gnu/4.8.0/cc1 -fpreprocessed
ice-setf.i -march=corei7 -mcx16 -msahf -mno-movbe -mno-aes -mno-pclmul -mpopcnt

# 1 "ice-setf.i"
int a(int *, unsigned long);
int g(unsigned long);
void r(int, long);
int foo(unsigned long sy, int *x, int i)
{
unsigned long sx = x[0];
if (sy <= sx)
{
unsigned long p = sx * 64;
int m = 0;
int tmp = i ? g(sx) : a(&m, sx);
r(tmp, p);
}
return 0;
}
$ gcc-snapshot -O3 -march=native -std=gnu99 -c ice-setf.i
ice-setf.i: In function 'foo':
ice-setf.i:5:5: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-snapshot/README.Bugs> for instructions.
The ICE is reproducible with -O3, but not with -O2.
I'm trying to submit this upstream, but GCC's bugzilla is currently
down.
