Compile the following test (reduced from
gcc.dg/torture/fp-int-convert-float128.c) on i686-pc-linux-gnu with -O -mmmx.
It gives an ICE
z.c: In function 'main':
z.c:9: internal compiler error: in cgraph_local_info, at cgraph.c:525
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
I don't know if __float128 is meant to be supported on x86 (provided the user
provides the external library with the relevant functions) or not (it's an
optional part of the x86_64 ABI), but it should not ICE in any case; it should
generate meaningful code or a meaningful error. (-mmmx is required for the
__float128 type to be available on x86.)
extern void abort (void);
extern void exit (int);
int
main (void)
{
static volatile int i;
static volatile __float128 a;
a = i;
if (0 != a)
abort ();
exit (0);
}

------- Comment #1 from pinskia at gcc dot gnu dot org 2005-11-27 01:00 -------
Hmm, 3.3.x did not define __float128 at all. 3.4 and 4.0 did not ICE at -O1
-mmmx but did at -O2 -mmmx (that means it is unit-at-a-time related). I am
going to mark this as a regression as anything to an ICE should be considered a
regression but I am not going to confirm it as I don't know which way this
should be, rejected or accepted.

Crashes are bad: P2 for now. If it turns out that this is "just" an
ICE-on-invalid, then we might downgrade the priority.

Honza, are you going to do something useful with your patch from comment #3?
