[Bug c/29736] New: [4.0/4.1/4.2/4.3 regression] ICE on duplicate vector attribute

[reichelt at gcc dot gnu dot org]

The following invalid code snippet triggers an ICE since GCC 4.0.2:

=================================================
int __attribute__((vector_size(8),vector_size(8))) v;

void foo()
{
    v = v + v;
}
=================================================

bug.c: In function 'foo':
bug.c:5: internal compiler error: in same_scalar_type_ignoring_signedness, at
c-common.c:6379
Please submit a full bug report, [etc.]

Can't reproduce this with 4.3, 4.2 or 4.1-RH, getting
error: invalid vector type for attribute 'vector_size'
error and no ICE, with both C and C++ FEs.

Ah, -m32 does the trick, it doesn't fail on x86_64-linux with -m64 or -m32
-msse2.

[Bug c/29736] [4.0 regression] ICE on duplicate vector attribute

[reichelt at gcc dot gnu dot org]

------- Comment #7 from reichelt at gcc dot gnu dot org  2007-02-03 20:53 -------
Won't be fixed on the 4.0 branch.
Fixed in GCC 4.1.2.
