The following code snippet causes an ICE since GCC 4.0.2
(and in GCC 3.4.5, 3.4.6):
=============================================
int __attribute__((vector_size(8))) x;
void foo()
{
~x;
}
=============================================
bug.cc: In function 'void foo()':
bug.cc:5: internal compiler error: in perform_integral_promotions, at
cp/typeck.c:1575
Please submit a full bug report, [etc.]
The code was rejected before:
bug.cc: In function `void foo()':
bug.cc:5: error: wrong type argument to bit-complement
However, it is accepted by the C frontend since GCC 3.3.
