[Bug middle-end/32912] [4.3 Regression] ICE with vector code

[pinskia at gcc dot gnu dot org]

------- Comment #2 from pinskia at gcc dot gnu dot org  2007-07-28 01:15 -------
fold-const.c is causing it at:
10277         /* ~X ^ X is -1.  */

The issue is that we don't fold ~vector_cst at all.

Anyways here is a reduced testcase:
typedef int __m128i __attribute__ ((__vector_size__ (16) ));

typedef __m128i v2d;

v2d rval();
v2d g;
struct A {
   v2d a;
   v2d b;
};
struct B {
   A a;
};
void foo(B);
void bar() {
   v2d l;
   A a={};
   a.a ^= ~a.b;
   a.a ^= ~(v2d) {0,0};
   B c = {a};
   foo(c);
}
