------- Comment #1 from pinskia at gcc dot gnu dot org 2006-09-14 23:07 -------
The C++ front-end produces:
a:
.long 1
.long 2
.zero 8
While the C front-end does not have .zero there.

------- Comment #2 from pinskia at gcc dot gnu dot org 2006-09-15 05:35 -------
3.2.3 on x86 with -msse (since we did not have generic vectors until 3.3)
works.
And 3.3.3 fails (even with -msse).
Note a better testcase is something like:
#include <stdlib.h>
__attribute__((vector_size(16))) int a = {1, 2};
int c = 1;
__attribute__((vector_size(16))) int b = {1, 2};
int main(void)
{
int *b = (int*)&a;
if (b[0] != 1)
abort ();
if (b[1] != 2)
abort ();
if (b[2] != 0)
abort ();
if (b[3] != 0)
abort ();
return 0;
}

------- Comment #3 from pinskia at gcc dot gnu dot org 2006-09-17 01:23 -------
This was caused by:
2003-04-01 Aldy Hernandez <aldyh@redhat.com>
* testsuite/gcc.c-torture/execute/simd-3.c: New.
* expr.c (expand_expr): Handle VECTOR_CST.
(const_vector_from_tree): New.
* varasm.c (output_constant): Handle VECTOR_CST.
* c-typeck.c (digest_init): Build a vector constant from a
VECTOR_TYPE.
Specificly the digest_init change, though output_constant does not check make
sure we have the right number of elements either. build_vector does not
either.
