1510 type = signed_type_for_types (TREE_TYPE (chrec_a), TREE_TYPE
(chrec_b));
1511 chrec_a = chrec_convert (type, chrec_a, NULL_TREE);
(gdb) p type
$4 = (tree) 0x0
and we then ICE in
#0 0x000000000064bc08 in fold_convert (type=0x0, arg=0x2aad7d1bb570)

Created an attachment (id=15065)
--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=15065&action=view)
testcase
-O -ftree-vectorize
a cross from x86_64 is enough to trigger the ICE.
reducing.

------- Comment #2 from rguenth at gcc dot gnu dot org 2008-01-31 17:23 -------
Reduced testcase:
typedef long unsigned int size_t;
typedef struct {
long double dat[2];
} gsl_complex_long_double;
typedef struct {
size_t size;
size_t stride;
long double *data;
} gsl_vector_complex_long_double;
void gsl_vector_complex_long_double_set_zero (gsl_vector_complex_long_double *
v)
{
long double * const data = v->data;
const size_t n = v->size;
const size_t stride = v->stride;
const gsl_complex_long_double zero = { { 0.0L,0.0L} } ;
size_t i;
for (i = 0; i < n; i++)
*(gsl_complex_long_double *) (data + 2 * i * stride) = zero;
}
tree.c:signed_or_unsigned_type_for doesn't handle bit_size_type specially
which has TImode and a precision of 68.
