this causes ICE
confirmed with gcc -O3 -msse2 -std=gnu99
reduced testcase
typedef unsigned char uint8_t;
typedef struct foo2
{
int offset[4];
uint8_t* ref[4];
} foo2;
int
foo(const foo2 *fooval)
{
uint8_t *source[4] =
{ fooval->ref[0], fooval->ref[1], fooval->ref[2] };
int strides[4] =
{ fooval->offset[0], fooval->offset[1], fooval->offset[2] };
for (int i = 0; i < 4; i++)
{
strides[i] = -strides[i];
source[i] -= strides[i];
}
return source[0];
}
int
main()
{
foo2 fool;
int ret = foo(&fool);
return ret;
}
