Reduced testcase:
/* { dg-do compile } */
/* { dg-options "-O2 -fprefetch-loop-arrays" } */
void
foo (char *x, unsigned long y, unsigned char *z)
{
unsigned int c[256], *d;
for (d = c + 1; d < c + 256; ++d)
*d += d[-1];
x[--c[z[y]]] = 0;
Hmm. Could this be the char-- bug? Where the front-end/gimplifier does
not promote that to int?
Thanks,
Andrew Pinski
