take following example (compile with -O1 -ftree-vectorize -maltivec):
void a(unsigned long long __n, int *__new_start)
{
for (; __n > 0; --__n, ++__new_start)
*__new_start = 0;
}
With the second patch in PR 22368, we get the following error:
pr18425.c: In function 'a':
pr18425.c:2: error: types mismatch in comparsion
long long unsigned intD.6
intD.0
ratio_mult_vf.38D.1726_33 <= 0;
pr18425.c:2: error: types mismatch in comparsion
long long unsigned intD.6
intD.0
prolog_loop_niters.34D.1710_16 <= 0;
pr18425.c:2: internal compiler error: verify_stmts failed
