--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The original ICE is with -flto, but modified testcase:
/* PR c++/71077 */
/* { dg-do compile { target { i?86-*-* x86_64-*-* } } } */
/* { dg-options "-O3 -march=core-avx2" } */
int *a;
static int b, c, d, e;
static inline int sched_analyze(void) {
for (; b; b++) {
c = 0;
for (; c < 32; c++)
if (b & 1 << c)
a[b + c] = d;
}
return 0;
}
static inline void schedule_insns(void) { e = sched_analyze(); }
int main(void) { schedule_insns(); }
ICEs with the last patch even without -flto.
