Bug ID: 102572
Summary: ICE for skx in vect_build_gather_load_calls, at
tree-vect-stmts.c:2835
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: vsevolod.livinskij at frtk dot ru
Target Milestone: ---
Reproducer:
int a, b, c, f;
void g(bool h, int d[][5]) {
for (short i = f; i; i += 1) {
a = h && d[0][i];
for (int j = 0; j < 4; j += c)
b = 0;
}
}
Error:
