Bug ID: 126865
Summary: [17 Regression] ICE at -O2 -march=rv64gcv on riscv64
during GIMPLE pass: slp
Product: gcc
Version: 17.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: xxs_chy at outlook dot com
Target Milestone: ---
Reproducer: https://godbolt.org/z/53r7fsvz3
Reduced case:
#include <stdint.h>
#include <stdlib.h>
uint16_t g2, g24, g11;
_Bool g28_c11;
uint16_t g28()
{
g24 = 10690 / (int16_t)g2;
if (g28_c11) g11 = (int16_t)g28 / 9 + g24;
abort();
}
