Bug ID: 111136
Summary: ICE in RISC-V test case since r14-3441-ga1558e9ad85693
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: rdapp at gcc dot gnu.org
Target Milestone: ---
Target: riscv
The following RISC-V test case ICEs since r14-3441-ga1558e9ad85693
(mask_gather_load-11.c)
#define uint8_t unsigned char
void
foo (uint8_t *restrict y, uint8_t *restrict x,
uint8_t *index,
uint8_t *cond)
{
for (int i = 0; i < 100; ++i)
{
if (cond[i * 2])
y[i * 2] = x[index[i * 2]] + 1;
if (cond[i * 2 + 1])
y[i * 2 + 1] = x[index[i * 2 + 1]] + 2;
}
}
I compiled with
build/gcc/cc1 -march=rv64gcv -mabi=lp64 -O3
--param=riscv-autovec-preference=scalable mask_gather_load-11.c
mask_gather_load-11.c: In function 'foo':
