Bug ID: 98535
Summary: [11 Regression] ICE in
operands_scanner::get_expr_operands(tree_node**, int)
building 538.imagick_r
Product: gcc
Version: unknown
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: ktkachov at gcc dot gnu.org
Target Milestone: ---
Target: aarch64
Building 538.imagick_r from SPEC2017 ICEs on aarch64 with -O3 -mcpu=neoverse-v1
(SVE-enabled)
A reduced testcase is:
typedef short a;
typedef struct {
a b, c, d, e;
} f;
f *g;
long h;
void
i() {
f j;
for (; h; h++)
*g++ = j;
}
during GIMPLE pass: vect
foo.c: In function 'i':
foo.c:12:1: internal compiler error: Segmentation fault
12 | i() {
| ^
