Bug ID: 117554
Summary: [15 Regression] ICE building 538.imagick_r with SVE
-msve-vector-bits=128
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Keywords: aarch64-sve, 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 imagick ICEs on aarch64 SVE. The reduced testcase is:
typedef short a;
typedef struct {
a b, c;
} d;
int e;
d *f;
long g;
char h;
void i(char *j, char *k) { *k = *j; }
void l() {
char *m;
for (; g; g++) {
i(m, &h);
f->c = h;
f->b = f->c;
m += e;
f++;
}
}
Command-line: -O2 -march=armv8.2-a+sve -msve-vector-bits=128
