Bug ID: 83847
Summary: [8 Regression] ICE in vectorizable_load, at
tree-vect-stmts.c:7365
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: marxin at gcc dot gnu.org
CC: rsandifo at gcc dot gnu.org
Target Milestone: ---
Starting from r256643 we ICE on:
$ cat ice.i
typedef struct {
struct {
int a;
int b;
} c;
} * d;
typedef struct {
unsigned e;
d f[];
} g;
g h;
d *k;
int i(int j) {
if (j) {
*k = *h.f;
return 1;
}
return 0;
}
int l;
int m;
int n;
d o;
void p() {
for (; i(l); l++) {
n += o->c.a;
m += o->c.b;
}
}
$ gcc -march=bdver4 -O3 -fgnu89-inline ice.i -c
