Bug ID: 96974
Summary: [10/11 Regression] ICE in
vect_get_vector_types_for_stmt compiling for SVE
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*-*-*
The reduced testcase:
float a;
int
b ()
{ return __builtin_lrintf(a); }
struct c {
float d;
c() {
for (int e = 0; e < 9; e++)
coeffs[e] = d ? b() : 0;
}
int coeffs[10];
} f;
