Bug ID: 97326
Summary: [11 Regression] s390: ICE in do_store_flag after
10843f830350
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: rtl-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: iii at linux dot ibm.com
Target Milestone: ---
The following (minimized from
gcc/testsuite/gcc.target/s390/zvector/autovec-double-signaling-eq.c) produces
an ICE on s390:
build$ cat x.c
long *a;
double *b;
c;
d() {
for (; c; c++)
a[c] = 0 <= b[c] && 0 >= b[c];
}
build$ gcc/cc1 -O3 -march=z15 x.c
during RTL pass: expand
x.c: In function 'd':
