Date: Tue, 20 Oct 2020 13:08:41 +0000 [thread overview]
Message-ID: <bug-97502-4@http.gcc.gnu.org/bugzilla/> (raw)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97502
Bug ID: 97502
Summary: [11 Regression] PGO bootstrap failure on s390x-linux
with -march=z13 starting with r11-3426
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: jakub at gcc dot gnu.org
Target Milestone: ---
In profiledbootstrap on s390x-linux --with-arch=z13, I get an ICE during
feedback compilation of s390.c:

Please submit a full bug report,
with preprocessed source if appropriate.
I've managed to reduce it to a small self-contained testcase that fortunately
doesn't even need PGO:
extern char v[54];
void bar (char *);
void
foo (void)
{
int i;
char c[32];
bar (c);
for (i = 0; i < 32; i++)
c[i] = c[i] && !v[i];
bar (c);
}
ICEs the same way with -O3 -march=z13 starting with
r11-3426-g10843f8303509fcba880c6c05c08e4b4ccd24f36
