Bug ID: 110829
Summary: [13/14 Regression] FAIL: gcc.dg/pr56837.c
scan-tree-dump-times optimized "memset ..c, 68,
16384.;" 1
Product: gcc
Version: 13.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: rguenth at gcc dot gnu.org
Target Milestone: ---
After r13-1762-gf9d4c3b45c5ed5 the
_Complex double c[N];
void
fc (void)
{
int i;
for (i = 0; i < N; i++)
c[i] = 747708026454360457216.0 + 747708026454360457216.0i;
}
part of the testcase fails to be recognized as memset since we lower
the complex store to a component-wise store to enable vectorization.
loop distribution doesn't yet handle merging stores as part of
its pattern recognition for memset, memcpy or memmove.
