Bug ID: 114691
Summary: [11/12/13/14 Regression] Bogus ignoring loop
annotation warning
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org

Depends on: 114409
Target Milestone: ---
+++ This bug was initially created as a clone of Bug #114409 +++
As the PR114409 initially reported P1 bug is now fixed, I'm cloning it for the
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114409#c10 regression.
int foo (int);
void
qux (int x)
{
#pragma GCC ivdep
while (int y = foo (x))
++y;
}
With no options this didn't emit any warnings e.g. in r200000 (i.e. in GCC
4.9), while
it emits
pr114409-2.C:7:24: warning: ignoring loop annotation
warning in r220000 (i.e. in GCC 5+).
Can't bisect easily, because in various revisions in between it ICEs on
ANNOTATE_EXPR.
