ced
failing code,
ishttps://gcc.gnu.org/git/?p=3Dgcc.git;a=3Dcommit;h=3Dc496d15954cdeab7f9039=
328f94a6f62cf893d5f
(Aldy Hernandez A singleton irange etc.)
and the first one working again is
https://gcc.gnu.org/git/?p=3Dgcc.git;a=3Dcommit;h=3D1f7e5a7b91862b999aab88e=
e0319052aaf00f0f1

The commit from Vladimir fixed an issue in RTL, but I am not sure what to
conclude from this.=
