--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed. We canonicalize x < 11 to x <= 10 and on GIMPLE we don't have CC
flags and thus we cannot combine the two compares (we could maybe invent
switch (x CC_EXPR 11) { case LT: .. }). So _maybe_ compare elimination on RTL
is needed to do the job here.
