--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed.  We're not marking the .MASK_CALL as relevant which is possibly
OK since 'bar' is const.  But we also fail to elide it.

/* For if-conversion of inbranch SIMD clones.  */
DEF_INTERNAL_FN (MASK_CALL, ECF_NOVOPS, NULL)

ECF_NOVOPS is a bit heavy.

We're "removing" scalar stmts in some places but do not care about
not relevant ones.

I have a patch.
