[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri updated this revision to Diff 138385.
lebedev.ri retitled this revision from "[InstCombine] peek through unsigned FP casts for sign-bit compares (PR36682)" to "[InstSimplify] peek through unsigned FP casts for sign-bit compares (PR36682)".
lebedev.ri added a comment.

Rebased ontop of updated tests, moved to InstSimplify.
FIXME: should that code be in some other place, in some other function?
