--- Comment #4 from Roger Sayle <roger at nextmovesoftware dot com> --- No, it's not PR 106278 that this PR is similar to (which concerned REG_EQUAL notes and is now fixed), but PR 106303 (which concerns STV converting some mentions of a TImode register/memory, and not others, due to data flow analysis and rtx sharing) which is still open/unresolved. My apologies for the inconvenience, figuring out why the pre-existing STV infrastructure is making some of these counter-intuitive decisions, and what the intended behavior should be, is taking some time. Obviously -mno-stv is a work around.
