James Almer <jamrial at gmail dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- Component|rtl-optimization |tree-optimization --- Comment #5 from James Almer <jamrial at gmail dot com> --- This is a regression introduced by r228599. I'm attaching the output of -save-temps for all three files, the good assembly from r228598 (last good commit) and the bad assembly from r228599. I can't generate a better or simpler testcase, sorry.
