Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |hjl.tools at gmail dot com --- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> --- r0-81134-g3b8dd0716ff7c5 introduced OPT_mno_sse4 handling into ix86_handle_option, but that pre-decodes no- and expects OPT_msse4 to handle it with value == 0. I'm testing a patch to make behavior of -mno-sse4 consistent with all the other flags handled.
