--- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Created attachment 57664 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=57664&action=edit Better testcase With the original testcase, the stores to sincosf were optimized away and no longer did the sin->sinf transformation so do it manually.
