--- Comment #2 from Pat Haugen <pthaugen at gcc dot gnu.org> --- Created attachment 30402 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=30402&action=edit full .i file The proposed patch fixes the error for the reduced testcase and also fixes the problem for the apsi benchmark, but mesa still hits the same error. Attatching full .i file. Note that -ffast-math is also needed to reproduce this error.
