--- Comment #19 from Uroš Bizjak <ubizjak at gmail dot com> --- (In reply to Jakub Jelinek from comment #18) > Created attachment 40808 [details] > gcc7-pr70465-2.patch > > Now actually working patch for this testcase. +/* { dg-do compile { target ia32 } } */ +/* { dg-options "-Ofast -mfpmath=387 -fomit-frame-pointer" } */ Is there a reason that this test (and the previous one) is limited to ia32 only? -mfpmath=387 should give the same result on x86_64, too.
