Some day the backend may handle instruction-level fast math flags and make this transform unnecessary, but it's still better practice to use the canonical representation of fneg when possible (use a -0.0). This is a partial fix for PR20870 ( http://llvm.org/bugs/show_bug.cgi?id=20870 ). See also http://reviews.llvm.org/D6723. Differential Revision: http://reviews.llvm.org/D6731 llvm-svn: 225050 |
