            Bug ID: 33226
           Summary: math-vector-fortran.h vs not ffast-math
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: math
          Assignee: unassigned at sourceware dot org
          Reporter: pinskia at gcc dot gnu.org
  Target Milestone: ---
            Target: aarch64 x86_64

This is to record what was reported here:

https://inbox.sourceware.org/libc-alpha/87frl4srm4.fsf@oldenburg3.str.redhat.com/

basically the fortran support for the simd math library is always enabled and
not dependent on -ffast-math unlike the C/C++ side of things.

This is a problem for both aarch64 and x86_64.

This was raised as a question on the #gcc IRC channel by Kyrylo Tkachov because
of a customer who uses IEEE fp module and some fp functions on aarch64.
