            Bug ID: 19181
           Summary: [i386/x86_64] fesetenv (FE_DFL_ENV), fesetenv
                    (FE_NOMASK_ENV) do not clear SSE exceptions
           Product: glibc
           Version: 2.22
            Status: NEW
          Severity: normal
          Priority: P2
         Component: math
          Assignee: unassigned at sourceware dot org
          Reporter: jsm28 at gcc dot gnu.org
  Target Milestone: ---
            Target: i?86-*-* x86_64-*-*

The i386 and x86_64 versions of fesetenv, when called with FE_DFL_ENV or
FE_NOMASK_ENV as argument, do not clear SSE exceptions raised in MXCSR.  These
arguments should, like other fenv_t values, represent the whole of the
floating-point state, so such exceptions should be cleared.  (Discovered while
working on bug 16068.)
