            Bug ID: 17088
           Summary: fallback fesetenv / feupdateenv should give errors for
                    FE_NOMASK_ENV
           Product: glibc
           Version: 2.19
            Status: NEW
          Severity: normal
          Priority: P2
         Component: math
          Assignee: unassigned at sourceware dot org
          Reporter: jsm28 at gcc dot gnu.org

The fallback implementations of fesetenv and feupdateenv should give errors if
passed FE_NOMASK_ENV (if it's defined and some exceptions are defined, e.g. for
MIPS soft-float).

commit 831b9896d8e957580591a3cbe11dcd5ac6743ba2
Author: Joseph Myers <joseph@codesourcery.com>

    Fix fallback fesetenv and feupdateenv on FE_NOMASK_ENV (bug 17088).

    This patch fixes bug 17088, fallback fesetenv and feupdateenv not
    giving an error for an FE_NOMASK_ENV argument when it requires traps
    to be enabled.  (This is the bug tested for by test-fenv-return.c.)

    Tested mips64 soft-float.

        [BZ #17088]
        * math/fesetenv.c (__fesetenv)
        [FE_NOMASK_ENV && FE_ALL_EXCEPT != 0]: Return 1 for FE_NOMASK_ENV.
        * math/feupdateenv.c (__feupdateenv)
        [FE_NOMASK_ENV && FE_ALL_EXCEPT != 0]: Likewise.
