commit 775e99641eca25a0dc9049253fe12b02c568f97a
Author: Joseph Myers <joseph@codesourcery.com>

    Use soft-fp fma for no-FPU ColdFire (bug 13304).

    Systems without floating-point exceptions and rounding modes should
    use the soft-fp versions of fmaf and fma, not the sysdeps/ieee754
    versions that rely on setting rounding to zero and testing for the
    "inexact" exception; this has been noted on
    <https://sourceware.org/glibc/wiki/PortStatus> for some time.  This
    patch makes no-FPU ColdFire use the soft-fp files; sfp-machine.h is
    made to include the nios2 version of sfp-machine.h which seems
    sufficiently generic for 32-bit systems.

        [BZ #13304]
        * sysdeps/m68k/coldfire/nofpu/s_fma.c: New file.
        * sysdeps/m68k/coldfire/nofpu/s_fmaf.c: Likewise.
        * sysdeps/m68k/coldfire/nofpu/sfp-machine.h: Likewise.
