             Bug #: 15503
           Summary: Support ARM VFPv4 VFMA instruction in fma
           Product: glibc
           Version: 2.17
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ports
        AssignedTo: unassigned@sourceware.org
        ReportedBy: jsm28@gcc.gnu.org
                CC: carlos@redhat.com, roland@gnu.org
    Classification: Unclassified


On ARM, VFPv4 has a fused multiply-add instruction VFMA.  This should be used
for the fmaf and fma functions in glibc, unconditionally if glibc is built for
VPFv4 (__ARM_FEATURE_FMA predefined by GCC), or through IFUNC (testing
HWCAP_ARM_VFPv4) otherwise.
