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.
