1395313955 code generator fuses the operations. Fusion is not guaranteed, even if
1395413956 the target platform supports it. If a fused multiply-add is required, the
13955 corresponding llvm.fma.\* intrinsic function should be used
13957 corresponding :ref:`llvm.fma ` intrinsic function should be used
1395613958 instead. This never sets errno, just as '``llvm.fma.*``'.
