def FMSUB_H : FPFMAH_rrr_frm<OPC_MSUB, "fmsub.h">,
- Sched<[]>;
+ Sched<[WriteFMulSub16, ReadFMulSub16, ReadFMulSub16, ReadFMulSub16]>;
def : FPFMAHDynFrmAlias<FMSUB_H, "fmsub.h">;
----------------
Does anyone know why we have different classes for FMADD and FMSUB? It doesn't seem like they are likely to be different.
