Added files: (Branch: backend-hacking-branch)
ghc/compiler/codeGen CgPrimOp.hs
Log:
- Add CgPrimOp
- split off the not-definitely-inline MachOps into a separate type,
CallishMachOp. Change the CmmCall constructor to take a CmmCallTarget,
which is either a foreign call as before, or a CallishMachOp.
- Attach (Maybe [GlobalReg]) to a CmmCall, to indicate which of the
GlobalRegs need to be saved across the call (only applies to
VanillaReg, FloatReg, DoubleReg and LongReg - the others should be
automatically saved by the backend).
- define cmmOffsetExpr and cmmIndexExpr in CmmUtils, and define
CgUtils.cmmOffsetExprW in terms of CmmUtils.cmmOffsetExpr.
- MachOp now exports machRepLogWidth, to get at the log_2 of the width
(in bytes) of a MachRep. Useful for shifting by the size of a MachRep.
