tagToClosure :: DynFlags -> TyCon -> CmmExpr -> CmmExpr Source #

mkTaggedObjectLoad :: DynFlags -> LocalReg -> LocalReg -> ByteOff -> DynTag -> CmmAGraph Source #

callerSaves :: Platform -> GlobalReg -> Bool Source #

Returns True if this global register is stored in a caller-saves machine register.

callerSaveVolatileRegs :: DynFlags -> (CmmAGraph, CmmAGraph) Source #

get_GlobalReg_addr :: DynFlags -> GlobalReg -> CmmExpr Source #

We map STG registers onto appropriate CmmExprs. Either they map to real machine registers or stored as offsets from BaseReg. Given a GlobalReg, get_GlobalReg_addr always produces the register table address for it.
