Documentation
fixStgRegisters :: Platform -> RawCmmDecl -> RawCmmDecl Source #
Fixup global registers so that they assign to locations within the RegTable if they aren't pinned for the current target.
baseRegOffset :: Platform -> GlobalReg -> Int Source #
get_Regtable_addr_from_offset :: Platform -> Int -> CmmExpr Source #
regTableOffset :: Platform -> Int -> CmmExpr Source #
get_GlobalReg_addr :: Platform -> 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.
