emitRtsCall Source

Arguments

:: PackageId	package the function is in
-> FastString	name of function
-> [CmmHinted CmmExpr]	function args
-> Bool	whether this is a safe call
-> Code	cmm code

Emit code to call a Cmm function.

emitRtsCallWithVols :: PackageId -> FastString -> [CmmHinted CmmExpr] -> [GlobalReg] -> Bool -> Code Source

emitRtsCallWithResult :: LocalReg -> ForeignHint -> PackageId -> FastString -> [CmmHinted CmmExpr] -> Bool -> Code Source

assignTemp :: CmmExpr -> FCode CmmExpr Source

If the expression is trivial, return it. Otherwise, assign the expression to a temporary register and return an expression referring to this register.

assignTemp_ :: CmmExpr -> FCode CmmExpr Source

If the expression is trivial and doesn't refer to a global register, return it. Otherwise, assign the expression to a temporary register and return an expression referring to this register.

tagToClosure :: TyCon -> CmmExpr -> CmmExpr Source

callerSaves :: GlobalReg -> Bool Source

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

callerSaveVolatileRegs :: Maybe [GlobalReg] -> ([CmmStmt], [CmmStmt])Source

get_GlobalReg_addr :: 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.

activeStgRegs :: [GlobalReg]Source

Here is where the STG register map is defined for each target arch. The order matters (for the llvm backend anyway)! We must make sure to maintain the order here with the order used in the LLVM calling conventions. Note that also, this isn't all registers, just the ones that are currently possbily mapped to real registers.

fixStgRegisters :: RawCmmTop -> RawCmmTop Source

Fixup global registers so that they assign to locations within the RegTable if they aren't pinned for the current target.
