emitDataLits :: CLabel -> [CmmLit] -> CodeSource
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 -> CodeSource
emitRtsCallWithResult :: LocalReg -> ForeignHint -> PackageId -> FastString -> [CmmHinted CmmExpr] -> Bool -> CodeSource
assignTemp :: CmmExpr -> FCode CmmExprSource
tagToClosure :: TyCon -> CmmExpr -> CmmExprSource
callerSaves :: GlobalReg -> BoolSource
Returns True if this global register is stored in a caller-saves
machine register.
get_GlobalReg_addr :: GlobalReg -> CmmExprSource
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 -> RawCmmTopSource
Fixup global registers so that they assign to locations within the RegTable if they aren't pinned for the current target.
