type LlvmCmmTop = GenCmmTop LlvmData [CmmStatic] (ListGraph LlvmStatement)

type LlvmBasicBlock = GenBasicBlock LlvmStatement

type LlvmUnresData = (CLabel, Section, LlvmType, [UnresStatic])

Unresolved code. Of the form: (data label, data type, unresolved data)

type LlvmData = ([LMGlobal], [LlvmType])

Top level LLVM Data (globals and type aliases)

type UnresLabel = CmmLit

An unresolved Label.

Labels are unresolved when we haven't yet determined if they are defined in the module we are currently compiling, or an external one.

type UnresStatic = Either UnresLabel LlvmStatic

type LlvmEnv = (LlvmEnvMap, LlvmEnvMap)

initLlvmEnv :: LlvmEnv

Get initial Llvm environment.

clearVars :: LlvmEnv -> LlvmEnv

Clear variables from the environment.

varLookup :: Uniquable key => key -> LlvmEnv -> Maybe LlvmType

varInsert :: Uniquable key => key -> LlvmType -> LlvmEnv -> LlvmEnv

funLookup :: Uniquable key => key -> LlvmEnv -> Maybe LlvmType

Lookup functions in the environment.

funInsert :: Uniquable key => key -> LlvmType -> LlvmEnv -> LlvmEnv

Insert functions into the environment.

cmmToLlvmType :: CmmType -> LlvmType

Translate a basic CmmType to an LlvmType.

widthToLlvmFloat :: Width -> LlvmType

Translate a Cmm Float Width to a LlvmType.

widthToLlvmInt :: Width -> LlvmType

Translate a Cmm Bit Width to a LlvmType.

llvmFunTy :: LlvmType

Llvm Function type for Cmm function

llvmFunSig :: CLabel -> LlvmLinkageType -> LlvmFunctionDecl

Llvm Function signature

llvmStdFunAttrs :: [LlvmFuncAttr]

Llvm standard fun attributes

llvmFunAlign :: LMAlign

Alignment to use for functions

llvmInfAlign :: LMAlign

Alignment to use for into tables

llvmPtrBits :: Int

Pointer width

mkLlvmFunc :: CLabel -> LlvmLinkageType -> LMSection -> LlvmBlocks -> LlvmFunction

Create a Haskell function in LLVM.

tysToParams :: [LlvmType] -> [LlvmParameter]

Convert a list of types to a list of function parameters (each with no parameter attributes)

strCLabel_llvm :: CLabel -> LMString

Pretty print a `CLabel`.

genCmmLabelRef :: CLabel -> LMGlobal

Create an external definition for a `CLabel` defined in another module.

genStringLabelRef :: LMString -> LMGlobal

As above (`genCmmLabelRef`) but taking a `LMString`, not `CLabel`.
