type LlvmCmmTop = GenCmmTop [LlvmData] (Maybe CmmStatics) (ListGraph LlvmStatement)Source

type LlvmBasicBlock = GenBasicBlock LlvmStatement Source

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

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

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

Top level LLVM Data (globals and type aliases)

type UnresLabel = CmmLit Source

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 Source

type LlvmVersion = Int Source

LLVM Version Number

defaultLlvmVersion :: LlvmVersion Source

The LLVM Version we assume if we don't know

data LlvmEnv Source

initLlvmEnv :: LlvmEnv Source

Get initial Llvm environment.

clearVars :: LlvmEnv -> LlvmEnv Source

Clear variables from the environment.

varLookup, funLookup :: Uniquable key => key -> LlvmEnv -> Maybe LlvmType Source

Lookup functions in the environment.

varInsert, funInsert :: Uniquable key => key -> LlvmType -> LlvmEnv -> LlvmEnv Source

Insert functions into the environment.

getLlvmVer :: LlvmEnv -> LlvmVersion Source

Get the LLVM version we are generating code for

setLlvmVer :: LlvmVersion -> LlvmEnv -> LlvmEnv Source

Set the LLVM version we are generating code for

cmmToLlvmType :: CmmType -> LlvmType Source

Translate a basic CmmType to an LlvmType.

widthToLlvmFloat :: Width -> LlvmType Source

Translate a Cmm Float Width to a LlvmType.

widthToLlvmInt :: Width -> LlvmType Source

Translate a Cmm Bit Width to a LlvmType.

llvmFunTy :: LlvmType Source

Llvm Function type for Cmm function

llvmFunSig :: CLabel -> LlvmLinkageType -> LlvmFunctionDecl Source

Llvm Function signature

llvmStdFunAttrs :: [LlvmFuncAttr]Source

Llvm standard fun attributes

llvmFunAlign :: LMAlign Source

Alignment to use for functions

llvmInfAlign :: LMAlign Source

Alignment to use for into tables

llvmPtrBits :: Int Source

Pointer width

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

Create a Haskell function in LLVM.

tysToParams :: [LlvmType] -> [LlvmParameter]Source

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

strCLabel_llvm :: CLabel -> LMString Source

Pretty print a CLabel.

genCmmLabelRef :: CLabel -> LMGlobal Source

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

genStringLabelRef :: LMString -> LMGlobal Source

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