Documentation
type LlvmCmmTop = GenCmmTop LlvmData [CmmStatic] (ListGraph LlvmStatement)
type LlvmUnresData = (CLabel, Section, LlvmType, [UnresStatic])
Unresolved code. Of the form: (data label, data type, unresolved data)
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)
Get initial Llvm 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.
llvmFunSig :: CLabel -> LlvmLinkageType -> LlvmFunctionDecl
Llvm Function signature
llvmStdFunAttrs :: [LlvmFuncAttr]
Llvm standard fun attributes
Alignment to use for functions
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
.
