Documentation
type LlvmCmmTop = GenCmmTop LlvmData [CmmStatic] (ListGraph LlvmStatement)Source
type LlvmUnresData = (CLabel, Section, LlvmType, [UnresStatic])Source
Unresolved code. Of the form: (data label, data type, unresolved data)
type UnresLabel = CmmLitSource
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.
Get initial Llvm environment.
funLookup :: Uniquable key => key -> LlvmEnv -> Maybe LlvmTypeSource
Lookup functions in the environment.
funInsert :: Uniquable key => key -> LlvmType -> LlvmEnv -> LlvmEnvSource
Insert functions into the environment.
cmmToLlvmType :: CmmType -> LlvmTypeSource
Translate a basic CmmType to an LlvmType.
widthToLlvmFloat :: Width -> LlvmTypeSource
Translate a Cmm Float Width to a LlvmType.
widthToLlvmInt :: Width -> LlvmTypeSource
Translate a Cmm Bit Width to a LlvmType.
llvmFunSig :: CLabel -> LlvmLinkageType -> LlvmFunctionDeclSource
Llvm Function signature
llvmStdFunAttrs :: [LlvmFuncAttr]Source
Llvm standard fun attributes
Alignment to use for functions
Alignment to use for into tables
Pointer width
mkLlvmFunc :: CLabel -> LlvmLinkageType -> LMSection -> LlvmBlocks -> LlvmFunctionSource
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 -> LMStringSource
Pretty print a CLabel.
genCmmLabelRef :: CLabel -> LMGlobalSource
Create an external definition for a CLabel defined in another module.
genStringLabelRef :: LMString -> LMGlobalSource
As above (genCmmLabelRef) but taking a LMString, not CLabel.
