Documentation
type LlvmCmmDecl = GenCmmDecl [LlvmData] (Maybe CmmStatics) (ListGraph LlvmStatement) Source #
type LiveGlobalRegs = [GlobalReg] Source #
Global registers live on proc entry
type LlvmUnresData = (CLabel, Section, LlvmType, [UnresStatic]) Source #
Unresolved code. Of the form: (data label, data type, unresolved data)
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, Int) Source #
LLVM Version Number
supportedLlvmVersion :: LlvmVersion Source #
The LLVM Version that is currently supported.
llvmVersionStr :: LlvmVersion -> String Source #
The Llvm monad. Wraps LlvmEnv state as well as the IO monad
Instances
runLlvm :: DynFlags -> LlvmVersion -> BufHandle -> UniqSupply -> LlvmM () -> IO () Source #
Get initial Llvm environment.
withClearVars :: LlvmM a -> LlvmM a Source #
Clear variables from the environment for a subcomputation
varLookup :: Uniquable key => key -> LlvmM (Maybe LlvmType) Source #
Lookup variables or functions in the environment.
varInsert :: Uniquable key => key -> LlvmType -> LlvmM () Source #
Insert variables or functions into the environment.
markStackReg :: GlobalReg -> LlvmM () Source #
Set a register as allocated on the stack
funLookup :: Uniquable key => key -> LlvmM (Maybe LlvmType) Source #
Lookup variables or functions in the environment.
funInsert :: Uniquable key => key -> LlvmType -> LlvmM () Source #
Insert variables or functions into the environment.
getLlvmVer :: LlvmM LlvmVersion Source #
Get the LLVM version we are generating code for
getDynFlags :: HasDynFlags m => m DynFlags Source #
getDynFlag :: (DynFlags -> a) -> LlvmM a Source #
Get the platform we are generating code for
getLlvmPlatform :: LlvmM Platform Source #
Get the platform we are generating code for
dumpIfSetLlvm :: DumpFlag -> String -> SDoc -> LlvmM () Source #
Dumps the document if the corresponding flag has been set by the user
renderLlvm :: SDoc -> LlvmM () Source #
Prints the given contents to the output handle
markUsedVar :: LlvmVar -> LlvmM () Source #
Marks a variable as "used"
getUsedVars :: LlvmM [LlvmVar] Source #
Return all variables marked as "used" so far
ghcInternalFunctions :: LlvmM () Source #
Here we pre-initialise some functions that are used internally by GHC
so as to make sure they have the most general type in the case that
user code also uses these functions but with a different type than GHC
internally. (Main offender is treating return type as void instead of
'void *'). Fixes trac #5486.
getMetaUniqueId :: LlvmM MetaId Source #
Allocate a new global unnamed metadata identifier
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.
llvmFunSig :: LiveGlobalRegs -> CLabel -> LlvmLinkageType -> LlvmM LlvmFunctionDecl Source #
Llvm Function signature
llvmFunArgs :: DynFlags -> LiveGlobalRegs -> [LlvmVar] Source #
A Function's arguments
llvmStdFunAttrs :: [LlvmFuncAttr] Source #
Llvm standard fun attributes
llvmFunAlign :: DynFlags -> LMAlign Source #
Alignment to use for functions
llvmInfAlign :: DynFlags -> LMAlign Source #
Alignment to use for into tables
llvmPtrBits :: DynFlags -> Int Source #
Pointer width
tysToParams :: [LlvmType] -> [LlvmParameter] Source #
Convert a list of types to a list of function parameters (each with no parameter attributes)
getGlobalPtr :: LMString -> LlvmM LlvmVar Source #
Create/get a pointer to a global value. Might return an alias if the value in question hasn't been defined yet. We especially make no guarantees on the type of the returned pointer.
