LLVM.Target

A Target describes that for which code may be intended. Targets are used both during actual | lowering of LLVM IR to machine code and by some optimization passes which use the target to | judge costs.

lookupTarget

Arguments

:: Maybe String

arch

-> String

"triple" - e.g. x86_64-unknown-linux-gnu

-> ExceptT String IO (Target, String)

Find a Target given an architecture and/or a "triple". | http://llvm.org/doxygen/structllvm_1_1TargetRegistry.html#a3105b45e546c9cc3cf78d0f2ec18ad89 | Be sure to run either initializeAllTargets or initializeNativeTarget before expecting this to succeed, depending on what target(s) you want to use.

readPrec :: ReadPrec CPUFeature

readListPrec :: ReadPrec [CPUFeature]

Show CPUFeature

Methods

showsPrec :: Int -> CPUFeature -> ShowS

show :: CPUFeature -> String

showList :: [CPUFeature] -> ShowS

(Monad d, DecodeM d String es) => DecodeM d (Map CPUFeature Bool) es

Methods

decodeM :: es -> d (Map CPUFeature Bool)

EncodeM e String es => EncodeM e (Map CPUFeature Bool) es

Methods

withTargetOptions :: (TargetOptions -> IO a) -> IO a

bracket creation and destruction of a TargetOptions object

peekTargetOptions :: TargetOptions -> IO Options

get all target options

pokeTargetOptions :: Options -> TargetOptions -> IO ()

set all target options

withTargetMachine

Arguments

:: Target

-> String

triple

-> String

cpu

-> Map CPUFeature Bool

features

-> TargetOptions

-> Model

-> Model

-> Level

-> (TargetMachine -> IO a)

-> IO a

bracket creation and destruction of a TargetMachine

withHostTargetMachine :: (TargetMachine -> IO a) -> ExceptT String IO a

Bracket creation and destruction of a TargetMachine configured for the host

getTargetLowering :: TargetMachine -> IO TargetLowering

get the TargetLowering of a TargetMachine

getTargetMachineTriple :: TargetMachine -> IO String

the target triple corresponding to the target machine

getDefaultTargetTriple :: IO String

the default target triple that LLVM has been configured to produce code for

getProcessTargetTriple :: IO String

a target triple suitable for loading code into the current process

getHostCPUName :: IO String

the LLVM name for the host CPU

getHostCPUFeatures :: IO (Map CPUFeature Bool)

a space-separated list of LLVM feature names supported by the host CPU

getTargetMachineDataLayout :: TargetMachine -> IO DataLayout

DataLayout to use for the given TargetMachine

initializeNativeTarget :: IO ()

Initialize the native target. This function is called automatically in these Haskell bindings when creating an ExecutionEngine which will require it, and so it should not be necessary to call it separately.

initializeAllTargets :: IO ()

Initialize all targets so they can be found by lookupTarget

data TargetLibraryInfo

getLibraryFunction :: TargetLibraryInfo -> String -> IO (Maybe LibraryFunction)

Look up a LibraryFunction by its standard name

getLibraryFunctionName :: TargetLibraryInfo -> LibraryFunction -> IO String

Get a the current name to be emitted for a LibraryFunction

setLibraryFunctionAvailableWithName

Arguments

:: TargetLibraryInfo

-> LibraryFunction

-> String

The function name to be emitted

-> IO ()

Set the name of the function on the target platform that corresponds to funcName

withTargetLibraryInfo

Arguments

:: String

triple

-> (TargetLibraryInfo -> IO a)

-> IO a

look up information about the library functions available on a given platform
