llvm-hs-5.1.0: General purpose LLVM bindings

Safe HaskellNone



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 Source #


:: Maybe ShortByteString


-> ShortByteString

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

-> IO (Target, ShortByteString) 

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. May throw LookupTargetException if no target is found.

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

bracket creation and destruction of a TargetOptions object

peekTargetOptions :: TargetOptions -> IO Options Source #

get all target options

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

set all target options

withTargetMachine Source #


:: Target 
-> ShortByteString


-> ByteString


-> Map CPUFeature Bool


-> TargetOptions 
-> Model 
-> Model 
-> Level 
-> (TargetMachine -> IO a) 
-> IO a 

bracket creation and destruction of a TargetMachine

withHostTargetMachine :: (TargetMachine -> IO a) -> IO a Source #

Bracket creation and destruction of a TargetMachine configured for the host

getTargetMachineTriple :: TargetMachine -> IO ShortByteString Source #

the target triple corresponding to the target machine

getDefaultTargetTriple :: IO ShortByteString Source #

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

getProcessTargetTriple :: IO ShortByteString Source #

a target triple suitable for loading code into the current process

getHostCPUName :: IO ByteString Source #

the LLVM name for the host CPU

getHostCPUFeatures :: IO (Map CPUFeature Bool) Source #

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

initializeNativeTarget :: IO () Source #

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 () Source #

Initialize all targets so they can be found by lookupTarget

setLibraryFunctionAvailableWithName Source #


:: TargetLibraryInfo 
-> LibraryFunction 
-> ShortByteString

The function name to be emitted

-> IO () 

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

withTargetLibraryInfo Source #


:: ShortByteString


-> (TargetLibraryInfo -> IO a) 
-> IO a 

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