llvm-general-3.2.6.0: General purpose LLVM bindings

Safe HaskellNone

LLVM.General.Target

Description

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.

Synopsis

Documentation

lookupTarget

Arguments

:: Maybe String

arch

-> String

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

-> ErrorT 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.

newtype CPUFeature

e.g. an instruction set extension

Constructors

CPUFeature String 

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

-> Set CPUFeature

features

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

bracket creation and destruction of a TargetMachine

withDefaultTargetMachine :: (TargetMachine -> IO a) -> ErrorT String IO a

Bracket creation and destruction of a TargetMachine configured for the host

getDefaultTargetTriple :: IO String

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

getHostCPUName :: IO String

the LLVM name for the host CPU

getHostCPUFeatures :: IO (Set CPUFeature)

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

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

withTargetLibraryInfo

Arguments

:: String

triple

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

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