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.

:: 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".

| Be sure to run either initializeAllTargets
or initializeNativeTarget
before expecting this to succeed, depending on what target(s) you want to use.
newtype CPUFeature Source
e.g. an instruction set extension
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
:: 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 Source
Bracket creation and destruction of a TargetMachine
configured for the host
getTargetLowering :: TargetMachine -> IO TargetLowering Source
get the TargetLowering
of a TargetMachine
getDefaultTargetTriple :: IO String Source
the default target triple that LLVM has been configured to produce code for
getProcessTargetTriple :: IO String Source
a target triple suitable for loading code into the current process
getHostCPUName :: IO String Source
the LLVM name for the host CPU
getHostCPUFeatures :: IO (Set CPUFeature) Source
a space-separated list of LLVM feature names supported by the host CPU
getTargetMachineDataLayout :: TargetMachine -> IO DataLayout Source
DataLayout
to use for the given TargetMachine
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
getLibraryFunction :: TargetLibraryInfo -> String -> IO (Maybe LibraryFunction) Source
Look up a LibraryFunction
by its standard name
getLibraryFunctionName :: TargetLibraryInfo -> LibraryFunction -> IO String Source
Get a the current name to be emitted for a LibraryFunction
setLibraryFunctionAvailableWithName Source
:: TargetLibraryInfo | |
-> LibraryFunction | |
-> String | The function name to be emitted |
-> IO () |
Set the name of the function on the target platform that corresponds to funcName
:: String | triple |
-> (TargetLibraryInfo -> IO a) | |
-> IO a |
look up information about the library functions available on a given platform
