LLVM.Module

Description

A Module holds a C++ LLVM IR module. Modules may be converted to or from strings or Haskell ASTs, or added to an ExecutionEngine and so JIT compiled to get function pointers.

Synopsis

Documentation

newtype File Source #

A newtype to distinguish strings used for paths from other strings

Constructors

File FilePath 

withModuleFromAST :: Context -> Module -> (Module -> IO a) -> ExceptT String IO a Source #

This function will call disposeModule after the callback exits. Calling deleteModule prevents double free errors. As long as you only call functions provided by llvm-hs this should not be necessary since llvm-hs takes care of this.

moduleAST :: Module -> IO Module Source #

Get an LLVM.AST.Module from a LLVM.Module - i.e. raise C++ objects into an Haskell AST.

withModuleFromLLVMAssembly :: LLVMAssemblyInput s => Context -> s -> (Module -> IO a) -> ExceptT String IO a Source #

parse Module from LLVM assembly

moduleLLVMAssembly :: Module -> IO String Source #

generate LLVM assembly from a Module

writeLLVMAssemblyToFile :: File -> Module -> ExceptT String IO () Source #

write LLVM assembly for a Module to a file

withModuleFromBitcode :: BitcodeInput b => Context -> b -> (Module -> IO a) -> ExceptT String IO a Source #

parse Module from LLVM bitcode

moduleBitcode :: Module -> IO ByteString Source #

generate LLVM bitcode from a Module

writeBitcodeToFile :: File -> Module -> ExceptT String IO () Source #

write LLVM bitcode from a Module into a file

moduleTargetAssembly :: TargetMachine -> Module -> ExceptT String IO String Source #

produce target-specific assembly as a String

writeTargetAssemblyToFile :: TargetMachine -> File -> Module -> ExceptT String IO () Source #

write target-specific assembly directly into a file

moduleObject :: TargetMachine -> Module -> ExceptT String IO ByteString Source #

produce target-specific object code as a ByteString

writeObjectToFile :: TargetMachine -> File -> Module -> ExceptT String IO () Source #

write target-specific object code directly into a file

linkModules Source #

Arguments

:: Module

The module into which to link

-> Module

The module to link into the other (this module is destroyed)

-> ExceptT String IO () 

link LLVM modules - move or copy parts of a source module into a destination module. Note that this operation is not commutative - not only concretely (e.g. the destination module is modified, becoming the result) but abstractly (e.g. unused private globals in the source module do not appear in the result, but similar globals in the destination remain). The source module is destroyed.
