Initialization and finalization

llvmlite.binding

You only need to call these functions once per process invocation.

• initialize()

  Initialize the LLVM core.

• initialize_all_targets()

  Initialize all targets. Must be called before targets can be looked up via the Target class.

• initialize_all_asmprinters()

  Initialize all code generators. Must be called before generating any assembly or machine code via the TargetMachine.emit_object and TargetMachine.emit_assembly methods.

• initialize_native_target()

  Initialize the native---host---target. Must be called once before doing any code generation.

• initialize_native_asmprinter()

  Initialize the native assembly printer.

• initialize_native_asmparser()

  Initialize the native assembly parser. Must be called for inline assembly to work.

• shutdown()

  Shut down the LLVM core.

• llvm_version_info

  A 3-integer tuple representing the LLVM version number.

  EXAMPLE: (3, 7, 1)

  Since LLVM is statically linked into the llvmlite DLL, this is guaranteed to represent the true LLVM version in use.
