Initialization and finalization

.. currentmodule:: llvmlite.binding

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

  • .. function:: initialize()

   Initialize the LLVM core.


  • .. function:: initialize_all_targets()

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


  • .. function:: initialize_all_asmprinters()

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


  • .. function:: initialize_native_target()

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



  • .. function:: initialize_native_asmprinter()

   Initialize the native assembly printer.



  • .. function:: initialize_native_asmparser()

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


  • .. function:: shutdown()

   Shut down the LLVM core.



  • .. data:: 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.
