#initialize(mod, options = {}) ⇒ ExecutionEngine

TODO:

Add :mcjmm option (MCJIT memory manager)

Note:

You should call ‘LLVM.init_jit(true)` before creating an execution engine.

Create a MCJIT execution engine.

Parameters:

  • mod (LLVM::Module) —

    module

  • options (Hash{Symbol => Object}) (defaults to: {}) —

    options

Options Hash (options):

  • :opt_level (Integer) — default: 2 —

    Optimization level

  • :code_model (Integer) — default: 0 —

    Code model types

  • :no_frame_pointer_elim (Boolean) — default: false —

    Disable frame pointer elimination optimization

  • :enable_fast_i_sel (Boolean) — default: false —

    Enables fast-path instruction selection
