Example

A trivial function

Define a function adding two double-precision floating-point numbers.

.. literalinclude:: /../../examples/ir_fpadd.py

The generated LLVM :term:`IR` is printed out at the end, and should look like this:

; ModuleID = "examples/ir_fpadd.py"
target triple = "unknown-unknown-unknown"
target datalayout = ""

define double @"fpadd"(double %".1", double %".2")
{
entry:
  %"res" = fadd double %".1", %".2"
  ret double %"res"
}

To learn how to compile and execute this function, refer to the :ref:`binding layer <binding-layer>` documentation.
