Example---defining a simple function
====================================
.. _ir-fpadd:
This example defines a function that adds 2 double-precision,
floating-point numbers.
.. literalinclude:: ../examples/ir_fpadd.py
The generated LLVM
:ref:`intermediate representation <intermediate representation>`
is printed at the end:
.. code-block:: llvm
; 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"
}
