The Cretonne meta language is used to describe Cretonne instructions, both the target independent ones in the base instruction set and real target instructions. Start by providing type definitions matching langref, and begin the meta language reference using autodoc to pull in the PYthon definitions.

The Cretonne meta language is used to define instructions for Cretonne. It is a
|
|
domain specific language embedded in Python.
|
|
|
|
An instruction set is described by a Python module under the :file:`meta`
|
|
directory that has a global variable called ``instructions``. The basic
|
|
Cretonne instruction set described in :doc:`langref` is defined by the Python
|
|
module :mod:`cretonne.instrs`.
|
|
|
|
Types
|
|
=====
|
|
|
|
Concrete value types are represented as instances of :class:`cretonne.Type`. There are
|
|
subclasses to represent scalar and vector types.
