[Mesa-dev] [RFC 00/13] Start using Khronos XML for generators

[Dylan Baker]

Currently we have two XML sources in mesa, the khronos xml, and the mesa xml.
The mesa xml is incredibly inaccurate (look at the number of commits to fix it),
has to be hand rolled for each extension, and has to be tracked individually by
build systems. The mesa xml is also problematic because it conflates the khronos
standard with mesa implementation information.

This series is the start of pulling the two apart and using the upstream khronos
xml and a separate mesa specific information, defined in a python file for easy
of access. This is not complete as of now, it's in RFC/just so you know what I'm
working on sort of form.

The goal is to replace all of the current generators with new generators based
off the khronos XML and mako.

There are two things I'm using here that will likely not be in the final
version, six and the attr module. They're just making initial bring up very
easy.

Dylan Baker (13):
  glapi/gen: gl_marshal_h.py: Use argparse instead of getopt
  glapi/gen: use main function in gl_marshal_h.py
  glapi/gen: Add some helpers that will be used generators
  gl.xml: update to git commit 58fcee1918e90cb817693c6df8c1f8d3e4f3e48e
  gen_mesa_data: script to convert mesa xml into mesa_data entries
  glapi/gen: Add a new mesa_data module
  mapi/glapi/gen: Add python module with abstractions from Khronos XML
  mapi/glapi/gen: Use new infastructure for gl_marshal_h.py
  begin generalizing gl_marshal_h.py for doing both.
  wip
  fixup! begin generalizing gl_marshal_h.py for doing both.
  fixup! wip
  wip: use new generator for marshal.c
