[Mesa-dev] [PATCH v3 00/24] auto-generate pack/unpack functions

[Iago Toral Quiroga]

This is the first of two series that aim to address:
https://bugs.freedesktop.org/show_bug.cgi?id=84566

A branch with this series is available here:
https://github.com/Igalia/mesa/tree/itoral-autogen-packing-review-v3

v1: http://lists.freedesktop.org/archives/mesa-dev/2014-November/070898.html

Main changes in v3:
  - Do not use a union/struct and bitmasks to implement and access
    mesa_array_format, that won't work on big-endian as pointed out by Ian.
    The new implementation drops the union/struct and accesses
    mesa_array_format as a uint32_t bitfield only.
  - Remove the unused float_to_uint helper (last patch in the series)

Notes:
  - Patches 1, 3-7, 9 are already reviewed-by Ian.

Tested on i965, classic swrast and gallium (radeon, nouveau, llvmpipe) without
regressions.
