[Mesa-dev] [PATCH 00/45] Remove many of the FEATURE_* defines.

[Oliver McFadden]

Hi,

As requested here is the patch series which removes many of the FEATURE_*
defines, typically used to enable or disable some GL feature or extension.
I have ran this series through automatic git-bisect with a script to compile
Mesa.  The series is bisect-clean with the following configuration:

$ ./autogen.sh --prefix=/usr --without-gallium-drivers --with-dri-drivers=i965,swrast --enable-gles1 --enable-gles2

I expect it's also bisect-clean with all other configurations, but if you wish
for further testing with Gallium and more DRI drivers then I need to install and
setup some other packages.

mfeatures.h still exists and we still have FEATURE_GL, FEATURE_ES, FEATURE_ES1,
FEATURE_ES2, and FEATURE_remap_table.  I did not touch the last feature because
there is some Python code involved there and that's not my forte.

The features are removed in roughly the order they were specified in
mfeatures.h; I took some liberties where it would make things easier to do
out-of-order operations.

We probably have quite a few areas that are guarded by `#if FEATURE_GL' which
don't necessarily need to be due to the code checking the API; the goal of this
patch set was to reduce the feature defines down to GL, ES1 and ES2.  In that
regard it's successful.

A follow-up patch could look at removing redundant FEATURE_GL guards, but they
will not hurt anything.

Comments are welcome just hopefully not "rewrite the whole series" (although
that's usually how things turn out.)

Regards.
