[Mesa-dev] [PATCH 0/3] Array object cleanup.

[Mathias Fröhlich]

Hi,

Following a short series of cleanup following the gl_array_object change.
The most important change is the use ot an ffs based loop to compute 
gl_array_object::_MaxElement. This change provides a noticable performance 
improovement for my average workloads.
To implement this, a small set of helper functions is introduced in the patch 
before, to compute the bitmasks of enabled arrays taking into account the 
aliasing rules for the different arrays.
The first patch just makes use of the recently introduced BITFIELD64_RANGE 
macro where it makes sense.

The complete changeset survives a piglit quick run for r600g/rv770 and swrast 
without regressions.

Please review.
Thanks

Mathias
