From: Mathias Fröhlich <mathias.froehl...@gmx.net>
Hi all,
following a series with performance improvements
for cpu/draw bound applications. This part makes
more use of the bitmask/ffs technique for iterating
a set of enabled items. The gains are not huge
but they are noticable for some of my favourite
workloads.
Changes in v2:
Past the suggestion from Brian Paul and the
discussion about maintainability I
switched to gallium/u_bit_scan{,64} style
functions for the series of changes.
Providing them and using them in some places
in core mesa make up the two new patches upfront.
Appart from that the problem spotted
by Roland Scheidegger is fixed and the changes
requested all around are incorporated.
Changes in v3:
Rename _mesa_bit_scan* to u_bit_scan*.
Comment formating changes.
Rebase to master.
Ok to push?
Thanks
Mathias
