The MIPS DSP ASE performance patches are always welcome. Just the
timing is a bit bad this time. Could you please update your patchset
and make it compatible with
http://lists.freedesktop.org/archives/pixman/2012-June/002085.html ?
So that the assembly code respects the interpolation precision
settings defined as BILINEAR_INTERPOLATION_BITS constant and "make
check" tests pass when setting it to 7 and 8. Thanks.
