Subject: swrast: fix active attribs with atifragshader
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=17f1c49b9ad05af4f6482f6fa950e5dcc1a779d1;p=mesa.git

swrast: fix active attribs with atifragshader

Only include the ones that can be used by the shader.

This fixes texture coordinates, which were completely wrong,
because WPOS was included in the list of attribs. It also
increases performance noticeably.
