These failures:
general/linestipple 
glean/paths 
spec/OpenGL_1.2_texwrap-3D-bordercolor 
spec/OpenGL_1.2_texwrap-3D-proj-bordercolor 
texturing/texrect-many 

bisect to commit 85a52bf, so they are likely a duplicate of 45872.  I'll update that bug report accordingly.

I haven't been able to reproduce the failure in bugs/point-sprite.

I'm still investigating the other failures.

Comment 2 Paul Berry 2012-02-10 15:26:05 UTC

The failure in spec/glsl-1.20/execution/clipping_vs-clip-vertex-const-reject is not a regression.  gl_ClipVertex has never worked for i915; however spec/glsl-1.20/execution/clipping_vs-clip-vertex-const-reject happened to pass by a complete coincidence, and commit 7d68c63 (which laid the necessary groundwork for gl_ClipVertex to be fully supported) eliminated the coincidence.

To make spec/glsl-1.20/execution/clipping_vs-clip-vertex-const-reject pass again, we would need to implement gl_ClipVertex support for i915.  See bug 45913, which provides additional information about what would be necessary to achieve this.

Comment 3 Paul Berry 2012-02-10 20:08:08 UTC

The failure in general/two-sided-lighting-separate-specular is unrelated to the other failures, so I've moved it to its own bug: bug 45917.

Comment 4 Paul Berry 2012-02-16 13:57:56 UTC

The failure in fbo/fbo-cubemap is unrelated to the other failures, so I've moved it to its own bug: bug 46196.
