Description Kai 2013-11-06 17:58:41 UTC
Running "spec/EXT_transform_feedback/order arrays triangles" from Piglit (and some other tests) with the stack specified below, I'm getting the following LLVM error:
> LLVM ERROR: Cannot select: 0x8bee90: i1 = truncate 0x8c06b0 [ORD=40] [ID=16]

This is still an issue with Mesa Git:master/21ae5135dd and LLVM SVN:trunk/r195051. But since there are some minor changes in the shader dump (besides the formatting changes), I'm attaching a new version of it.
