Description Mark Janes 2014-10-02 23:48:13 UTC

a9f8296dbb4ee9fba22c4c2af625eaa29676f002 causes piglit failures on the following tests:

 glslparsertest.glsl2.gst-gl-glass.frag
 glslparsertest.glsl2.norsetto-bumptbn_sh_fp.frag

Since this won't be fixed immediately, the tests are marked as expected failures in the intel jenkins regression tool.

Comment 1 Matt Turner 2015-01-12 23:46:34 UTC

I sent a patch that fixes this:

> i965/fs: Don't use backend_visitor::exec_list after creating the CFG.
