Note that there are important steps to take when updating ANGLE. See https://trac.webkit.org/wiki/UpdatingANGLE
Comment on attachment 436546 [details] Patch Great work Kimmo diagnosing and fixing this. It sounds like you've carefully analyzed what was going wrong here, so looks good to me. It would be good if Kyle could look at this too before landing. (As an aside, I wish we'd finished the upstreaming process so that large changes like this didn't make WebKit's and ANGLE's code diverge further.) r+
Discussing with Kyle, he thinks this is ok. To the best of my knowledge, all the expected conformance tests still pass.
