Note that there are important steps to take when updating ANGLE. See https://trac.webkit.org/wiki/UpdatingANGLE
Could you please provide a description in this bug of why this is being done, and how temporarily this is being removed?
Sure thing. We are seeing significant slow downs inside of the validateAST calls on debug builds leading to test timeouts. There are a significant number of transform passes as a part of the GLSL AST -> MSL translation, and currently each pass is validating the AST. Theses were mainly in place during development of the translator, and the correct fix is to move the validation to the very end after all of the transformations happen. To unblock further testing, we'd like to land this stopgap to run all of the debug testing, until we land the more correct fix (hopefully within the next few days.)
