Module: Mesa Branch: 7.11 Commit: 7722a54e60c9da080b557d6596e4c9d363ead515 URL: http://cgit.freedesktop.org/mesa/mesa/commit/?id=7722a54e60c9da080b557d6596e4c9d363ead515
Author: Ian Romanick <[email protected]> Date: Fri Dec 23 17:16:43 2011 -0800 glsl: Don't use base type for bit-not when there's an error Other parts of the compiler assume that expressions will have well-formed types or the error type. Just using the type of the thing being operated on can cause expressions like ~3.14 or ~false to not have a well-formed type. This could then result in an assertion failure in the context epxression handler. If there is an error processing the expression, set the type of the IR expression to error. Fixes piglit's bit-not-0[789].frag tests. NOTE: This is a candidate for the 7.11 branch.
