Allow attributes and uniforms to have the same name It is valid for an attribute and a uniform to have the same name as long as they are declared in different stages. Prior to this patch, if any shader stage declares a uniform we disallowed reusing that name for an attribute. From GLSL ES Spec 3.00.6, section 4.3.5: If a uniform variable name is declared in one stage (e.g., a vertex shader) but not in another (e.g., a fragment shader), then that name is still available in the other stage for a different use. This change allows Egginc game to work with ANGLE Bug: angleproject:5497 Tests: angle_end2end_tests - *UniformVariableNameReuseAcrossStages* *GlobalNamesConflict* Change-Id: I8f5657d40a213600d6fb48f63e37e4cdbae120b2 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2608865 Reviewed-by: Jamie Madill <jmadill@chromium.org> Reviewed-by: Shahbaz Youssefi <syoussefi@chromium.org> Commit-Queue: Mohan Maiya <m.maiya@samsung.com>
