Erik Faye-Lund 1905b38207 shader: correct swizzles from TGSI_SEMANTIC_SAMPLEPOS ... TGSI defines TGSI_SEMANTIC_SAMPLEPOS as a 4-component vector with Z and W set to 0. However, if we ever try to reach thez and w compoents, we run into trouble because this is implemented as a swizzle on gl_SamplePosition instead. And gl_SamplePosition only has x and y. It seems that recent versions of mesa does just this, causing shader-compilation errors during dEQP tests. This fixes regressions in the following tests: dEQP-GLES31.functional.shaders.sample_variables.sample_pos.correctness.singlesample_texture dEQP-GLES31.functional.shaders.sample_variables.sample_pos.correctness.multisample_texture_1 dEQP-GLES31.functional.shaders.sample_variables.sample_pos.correctness.multisample_texture_2 dEQP-GLES31.functional.shaders.sample_variables.sample_pos.correctness.multisample_texture_4 dEQP-GLES31.functional.shaders.sample_variables.sample_pos.correctness.multisample_texture_8 dEQP-GLES31.functional.shaders.sample_variables.sample_pos.correctness.singlesample_rbo dEQP-GLES31.functional.shaders.sample_variables.sample_pos.correctness.multisample_rbo_1 dEQP-GLES31.functional.shaders.sample_variables.sample_pos.correctness.multisample_rbo_2 dEQP-GLES31.functional.shaders.sample_variables.sample_pos.correctness.multisample_rbo_4 dEQP-GLES31.functional.shaders.sample_variables.sample_pos.correctness.multisample_rbo_8 dEQP-GLES31.functional.shaders.sample_variables.sample_pos.distribution.multisample_texture_1 dEQP-GLES31.functional.shaders.sample_variables.sample_pos.distribution.multisample_texture_2 dEQP-GLES31.functional.shaders.sample_variables.sample_pos.distribution.multisample_texture_4 dEQP-GLES31.functional.shaders.sample_variables.sample_pos.distribution.multisample_texture_8 dEQP-GLES31.functional.shaders.multisample_interpolation.interpolate_at_offset.at_sample_position.default_framebuffer Signed-off-by: Erik Faye-Lund <erik.faye-lund@collabora.com> Reviewed-by: Jakob Bornecrantz <jakob@collabora.com> Reviewed-by: Gurchetan Singh <gurchetansingh@chromium.org> Signed-off-by: Dave Airlie <airlied@redhat.com>		6 years ago
