From 74963469a169b49d61196e3a3b33a903ea8bfede Mon Sep 17 00:00:00 2001 From: Tim Foley Date: Wed, 12 Jul 2017 11:07:45 -0700 Subject: Add basic reflection query for checking if entry point is "sample-rate" - This really just checks two basic things: 1. Was there any global variable declared with `in` and `sample`? 2. Did any code encountered during lowering referenece `gl_SampleIndex`? - This doesn't cover what HLSL could need, nor what we would need for cross-compilation. Consider it GLSL-specific for now. - In order to generate the information with even a reasonable chance of being accurate (not giving a ton of false positives) I tried to integrate the checks into the lowering process (so they only see code that is referenced, one hopes). - For this to work with my testing setup, I needed to make sure that lowering is always performed, prior to emitting reflection info - This change broke several reflection tests, because they had been using code that wouldn't actually pass the downstream compiler. I checked in fixes for those. --- tests/reflection/sample-rate-input.glsl | 15 +++++++++++++++ 1 file changed, 15 insertions(+) create mode 100644 tests/reflection/sample-rate-input.glsl (limited to 'tests/reflection/sample-rate-input.glsl') diff --git a/tests/reflection/sample-rate-input.glsl b/tests/reflection/sample-rate-input.glsl new file mode 100644 index 000000000..66763f45d --- /dev/null +++ b/tests/reflection/sample-rate-input.glsl @@ -0,0 +1,15 @@ +//TEST(smoke):SIMPLE:-profile ps_4_0 -no-checking -target reflection-json + +// Check that we report sample-rate entry point input correctly + +uniform texture2D t; +uniform sampler s; + +sample in vec2 uv; + +out vec4 c; + +void main() +{ + c = texture(sampler2D(t,s), uv); +} -- cgit v1.2.3
