In all GLSL ES versions output variables in fragment shader are allowed to be invariant.
From Section 4.6.1 ("The Invariant Qualifier") GLSL ES 1.00 spec: "Only the following variables may be declared as invariant: ... - Built-in special variables output from the fragment shader." From Section 4.6.1 ("The Invariant Qualifier") GLSL ES 3.00 spec: "Only variables output from a shader can be candidates for invariance." v2: moved new tests to tests/spec/glsl-es folders Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=107842 Signed-off-by: Danylo Piliaiev <danylo.pilia...@globallogic.com> --- tests/spec/glsl-es-1.00/compiler/invariant.frag | 17 +++++++++++++++++ tests/spec/glsl-es-3.00/compiler/invariant.frag | 15 +++++++++++++++ 2 files changed, 32 insertions(+) create mode 100644 tests/spec/glsl-es-1.00/compiler/invariant.frag create mode 100644 tests/spec/glsl-es-3.00/compiler/invariant.frag diff --git a/tests/spec/glsl-es-1.00/compiler/invariant.frag b/tests/spec/glsl-es-1.00/compiler/invariant.frag new file mode 100644 index 000000000..440d3dfb5 --- /dev/null +++ b/tests/spec/glsl-es-1.00/compiler/invariant.frag @@ -0,0 +1,17 @@ +// [config] +// expect_result: pass +// glsl_version: 1.00 +// [end config] + +/* From Section 4.6.1 ("The Invariant Qualifier") GLSL ES 1.00 spec: + * + * "Only the following variables may be declared as invariant: + * Built-in special variables output from the fragment shader." + */ + +#version 100 + +invariant gl_FragColor; +invariant gl_FragData; + +void main() { } diff --git a/tests/spec/glsl-es-3.00/compiler/invariant.frag b/tests/spec/glsl-es-3.00/compiler/invariant.frag new file mode 100644 index 000000000..0b5002f9d --- /dev/null +++ b/tests/spec/glsl-es-3.00/compiler/invariant.frag @@ -0,0 +1,15 @@ +// [config] +// expect_result: pass +// glsl_version: 3.00 +// [end config] + +/* From Section 4.6.1 ("The Invariant Qualifier") GLSL ES 3.00 spec: + * + * "Only variables output from a shader can be candidates for invariance." + */ + +#version 300 es + +invariant out highp vec4 test; + +void main() { } -- 2.20.1 _______________________________________________ Piglit mailing list Piglit@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/piglit
