From: Emil Velikov <[email protected]> As per the spec hunk: "The specified offset must be a multiple of the base alignment of the type of the block member it qualifies, or a compile-time error results."
v2: - Fix typo - enhanced-layout > enhanced-layouts - Prefix uniform tests with ubo - Add ssbo equivalent tests - Quote the correct spec hunk in commit msg Signed-off-by: Emil Velikov <[email protected]> --- .../ssbo-offset-multiple-of-base-member-align.vert | 27 ++++++++++++++++++++++ .../ubo-offset-multiple-of-base-member-align.vert | 26 +++++++++++++++++++++ 2 files changed, 53 insertions(+) create mode 100644 tests/spec/arb_enhanced_layouts/compiler/explicit-offsets/ssbo-offset-multiple-of-base-member-align.vert create mode 100644 tests/spec/arb_enhanced_layouts/compiler/explicit-offsets/ubo-offset-multiple-of-base-member-align.vert diff --git a/tests/spec/arb_enhanced_layouts/compiler/explicit-offsets/ssbo-offset-multiple-of-base-member-align.vert b/tests/spec/arb_enhanced_layouts/compiler/explicit-offsets/ssbo-offset-multiple-of-base-member-align.vert new file mode 100644 index 0000000..283f7b7 --- /dev/null +++ b/tests/spec/arb_enhanced_layouts/compiler/explicit-offsets/ssbo-offset-multiple-of-base-member-align.vert @@ -0,0 +1,27 @@ +// [config] +// expect_result: fail +// glsl_version: 4.30 +// require_extensions: GL_ARB_enhanced_layouts GL_ARB_shader_storage_buffer_object +// check_link: false +// [end config] +// +// ARB_enhanced_layouts spec says: +// "The specified offset must be a +// multiple of the base alignment of the type of the block member it +// qualifies, or a compile-time error results." +// +// Tests for successful compilation, when the block is of std140 layout. +// + +#version 430 +#extension GL_ARB_enhanced_layouts : enable +#extension GL_ARB_shader_storage_buffer_object : enable + +layout(std430) buffer b { + layout(offset = 0) float f1; + layout(offset = 2) float f2; // Wrong: offset must be aligned to multiple of sizeof(float) +}; + +void main() +{ +} diff --git a/tests/spec/arb_enhanced_layouts/compiler/explicit-offsets/ubo-offset-multiple-of-base-member-align.vert b/tests/spec/arb_enhanced_layouts/compiler/explicit-offsets/ubo-offset-multiple-of-base-member-align.vert new file mode 100644 index 0000000..b3ce2e2 --- /dev/null +++ b/tests/spec/arb_enhanced_layouts/compiler/explicit-offsets/ubo-offset-multiple-of-base-member-align.vert @@ -0,0 +1,26 @@ +// [config] +// expect_result: fail +// glsl_version: 1.40 +// require_extensions: GL_ARB_enhanced_layouts +// check_link: false +// [end config] +// +// ARB_enhanced_layouts spec says: +// "The specified offset must be a +// multiple of the base alignment of the type of the block member it +// qualifies, or a compile-time error results." +// +// Tests for successful compilation, when the block is of std140 layout. +// + +#version 140 +#extension GL_ARB_enhanced_layouts : enable + +layout(std140) uniform block { + layout(offset = 0) float f1; + layout(offset = 2) float f2; // Wrong: offset must be aligned to multiple of sizeof(float) +}; + +void main() +{ +} -- 2.6.1 _______________________________________________ Piglit mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/piglit
