1. spirv_execution_mode_id and spirv_decorate_id could support
specialization constants. The original implementation always
assume only normal frontend constants are valid. It is not true.
2. spirv_type donesn't support type_specifier as an option of
spirv_type_parameter. At present, only constant_expression is the
valid option.
Fix OpImageRead result type when compiling HLSL
- Per the Vulkan spec, OpImageRead must return a 4-component vector always. When compiling HLSL, loads from a RWTexture of a template type with < 4 components would incorrectly generate an OpImageRead with a < 4 component result, resulting in validation errors.
- This was previously fixed for OpImageFetch in commit 4425f24; this commit does the same thing for OpImageRead.
- Added associated tests and expanded existing image fetch tests to check all the different types of textures, in both float and int incarnations, for completeness.
- Update other HLSL tests involving OpImageRead
SPIR-V disallows bool in interface blocks, which is emulated with uint.
When loading a bool variable (through accessChainLoad()), it's converted
from uint to bool if it came from an interface block.
This was handled for bool and bvecN, but not for bool arrays. This
change implements the conversion for bool arrays.
Closes#2694
- Add support of SPIR-V execution mode qualifiers.
- Add support of SPIR-V storage class qualifier.
- Add support of SPIR-V decorate qualifiers.
- Add support of SPIR-V type specifier.
- Add support of SPIR-V intruction qualifiers.
- Add support of spirv_by_reference/spirv_literal parameter qualifier.
- Add shader stage macros introduced by this extension.
Previous check was missing type difference between uniform array
actual arg with stride decoration and the formal arg without. Now
does logical or component-wise copy where needed.
Fixes#2637
The glsl spec says:A shader will fail to compile if the value passed to the mem argument of an atomic memory function does not
correspond to a buffer or shared variable.
Replace uses of floating point log2 when we want an integer result from
an integer operand. This avoids concerns about accuracy of floating
point library functions.
Generate load of interpolant for first operand to GLSLstd450
InterpolateAt* SPIR-V ops. This allows the interpolants to
propagate from the input struct in the wrapper around main
into the shader during HLSL legalization. A new pass has been
added to legalization which will remove the load and replace
with the pointer of the load to create valid external
interpolate op.
Fixes#2584
gl_SecondaryPositionNV and gl_PositionPerViewNV are inconsistently
declared inside and outside of gl_PerVertex. This breaks interface block
matching. For now ignore these errors since it should be fixed with how
they are declared.
Avoid adding global uniform blocks to stages that don't already have it.
Otherwise multiple stages point to the same block object, and a
remapping that occurs later on will change the mapping on multiple
stages.
Issue #2483
According to GLSL spec the prototype is:
uint rayQueryGetIntersectionInstanceShaderBindingTableRecordOffsetEXT(rayQueryEXT q, bool committed);
but that was incorrectly getting translated to SPIRV as an `int`, and this was
causing SPIR-V validation errors when used.
Added explicit testing for the return types of all the builtin functions in GL_EXT_ray_query
* Add ray query capability if acceleration structure used
Fixes#2430
in non-ray tracing stages and the extension is enabled
* Add ray query capability if ray query declared
* Fix printing of TypeRayQueryKHR
It's no longer spelled with "Provisional"
* Fix traceRay/executeCallable to have id instead of constant.
Update to final (non-provisional) SPIR-V capabilities
(includes review feedback)
- Change visibilty of findLinkerObjects.
See merge request GLSL/glslang!78
* Add support for OpConvertUToAccelerationStructureKHR.

Vulkan Issue #2268
* Add testing for layouts on SBT

Use of gl_Layer and gl_ViewportIndex in tessellation and vertex
shaders should not trigger the addition of the Geometry capability.
Fixes#2461
Added tests for use of gl_Layer and gl_ViewportIndex in a tessellation
evaluation shader.
Several tests for NVIDIA features for tessellation, vertex, or mesh
shaders now lose the Geometry or MultiViewport capabilities.
This is ok because the functionality is already covered by
the ShaderViewportIndexLayerNV capability.
The spv.meshShaderPerViewBuiltins.mesh test now fails validation
because the validator does not know that PrimitiveId (and possibly
other) builtins are enabled by the MeshShadingNV capability.
I filed https://github.com/KhronosGroup/SPIRV-Headers/issues/179 to
fix the grammar upstream.
* Implement GL_EXT_terminate_invocation.
* terminateInvocation: declare the SPV extension
* Update test results for spirv-tools and bison version bumps
