Added a new command-line option: -fspv-debug=<category>, where
category can be file, source, line, and tool, to give developers
fine-grained control of what debug information they want in
the generated SPIR-V code.
format: -fvk-bind-register <type-number> <space> <binding> <set>
Also created a short alias for it: -vkbr.
This option gives the ultimate manual control of descriptor
assignment. It requires:
* All resources are annotated with :register() in the source code
* -fvk-bind-register is specified for every resource
It overrules all other mechanisms.
It cannot be used together with -fvk-{u|b|s|t}-shift.
Validate raytracing shader properties and RDAT blob part
- no signatures for ray tracing shader functions
- payload/params/attribute sizes are >= argument type allocation sizes
- RDAT is bit-identical to RDAT generated
- Minor fix for CS: should not have input signature elements either.
- update val version comment
- Prevent strange behavior with library target and entry point not empty.
- remove DXASSERT in LoadDxilMetadata (validation should catch this case)
This option reciprocates (multiplicatively inverts) SV_Position.w
after reading it from stage input in PS. This is used to accommodate
the difference between Vulkan and DirectX.
Finalize OpCode changes for Dxil 1.3 / SM 6.3
- Rename CreateHandleFromResourceStructForLib to CreateHandleForLib
- Add PrimitiveIndex
- Add final NumOp[Codes|Classes]_Dxil_1_3 values
- Fix legal shader stage set for PrimitiveID
Added -Wno-vk-ignored-features to suppress warnings on features
that are ignored because of no Vulkan support. Examples include
cbuffer member initializer.
2 means no indication as to whether this is a depth or non-depth
image.
Reverted "Hack OpSampledImage for depth-comparison sampling".
This reverts commit 0f165c6483.
It's actually a spec reading issue that it seems we cannot
have stand-alone variables for Position, PointSize, ClipDistance,
or CullDistance in HS/DS/GS.
Removed all code regarding Position and PointSize from GlPerVertex.
We still need to keep GlPerVertex aroudn to handle ClipDistance
and CullDistance though.
In HLSL, dual-source color blending is enabled only via API;
the shader needs no special marks: it only writes SV_Target0
& SV_Target1 like normal.
But in Vulkan, to enable dual-source blending, the shader need
to mark the two participating output variables with Index = 0
and Index = 1, respectively.
So we introduce a new attribute, vk::index(), to let developers
to specify the index of an output variable so dual-source
blending can be enabled.
See Vulkan spec "26.1.2. Dual-Source Blending".
GLSL as a shading language does not define the layout rules for
std140/std430; the OpenGL graphics environment defines that.
This is also more consistent with -fvk-use-dx-layout.
* [spirv] Add -fspv-target-env command line option.
The valid values for this option currently are:
vulkan1.0
vulkan1.1
If no target environment is specified, vulkan1.0 is used as default.
Added FeatureManager to record all extensions specified from
the command-line and emit error if trying to use one not permitted.
Added command-line option -fspv-extension= to specify
whitelisted extensions.
This commit uses the HlslCounterBufferGOOGLE decoration to link
the main RW/Append/Consume StructuredBuffer with its associated
counter buffer. It also uses HLSLSemanticGOOGLE to decorate
stage IO variables with their semantic strings from the source code.
In SPIR-V, if shifting a value by an amount that is greater than
the value's bitwidth, the result is undefined.
FXC and DXC/DXIL performs a bitwise and over the RHS of the shift
operation to only consider its (n - 1) least significant bits,
where n is the bitwidth of LHS.
