Allow LocalSizeId as a way of sizing compute workgroups where the
environment allows it. A command-line switch is also added to force
acceptance even where the environment would not otherwise allow it.
* Disallow loading a runtime-sized array
Fixes#4472
* Disallow loading a runtime-sized array or a composite containing one
* Refactor type traversal into a separate function used by both runtime
array checks and sized int/float checks
* Update invalid tests
* Validate SPV_KHR_workgroup_memory_explicit_layout
* Check if SPIR-V is at least 1.4 to use the extension.
* Check if either only Workgroup Blocks or only Workgroup non-Blocks
are used.
* Check that if more than one Workgroup Block is used, variables are
decorated with Aliased.
* Check layout decorations for Workgroup Blocks.
* Implicitly use main capability if the ...8BitAccess or
...16BitAccess are used.
* Allow 8-bit and 16-bit types when ...8BitAccess and ...16BitAccess
are used respectively.
* Update SPIRV-Headers dependency
Bump it to include SPV_KHR_workgroup_memory_explicit_layout.
* Add option to validate Workgroup blocks with scalar layout
Validate the equivalent of scalarBlockLayout for Workgroup storage
class Block variables from SPV_KHR_workgroup_memory_explicit_layout.
Add option to the API and command line tool.
* Add validation for ray tracing builtins
- Remove existing InstanceId testing that was combined with VertexId in awkward ways.
- Rather than adding a new set of functions for each ray tracing builtin, add
an error table that maps the builtin ID to the 3 common VUIDs for each builtin
(I could see this being extended for other builtins in the future).
- add F32 matrix validation function
- augment existing PrimitiveId validation to verify Input storage class for the
RT stages this is accepted in, and correct the list of stages that it is actually
accepted in (only Intersection / Any Hit / Closest Hit)
* add testing for ray tracing builtins
- remove exising InstanceId testing as it was tangled in with VertexId in now weird ways
and combine it with the new tests
- add testing for ray tracing builtins
- builtins accepted in the same stages and of the same types are combined into test functions
- add some new matrix types to the code generator so they can be used for testing
in 3943 the new tests should have failed, but didn't due to the AnyVUID
check not handling case with trailing whitespace. Added trimming to handle
it as easily might happen again in future
Currently the validator, when checking an instruction is in the correct
section, always advances the current section. This means if we have an
instruction from a previous section we'll end up reporting it as invalid
in a function definition. This error is confusing.
This CL updates the validator to check if the given opcode is from a
previous layout section before advancing the current section. If it is
from a previous layout section an error is emitted.
The Vulkan 1.2.152 headers/spec now include Valid Usage IDs (VUID)
for every BuiltIn. This change adds labeling to help aid tracking
the coverage gap in Vulkan targeted validation. This is done with
a script in the Validation Layers that parses the source for VUID
strings, both that there is an implementation and a test for it.
There are 2 main changes:
1. A VUID string is added where applicable. It is wrapped in a function
that at runtimes checks if Vulkan is the target so that other targets
will not be effected as the output error only changes for Vulkan and
the overhead only occurs if there is an error at all.
2. For unit test, a new parameter value was added to allow make sure
that for each VUID there is a matching test. There are cases where the
same unit test checks multiple VUs via the parameter feature of gtest.
For this, I added a custom gMock Matcher to simply loop over a list
of VUID strings
Add support for SPV_KHR_non_semantic_info
This entails a couple of changes:
- Allowing unknown OpExtInstImport that begin with the prefix `NonSemantic.`
- Allowing OpExtInst that reference any of those sets to contain unknown
ext inst instruction numbers, and assume the format is always a series of IDs
as guaranteed by the extension.
- Allowing those OpExtInst to appear in the types/variables/constants section.
- Not stripping OpString in the --strip-debug pass, since it may be referenced
by these non-semantic OpExtInsts.
- Stripping them instead in the --strip-reflect pass.
* Add adjacency validation of non-semantic OpExtInst
- We validate and test that OpExtInst cannot appear before or between
OpPhi instructions, or before/between OpFunctionParameter
instructions.
* Change non-semantic extinst type to single value
* Add helper function spvExtInstIsNonSemantic() which will check if the extinst
set is non-semantic or not, either the unknown generic value or any future
recognised non-semantic set.
* Add test of a complex non-semantic extinst
* Use DefUseManager in StripDebugInfoPass to strip some OpStrings
* Any OpString used by a non-semantic instruction cannot be stripped, all others
can so we search for uses to see if each string can be removed.
* We only do this if the non-semantic debug info extension is enabled, otherwise
all strings can be trivially removed.
* Silence -Winconsistent-missing-override in protobufs
