* SPIR-V 1.4 headers, add SPV_ENV_UNIVERSAL_1_4
* Support --target-env spv1.4 in help for command line tools
* Support asm/dis of UniformId decoration
* Validate UniformId decoration
* Fix version check on instructions and operands
Also register decorations used with OpDecorateId
* Extension lists can differ between enums that match
Example: SubgroupMaskEq vs SubgroupMaskEqKHR
* Validate scope value for Uniform decoration, for SPIR-V 1.4
* More unioning of exts
* Preserve grammar order within an enum value
* 1.4: Validate OpSelect over composites
* Tools default to 1.4

Add asm/dis tests for OpCopyMemorySized
Requires grammar update to add second optional memory access operand
to OpCopyMemory and OpCopyMemorySized
* Validate one or two memory accesses on OpCopyMemory*
* Check av/vis on CopyMemory source and target memory access
This is a proposed rule. See
https://gitlab.khronos.org/spirv/SPIR-V/issues/413

* Add 1.4 validation for pointer comparisons
* New tests
* Validate with image operands SignExtend, ZeroExtend
Since we don't actually know the image texel format, we can't fully
validate. We need more context.
But we can make sure we allow the new image operands in known-good
cases.

* FIX: test case for hlsl functionality1
* Validation test fixture: ease debugging
* Use binary version for SPIR-V 1.4 specific features
* Switch checks based on the SPIR-V version from the target environment
to instead use the version from the binary
* Moved header parsing into the ValidationState_t constructor (where
version based features are set)
* Added new versions of tests that assemble a 1.3 binary and validate a
1.4 environment
* Fix test for update to SPIR-V 1.4 headers
* Fix formatting
* Ext inst lookup: Add Vulkan 1.1 env with SPIR-V 1.4
* Update spirv-val help
* Operand version checks should use module version
Use the module version instead of the target environment version.
* Fix comment about two-access form of OpCopyMemory
* Remove use of deprecated googletest macro
INSTANTIATE_TEST_CASE_P has been deprecated. We need to use
INSTANTIATE_TEST_SUITE_P instead.
* Remove extra commas from test suites.
Restrict capabilities to WebGPU spec
This covers whitelisting Matrix, Shader, Sampled1D, Image1D,
DerivativeControl, and ImageQuery. These are the allowed capabilities
that don't require an extension. Whitelisting VulkanMemoryModelKHR
will be handled by whitelisting its extension in a seperate patch.
Fixes#2101
* Check rules from Execution Mode tables, 2.16.2 and the Vulkan
environment spec
* Allows MeshNV execution model with the following execution modes
* LocalSize, LocalSizeId, OutputPoints and OutputVertices
* Done to not break their validation
Many of the files have using std::<foo> statements in them, but then the
use of <foo> will be inconsistently std::<foo> or <foo> scattered
through the file. This CL removes all of the using statements and
updates the code to have the required std:: prefix.
Also add a corresponding check for capabilities in the validator.
Update previously existing test cases where an instruction used to fail
assembling because of a version check, but now they succeed because the
instruction is also guarded by a capability. Now it should assemble.
Add tests to ensure that capabilities are checked appropriately.
The explicitly reserved instructions OpImageSparseSampleProj*
now assemble, but they fail validation.
Fixes#1624
- Fix tests for basic group operations (e.g. Reduce) to allow for
new capabilities in SPIR-V 1.3 that enable them.
- Refactor operand capability check to avoid code duplication and
to put all checks that don't need table lookup before any table
lookup.
- Test round trip assembly/disassembly support for extension
SPV_NV_viewport_array2
- Test assembly and validation of decoration ViewportRelativeNV
Fixes#1596
Added a framework for validation of BuiltIn variables. The framework
allows implementation of flexible abstract rules which are required for
built-ins as the information (decoration, definition, reference) is not
in one place, but is scattered all over the module.
Validation rules are implemented as a map
id -> list<functor(instrution)>
Ids which are dependent on built-in types or objects receive a task
list, such as "this id cannot be referenced from function which is
called from entry point with execution model X; propagate this rule
to your descendants in the global scope".
Also refactored test/val/val_fixtures.
All built-ins covered by tests
Previously we keep a separate static grammar table for opcodes/
operands per SPIR-V version. This commit changes that to use a
single unified static grammar table for opcodes/operands.
This essentially changes how grammar facts are queried against
a certain target environment. There are only limited filtering
according to the desired target environment; a symbol is
considered as available as long as:
1. The target environment satisfies the minimal requirement of
the symbol; or
2. There is at least one extension enabling this symbol.
Note that the second rule assumes the extension enabling the
symbol is indeed requested in the SPIR-V code; checking that
should be the validator's work.
Also fixed a few grammar related issues:
* Rounding mode capability requirements are moved to client APIs.
* Reserved symbols not available in any extension is no longer
recognized by assembler.
include: Add target environment enums for OpenCL 1.2 and 2.0
Validator: Validate OpenCL capabilities
Update validate capabilities to handle embedded profiles
Add test for OpenCL capabilities validation
Update messages to mention the OpenCL profile used
Re-format val_capability_test.cpp
Re-formatted the source tree with the command:
$ /usr/bin/clang-format -style=file -i \
$(find include source tools test utils -name '*.cpp' -or -name '*.h')
This required a fix to source/val/decoration.h. It was not including
spirv.h, which broke builds when the #include headers were re-ordered by
clang-format.
According to the SPIRV Spec (2.16.1):
* There is at least one OpEntryPoint instruction, unless the Linkage
capability is being used.
* No function can be targeted by both an OpEntryPoint instruction and an
OpFunctionCall instruction.
Also updated unit tests to includ OpEntryPoint.
This is described in Section 2.17 of the SPIR-V Spec.
* Updated existing unit test 'SemanticsIdIsAnIdNotALiteral' to pass by
manipulating the ID bound in its binary header.
* Fixed boundary check in the code.
* Added unit test to check the case that the largest ID is equal to the
ID bound.
These rules are under "Data Rules" in 2.16.1 (Universal Validation
Rules) part of the SPIR-V 1.1 Specification document:
* Scalar floating-point types can be parameterized only as 32 bit, plus
any additional sizes enabled by capabilities.
* Scalar integer types can be parameterized only as 32 bit, plus any
additional sizes enabled by capabilities.
* Vector types can only be parameterized with numerical types or the
OpTypeBool type.
* Matrix types can only be parameterized with floating-point types.
* Matrix types can only be parameterized as having only 2, 3, or 4
columns.
* Specialization constants (see Specialization) are limited to integers,
Booleans, floating-point numbers, and vectors of these.
