Fixes#2793
* Don't special case matrix validation compared to other composites
* just check the constituents are constants or undefs
* later checking validates the column type
* new test
* Process OpDecorateId in ADCE
When there is an OpDecorateId instruction that is live,
the ids that is references must be kept live. This change
adds them to the worklist.
I've also updated a validator check to allow OpDecorateId
to be able to apply to decoration groups.
Fixes#1759.
* Remove dead code.
This change refactors all storage class validation for atomics
to reflect the similar refactoring in the specification.
It is currently not possible to write a test for the check
rejecting Generic in an OpenCL 1.2 environment as the required
GenericPointer capability isn't allowed there. I've decided
to keep the check nonetheless to guard against the capability
becoming available without the rules for atomics being updated.
The ID changes in existing tests aren't ideal but introducing
names drags in a substantial refactoring of this file.
Contributes to #2595.

Fixes#2669
* Check capabilities when validating variables
* validate load and store types
* Constant check
* Don't checks pointers for stores, constants and loads
* Validate composite instructions
* Validate conversions for 8- and 16-bit limited types
* Unified tests and expanded them
* Disallow OpCopyMemory
* new tests and update old tests
* Can only be used with Vulkan memory model
* Can only be used with atomics
* Bit setting must match for compare exchange opcodes

generally with CooperativeMatrixNV
Also add a Builtin test generator variant that takes
capabilities and extensions.
Tests
- verify that the SMCountNV, SMIDNV, WarpsPerSMNV, and WarpIDNV Builtins are
accepted as Inputs in Vertex, Fragment, TessControl, TessEval, Geometry,
and Compute.
- verify that the SMCountNV, SMIDNV, WarpsPerSMNV, and WarpIDNV Builtins are
accepted as Inputs in MeshNV and TaskNV shaders.
- verify that the SMCountNV, SMIDNV, WarpsPerSMNV, and WarpIDNV Builtins are
accepted as Inputs in the 6 ray tracing stages
- verify that the SMCountNV, SMIDNV, WarpsPerSMNV, and WarpIDNV Builtins are
NOT accepted as Outputs.
- verify that the SMCountNV, SMIDNV, WarpsPerSMNV, and WarpIDNV Builtins are
NOT accepted as non-scalar integers (f32, uvec3)
- verify that the SMCountNV, SMIDNV, WarpsPerSMNV, and WarpIDNV Builtins are
NOT accepted as non-32-bit integers (u64)
Fixes#2604
* Allow selection constructs to branch to the nearest selection merge
whose header is terminated by an OpSwitch
* Cleanup break and continue checks generally
* add tests
It is currently not possible to use an Image Format that is
not Unknown without requiring a capability forbidden by the
OpenCL environment. As such the validation of Image Format
currently leans on capability validation entirely.
Fixes#2592.

Validate structured exits from constructs
* Add checks that exits from a construct are valid
* Add Construct::IsStructuredExit()
* uses specific rules for each type of construct
* Added a test and check for #2213
* Adding tests for bad loop and continue exits
* Fix identification of continue block that prevented some selections
from having any blocks
* Make pointers to logically matching types interchangeable with option.
DXC will be generating code where the function parameters will be a more
generic type that the actual parameter. They should be logically
matching and the decorations of the actual parameter must be a superset
of the decorations of the formal parameter.
We want to accept this code with an options so that spirv-opt can then
inline and fix the type mismatch. We will accept this under a new
options `--before-hlsl-legalization`.
The new option will also imply `relax-logical-pointer` so that HLSL
frontends will need to use just the one more generic option.
Moved the |LogicallyMatches| to the validation state to make it
available in more places. Also added a parameter to have it check the
decorations. I did not do a separate function for the decorations
because checking the decorations involves making sure the types
logically match anyway.

* Use grammar last version
Fixes#2560
* Parse last version and use it in checks
* Update grammar header generation
* Fix NonWritable tests
* Fix check and add specific tests
Fixes#2555
* Fix a bug in validation where interfaces were considered non-unique
between different entry points targeting the same function
* added a test
* Update private to local pass to remove localized private variables
from entry point interfaces
* added tests
* 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

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

cases.

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

report.
