Add tests for matrix type data rule validation
This covers the data rules for matrix types specified in the SPIR-V
spec, section 2.16.1, and the WebGPU SPIR-V Execution Environment
spec.
Fixes#2065Fixes#2080
In logical addressing mode, we are not allowed to generate variables
pointers. There is already a check for OpSelect. However, OpPhi
and OpPtrAccessChain are not checked to make sure it does not
generate an variable pointer. I've added those checks.
Fixes#1957.
* MakePointerVisibleKHR cannot be used with OpStore
* MakePointerAvailableKHR cannot be used with OpLoad
* MakePointerAvailableKHR and MakePointerVisibleKHR both require
NonPrivatePointerKHR
* NonPrivatePointerKHR is limited to a subset of storage classes
* many tests
* 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
* Validate all type ids.
The validator does not check if the type of an instruction is actually
a type unless the OpCode has a specific requirement. For example,
OpFAdd is checked, but OpUndef is not.
The commit add a generic check that if there is a type id then the id
defines a type.

* Merge other checks for type into new one.
There are a couple check that the type id is a type for specific
opcodes. Those have been mereged into 1.
Small changes to other test cases to make them valid enough for the
purpose of the test.
In the specification of `OpTypeFunction`, it says
> OpFunction is the only valid use of OpTypeFunction.
This commit add a check in the validator for this rule.
A test started to fail because the new check happens before the check
the test case is testing. Updated the test case to still fail the
check it was suppose to fail originally.

* Split constant opcode validation out of idUsage and into
validate_constants.cpp
* minor style fixes
* reduced duplication
* fixed an issue with array sizing
* Moved function opcode validation out of idUsage and into new files
* minor style changes
* General opcode checking is in validate_function.cpp
* Execution limitation checking is in
validate_execution_limitations.cpp
* Execution limitations was split into a new pass as it requires other
validation to register those limitations first.
* Changed entry point validation to check storage class of variable
instead of pointer
* added a test
* Moved several checks after opcode validation
* These checks should be able to guarantee individual instructions are
ok
* Updated tests due to reordered checks
* Moved type instruction validation out of validation idUsage into a new
file
* Consolidate type unique pass into new file
* Removed one bad test
* Reworked validation ordering
Fixes#1800
* Refactored duplication of code between OpCopyMemory and
OpCopyMemorySized validation
* Fixed some bugs in OpCopyMemorySized validation
* Replaced asserts with checks
* Added new tests
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.
This CL updates the code to pull a valid instruction for the line number
when outputting a component error in OpVectorShuffle. The error line
isn't the best at this point as it points at the component, but it's
better then a -1 (turning to max<size_t>) that was being output.
The error messages has been updated to better reflect what the error is
attempting to say.
Issue 1719.
This CL updates the validate_id code to output the name of the object along with
the id number. There were a few instances which already output the name, this
just extends to all of them. Now, the output should say 123[obj] instead of just
123.
Issue #1581
In HLSL structured buffer legalization, pointer to pointer types
are emitted to indicate a structured buffer variable should be
treated as an alias of some other variable. We need an option to
relax the check of pointer types in logical addressing mode to
catch other validation errors.
1. Added OpCompositeExtract/Insert out of bounds checks where possible
(everything except RuntimeArray)
2. Moved validation of OpCompositeExtract/Insert from validate_id.cpp to
validate_composites.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.
There are a number of users of spriv-opt that are hitting errors
because of stores with different types. In general, this is wrong, but,
in these cases, the types are the exact same except for decorations.
The options is "--relax-store-struct", and it can be used with the
validator or the optimizer.
We assume that if layout information is missing it is consistent. For
example if one struct has a offset of one of its members, and the other
one does not, we will still consider them as being layout compatible.
The problem will be if both struct has and offset decoration for
corresponding members, and the offset are different.
The pass checks correctness of operands of instruction in opcode range
OpConvertFToU - OpBitset.
Disabled invalid tests
Disabled UConvert validation until Vulkan CTS can catch up.
Add validate_conversion to Android.mk
Also remove duplicate entry in CMakeLists.txt.
If the variable_pointer extension is used:
* OpLoad's pointer argument may be the result of any of the following:
* OpSelect
* OpPhi
* OpFunctionCall
* OpPtrAccessChain
* OpCopyObject
* OpLoad
* OpConstantNull
* Return value of a function may be a pointer.
* It is valid to use a pointer as the return value of a function.
* OpStore should allow a variable pointer argument.
The assembler assigns ID numbers sequentially, so it's confusing
to have a %1 in the source assembly when it isn't the first mentioned
ID. Rewrite the ID names to avoid this situation in a few cases.
From the SPIR-V Spec 2.16.1:
A function declaration (an OpFunction with no basic blocks), must have
a Linkage Attributes Decoration with the Import Linkage Type.
A function definition (an OpFunction with basic blocks) cannot be
decorated with the Import Linkage Type.
The limit for the number of struct members is parameterized using
command line options.
Add --max-struct-depth command line option.
Add --max-switch-branches command line option.
Add --max-function-args command line option.
Add --max-control-flow-nesting-depth option.
Add --max-access-chain-indexes option.
It is best to check the error messages of unit tests that fail
validation. This will ensure that a validation failure is due to what we
expect and not due to some secondary reason.
Updating SPIR-V Validator unit tests with error message checks.
When applied to a structure-type member, all members of that structure
type must also be decorated with BuiltIn. (No allowed mixing of built-in
variables and non-built-in variables within a single structure.)
When applied to a structure-type member, that structure type cannot be
contained as a member of another structure type.
There is at most one object per Storage Class that can contain a
structure type containing members decorated with BuiltIn, consumed per
entry-point.
