There is inconsistencies between the different specs about whether or
not this capability is required/allowed, so tooling like glslang
currently ignores it. Once this is resolved the check and test can be
re-enabled.
* Only check for binding and descriptor set on variables that are
statically used by an entry point
* updated tests and added a couple new ones
* new method for collecting entry points that statically reference an
id
* Validate OpForwardPointer
The validator does not have a a check that OpForwardPointer is giving
a forward reference to a pointer type. We add that check.
https://crbug.com/910852
* Remove more specialized check.
There was a check that the forward pointer is actually a poiner type,
but it was only done if it was used in a struct. This was too specific.
Remove it in favour of the more general check that was added.
* Format
* Check the storage type in OpTypeForwardPointer
* Fix typo is test case epxected results.
Fixes#2147
* Checks that device scope is not used for availability and visibility
operations unless VulkanMemoryModelDeviceScopeKHR capability is present
* implemented for atomics, barriers and memory instructions currently
This CL changes the id/name output from the validator to always use a
consistent id[%name] style. This removes the need for getIdOrName. The
name lookup is changed to use the NameMapper so the output is consistent
with what the disassembler will produce.
Fixes#2137
* Validate uses of ids defined in unreachable blocks.
For some reason we do not make sure the uses of ids that are defined
in unreachable blocks are dominated by their def. This is causing
invalid code to pass the validator.
Fixes#2143
* Add test for unreachable code after a return.
We want to allow code like:
```
void foo() {
a = ...;
...
return; // for debugging
<use of a>;
...
}
```
I added a test to make sure that something like this is still accepted
by the validator.
* Add test for unreachable def used in phi.
Fixes#2104
* Checks the rules for logical addressing and variable pointers
* Has an out for relaxed logical pointers
* Updated PassFixture to expose validator options
* enabled relaxed logical pointers for some tests
* New validator tests
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
Fixes https://crbug.com/906669
* Don't free diagnostics in spvBinaryParse
* When invoking the parser we wish to ignore the error messages from,
instead create a hijacked context and replace the message consumer with
a null consumer
Make sure that initialized variable have correct storage class
For WebGPU and Vulkan environments, variables must have the storage
class; Output, Private, or Function, if they have an initializer.
Fixes#2071
Adding validation that the addressing declared by OpMemoryModel is
Logical and the memory model declared is VulkanKHR. Updating a bunch
of tests that were broken by this.
Fixes#2060
Check forbidden Annotation instructions for WebGPU env
From the WebGPU SPIR-V Execution Enviroment spec:
OpDecorationGroup, OpGroupDecorate, OpGroupMemberDecorate are not
allowed.
Fixes#2062
Validate that debugging instructions are not present for WebGPU
For WebGPU execution environments, check that all of the debug
instructions have already been stripped before validation.
Fixes#2063
Ban sequentially consistent with VulkanKHR
* Added validation check that SequentiallyConsistent memory semantics
are not used if the memory model is VulkanKHR
* Added tests
* Fixed a bug in evaluating constant 32-bit integers and updated some
handling to avoid inferring a value from a spec constant default
Remaining memory semantics validation
* Adds checks that OutputMemoryKHR, MakeAvailableKHR and MakeVisibleKHR
are only used if the VulkanMemoryModelKHR capabailty is present
* Added checks that MakeAvailableKHR requires release semantics
* Added checks that MakeVisibleKHR requires acquire semantics
* Added checks that MakeAvailableKHR and MakeVisibleKHR require a
storage class
Adds validator option to specify scalar block layout rules.
Both VK_KHR_relax_block_layout and VK_EXT_scalar_block_layout can be
enabled at the same time. But scalar block layout is as permissive
as relax block layout.
Also, scalar block layout does not require padding at the end of a
struct.
Add test for scalar layout testing ArrayStride 12 on array of vec3s
Cleanup: The internal getSize method does not need a round-up argument,
so remove it.
These are bookend passes designed to help preserve line information
across passes which delete, move and clone instructions. The propagation
pass attaches a debug line instruction to every instruction based on
SPIR-V line propagation rules. It should be performed before optimization.
The redundant line elimination pass eliminates all line instructions
which match the previous line instruction. This pass should be performed
at the end of optimization to reduce physical SPIR-V file size.
Fixes#2027.
From the Vulkan 1.1 spec 14.5.2:
Variables identified with the Uniform storage class are used to access
transparent buffer backed resources. Such variables must be typed as
OpTypeStruct, or an array of this type.
Fixes#1949
Validate variable types for UniformConstant storage in Vulkan (#2008)
From the Vulkan 1.1 spec 14.5.2:
Variables identified with the UniformConstant storage class are used
only as handles to refer to opaque resources. Such variables must be
typed as OpTypeImage, OpTypeSampler, OpTypeSampledImage, or an array
of one of these types.
Fixes#2008
The Vulkan specification does not permit use of the VertexId and
InstanceId BuiltIn decorations, so add a check to ensure they are not
being used when the target environment is Vulkan.
* Validate the id bound.
Validates that the id bound for the module is not larger than the max id
bound. Also adds an option to set the max id bound. Allows the
optimizer option to set the max id bound to also set the id bound for
the validation run done by the optimizer.
Fixes#2030.
The SPV_KHR_8bit_storage extension does not permit 8-bit integers to be
cast directly to floating point types. We are seeing shaders in the
wild, being produced by toolchains like glslang, that are generating
invalid SPIR-V.
This change adds validation to check for the patterns not permitted, and
some tests that expose the failure.
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
* Validation checks for new image operands MakeTexelAvailableKHR and
MakeTexelVisibleKHR
* added tests
* Tests that NonPrivateTexelKHR is accepted for all image operands
Updating test environments
* fixed build errors
* changed image types for *FetchSuccess tests to use a type defined in
1.3 shader body
This commit checks the following when Shader capability exists:
"The FPRoundingMode decoration can be applied only to a width-only
conversion instruction that is used as the Object operand of an
OpStore storing through a pointer to a 16-bit floating-point object
in the StorageBuffer, Uniform, PushConstant, Input, or Output
Storage Classes.".
This commit will change the message for unknown extensions from an error
to a warning.
Code was added to limit the number of warning messages so that consummer
of the messages are not overwhelmed. This is standard practice in
compilers.
Many other issues were found at while looking into this. They have been
documented in #1950.
Fixes http://crbug.com/875547.
* 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
OpPhi instruction must appear before all non-OpPhi instructions
except for OpLine. Without this commit, Validator does not check
the case that an OpPhi is preceeded by an OpLine and the OpLine is
preceeded by a non-OpPhi instruction that is not OpLine.
Checked all instructions whose object is OpTypeSampledImage or
OpTypeImage as suggested in #487. OpImageTexelPointer instruction
is missing and others look good. This commit adds only
OpImageTexelPointer.
We currently register decorations in the first pass through the
instructions. This is a problem because the validator has not even
checked if the decoration instructions are valid yet. This can lead to
unexpected behaviour from these side table. For example, in
https://github.com/KhronosGroup/SPIRV-Tools/issues/1882, we use 5GB of
data to store 1 decoration for ids that are not even defined.
Fixes https://github.com/KhronosGroup/SPIRV-Tools/issues/1882.
Support collapsed into one commit:
- Asm/Dis support for SPV_KHR_vulkan_memory_model
- Add Vulkan mem model image operands to switch
- Add TODO for source/validate_image.cpp
- val: Image operands NonPrivateTexelKHR, VolatileTexelKHR have no operands
This is required for memory model tests to pass SPIR-V validation.
- Round trip tests: Test new flags on OpCopyMemory*
* 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.
http://crbug.com/876694
* 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
When doing the validator checks, an instruction is currently registered
at the end of IdPass. This creates an inconsistency. In IdPass, an
instruction that uses its own result will treat that use as a forward
reference. Then in the following passes it will not because the
definition can be found.
It seems best to update the state after all of the check have been done
for the current instruction. This makes it consistent for all of the
passes.
This makes a different when trying to verify OpTypeStruct.
Fixes https://crbug.com/874372.
The code in source/message was only used in a single set of tests to
format the output results. This CL changes the test to verify the
message instead of all the error values and removes the source/message
code.
* 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
* Replaced uses in opcode validation of current_function()
* Added non-const accessor to function lookup in ValidationState_t
* Updated a couple bad tests due to check reordering
When validating a FunctionCall we can trigger an assert if we are not
currently within a function body. This CL adds verification that we are
within a function before attempting to add a function call.
Issue 1789.
This CL moves most of the logic out of validation ProcessInstruction and
groups it into validate. This places all of the validation logic in the
same place making it clearer what is running.
The Instruction class is changed to allow setting the function and block
after creation.
This CL changes the stats aggregator to use
ValidateBinaryAndKeepValidationState to process the binary. This means
we can remove ValidateInstructionAndUpdateValidationState which expects
to be able to call ProcessInstruction in the validate anonymous
namespace. This decouples the stats aggregator from how validation
processes the binary.
The instruction counter is the same as the size of the
ordered_instruction list when we insert a new instruction. This Cl
removes instruction_counter_ and uses that instead.
* Refactored the Memory class of instructions in the spec out Id
validation and into a new pass
* Tests unmodified
* some minor disassembly changes
* minor style changes
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 removes the two diag() overloads and leaves only the version
which accepts an Instruction. This is safer as we never use the
implicit location from the validation state.
Several of the diag() calls in validate_decorations do not provide the
line number, and will output the last line in the file. This CL updates
the diag() calls to provide the instruction of interest.
This CL removes the two deque's from ValidationState and converts them
into std::vectors. In order to maintain the stability of instructions we
walk over the binary and counter the instructions and functions in the
ValidationState constructor and reserve the required number of items in
the module_functions_ and ordered_instructions_ vectors.
Issue #1176.
This CL updates the diag() calls in validate_cfg to provide the
associated instruction. This fixes a couple places where we output the
last line of the file instead of the instruction as the disassembly.
Previously the adjacency messages would output the last line of the file
as the disassembly. This is incorrect, as we have an instruction they
can be attached too. This CL fixes the messages to attach to the correct
line number.
This CL changes validate.cpp to use diag providing an explicit
instruction. This changes the result of the function end checks to not
output a disassembly anymore as printing the last line of the module
didn't seem to make sense.
This CL changes the signature of diag() to accept an Instruction instead
of the instructions position.
A deprecated variant that accepts the position is available but will be
removed in the near future.
Currently, some instructions will be missing from the list of
ordered_instructions. This will cause issues due to the debug change
which passed the last instruction into subsequent passes.
This CL moves the addition to the ordered list out of the
RegisterInstruction method into AddOrderedInstruction. This method is
called first in ProcessInstruction and the CapabilitiesPass and IdPass
are updated to take an Instruction parameter.
This CL removes the redundant operator name from the error messages in
validate_composites. The operator will be printed on the next line with
the disassembly.
This CL splits the switch in ImagePass into individual validate
functions. The error messages have been updated to drop the
suffix/prefix of the opcode name since it will be displayed in the
disassembly.
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.
When folding a vector shuffle that feeds another vector shuffle causes
the size of the first operand to change, when other indices have to be
adjusted reletive to the new size.
