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.
Upgrade to VulkanKHR memory model
* Converts Logical GLSL450 memory model to Logical VulkanKHR
* Adds extension and capability
* Removes deprecated decorations and replaces them with appropriate
flags on downstream instructions
* Support for Workgroup upgrades
* Support for copy memory
* Adding support for image functions
* Adding barrier upgrades and tests
* Use QueueFamilyKHR scope instead of device
* Move ProcessFunction* function from pass to the context.
There are a few functions that are used to traverse the call tree.
They currently live in the Pass class, but they have nothing to do with
a pass, and may be needed outside of a pass. They would be better in
the ir context, or in a specific call tree class if we ever have a need
for it.
* Don't inline recursive functions.
Inlining does not check if a function is recursive or not. This has
been fine as long as the shader was a Vulkan shader, which forbid
recursive functions. However, not all shaders are vulkan, so either
we limit inlining to Vulkan shaders or we teach it to look for recursive
functions.
I prefer to keep the passes as general as is reasonable. The change
does not require much new code in inlining and gives a reason to refactor
some other code.
The changes are to add a member function to the Function class that
checks if that function is recursive or not.
Then this is used in inlining to not inlining a function call if it calls
a recursive function.
* Add id to function analysis
There are a few places that build a map from ids to Function whose
result is that id. I decided to add an analysis to the context for this
to reduce that code, and simplify some of the functions.
* Add missing file.
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
* Added a reduction pass to replace ids with ids of the same type that dominate them.
* Introduce helper method for querying whether an operand type is an input id.
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
We had a test that checks that a spirv binary where the depth of the
deepest nested construct is just below the default limit. This test
would take a long time causing a timeout in some builds. We are
questioning the value of the test since we already have a test that can
tell us if we are within a custom limit. We will remove the test.
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
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
That function currently only handled OpPtrAccessChain if it was in the
middle of the chain, but not at the start. Fixing that up.
Fixes crbug.com/905271.
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.
* Add base and core bindless validation instrumentation classes
* Fix formatting.
* Few more formatting fixes
* Fix build failure
* More build fixes
* Need to call non-const functions in order.
Specifically, these are functions which call TakeNextId(). These need to
be called in a specific order to guarantee that tests which do exact
compares will work across all platforms. c++ pretty much does not
guarantee order of evaluation of operands, so any such functions need to
be called separately in individual statements to guarantee order.
* More ordering.
* And more ordering.
* And more formatting.
* Attempt to fix NDK build
* Another attempt to address NDK build problem.
* One more attempt at NDK build failure
* Add instrument.hpp to BUILD.gn
* Some name improvement in instrument.hpp
* Change all types in instrument.hpp to int.
* Improve documentation in instrument.hpp
* Format fixes
* Comment clean up in instrument.hpp
* imageInst -> image_inst
* Fix GetLabel() issue.
If there is only 1 return and it is in a loop, then the function cannot be inlined.
Fix condition when inlined code needs one-trip loop wrapper. The dummy loop is needed when there is a return inside a selection construct. Even if there is only 1 return.
* 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.
