When there is an array of strutured buffers, desc sroa will only split
the array, but not a struct type in the structured buffer. However,
the calcualtion of the number of binding a struct requires does not take
this into consideration. This commit will fix that.
Avoid generating OpPhi on void types, and allow the transformation to
take place on regions that produce pointer and sampled image result
ids if such ids are not used after the region.
Fixes#3787.
* validation: tighter validation of multisampled images
- if MS=1, then Sample image operand is required
- Sampling operations are not permitted when MS=1
Fixes#4057, #4058
* Fail early for multisampled image for sampling, dref, gather
This scripts fails to run in Python 2. For systems that have both
Python 2 and 3 installed, depending on your PATH the existing code may
or may not run. Explictly using Python 3 to avoid this.
* validate StorageImageMultisampled capability
The StorageImageMultisampled capability is required when declaring
an image type with with Multisampled==1 and it's a storage image (Sampled == 2)
Fixes#4061
* Allow SubpassData with Multisampled and Sampled==2
Similar to [1] DCE should be ran when this extension is enabled to
prevent unused bindings from showing up (in particular atomic counters
attached to buffers).

The eliminate dead member pass is written assuming that the index to an
OpAccessChain will be a 32-bit integer or 64-bit integer. That is
changed to work for any width 64-bits or less.

* Add validation for ray tracing builtins
- Remove existing InstanceId testing that was combined with VertexId in awkward ways.
- Rather than adding a new set of functions for each ray tracing builtin, add
an error table that maps the builtin ID to the 3 common VUIDs for each builtin
(I could see this being extended for other builtins in the future).
- add F32 matrix validation function
- augment existing PrimitiveId validation to verify Input storage class for the
RT stages this is accepted in, and correct the list of stages that it is actually
accepted in (only Intersection / Any Hit / Closest Hit)
* add testing for ray tracing builtins
- remove exising InstanceId testing as it was tangled in with VertexId in now weird ways
and combine it with the new tests
- add testing for ray tracing builtins
- builtins accepted in the same stages and of the same types are combined into test functions
- add some new matrix types to the code generator so they can be used for testing
This instruments ImageRead, ImageWrite and ImageFetch when applied to
texel buffers.
Also add new (but not yet generated) buffer OOB error codes differentiated
for VUID classification.
* BuildModule: optionally avoid adding new OpLine instructions
Fixes#4029 for my use case
* Fix formatting
* Create last_line_inst_ only if doing extra line tracking
* Update to final ray tracing extensions

MeshShadingNV: enables PrimitiveId, Layer, and ViewportIndex

Fix buffer oob instrumentation for matrix refs.
Matrix stride decoration is not on matrix type but is a member decoration
on the enclosing struct type. Also correctly apply matrix stride depending
on row or column major.
spirv-opt has a bug that `DebugInfoManager::AddDebugValueWithIndex()` does not
preserve `Indexes` operands of
[DebugValue](https://www.khronos.org/registry/spir-v/specs/unified1/OpenCL.DebugInfo.100.html#DebugValue).
It has to preserve all of those `Indexes` operands, but it preserves only the first index
operand.
This PR removes `DebugInfoManager::AddDebugValueWithIndex()` and lets the spirv-opt
use `DebugInfoManager::AddDebugValueForDecl()`.
`DebugInfoManager::AddDebugValueForDecl()` preserves the Indexes operand correctly.
Don't pass a constructed string as an argument to
ValidateNotCalledwithExecutionModel. That method is captured via
std::bind and it ends up using lots of stack space.
Instead, pass in:
- a Vulkan validation unique ID as an integer instead,
(with -1 meaning no VUID), and
- the const char* for the explanator text.
in 3943 the new tests should have failed, but didn't due to the AnyVUID
check not handling case with trailing whitespace. Added trimming to handle
it as easily might happen again in future
