Fixes #6171
This commit adds logic for reporting double support
to the d3d11 backend, for running tests on GPUs that
do not support D3D11_FEATURE_DOUBLES, and add checks
for that support to tests that require the feature.

* Add GetDimensions support for CUDA
This CL adds GetDimensions support for cuda by using the PTX
instructions. Currently, PTX only supports getting width, height and
depth.
This CL also adds a new test to test this support.
Fixes #5139

* Use and() and or() functions for logical-AND and OR
With this commit, Slang will emit function calls to `and()` and `or()`
for the logical-AND and logical-OR when the operands are non-scalar and
the target profile is SM6.0 and above. This is required change from
SM6.0.
For WGSL, there is no operator overloadings of `&&` and `||` when the
operands are non-scalar. Unlike HLSL, WGSL also don't have `and()` nor
`or()`. Alternatively, we can use `select()`.

* SP004: implement initialize list translation to ctor
- We synthesize a member-wise constructor for each struct follow
the rules described in SP004.
- Add logic to translate the initialize list to constructor invoke
- Add cuda-host decoration for the synthesized constructor
- Remove the default constructor when we have a valid member init constructor
- Disable -zero-initialize option, will re-implement it in followup (#6109).
- Fix the overload lookup issue
When creating invoke expression for ctor, we need to call
ResolveInvoke() to find us the best candidates, however
the existing lookup logic could find us the base constructor
for child struct, we should eliminate this case by providing
the LookupOptions::IgnoreInheritance to lookup, this requires
us to create a subcontext on SemanticsVisitor to indicate that
we only want to use this option on looking the constructor.
- Do not implicit initialize a struct that doesn't have explicit default
constructor.

* Don't treat StrcturedBuffer<IFoo> as a specializable param.
* Fix RHI.
|
|
|
|
Some tests are now passing and are enabled.
Other tests are still failing, but are given comments categorizing the failures.
Tests in the 'Not supported in WGSL' category are also removed from the expected failures
list. (Though they are still kept disabled for WebGPU, of course.)
This closes #5519.

targeting WGSL (#5483)
Structured buffer types translate to array types in the WGSL emitter.
WGSL doesn't allow passing runtime-sized arrays to functions.
Similarly for pointers to texture handles.
Also, structured buffers (runtime-sized arrays) cannot be returned in WGSL.
This closes issue #5228, issue #5278 and issue #5288 by enabling specialized functions
to be generated in these cases, in order to work around these constraints.

* Legalize the Entry-point for WGSL
The return type of the entry-point needs to be legalized when targeting
WGSL.
This commit flattens the nested-structs of the return type and the input
parameters of the entry-point.
Most of code is copied from the legalization code for Metal. The
following functions are exactly same to the implementation for Metal or
almost same.
- flattenInputParameters() : 136 lines
- reportUnsupportedSystemAttribute() : 7 lines
- ensureResultStructHasUserSemantic() : 46 lines
- struct MapStructToFlatStruct : 176 lines
- flattenNestedStructs() : 95 lines
- maybeFlattenNestedStructs() : 42 lines
- _replaceAllReturnInst() : 19 lines
- _returnNonOverlappingAttributeIndex() : 16 lines
- _replaceAttributeOfLayout() : 23 lines
- tryConvertValue() : 41 lines
- legalizeSystemValueParameters() : 11 lines
They need to be refactored to reduce the duplication later.
The test case, `tests/compute/assoctype-lookup.slang`, had a bug that
the compute shader was trying to use the varying input/output with the
user defined semantics.
This commit removes the user defined semantics, because the compute
shaders cannot use the user defined semantics.

This fixes a teardown crash, and a buffer usage mismatch issue during bind group creation.
These Slang-RHI fixes allow several WGPU tests to be enabled:
- tests/compute/column-major.slang
- tests/compute/constant-buffer-memory-packing.slang
- tests/compute/matrix-layout.hlsl
- tests/compute/non-square-column-major.slang
- tests/compute/row-major.slang
- tests/hlsl/packoffset.slang
This helps to address issue #5222.

* Use the assembly description as target when disassembling
I believe this is a bugfix.
It seems to have worked before because up until the WGSL case, the disassembler has been
the same executable as the one producing the binary to be disassembled.

This closes issue #5104.
* Add downstream compiler for Tint.
* Tint is wrapped in a shared library, 'slang-tint' available from [1].
* The header file for slang-tint.dll is added in external/slang-tint-headers.
* Add some boilerplate for WGSL targets.
* Add an entry point test for WGSL.

* Fix the issue that NonUniformResourceIndex is ignored
Fix the issue that after `specializeFunctionCalls`,
`NonUniformResourceIndex` is ignored in the generated specialized
function.
The reason is that if the function has a non-uniform resource parameter,
we will legalize it by replacing the resource parameter with a index,
and indexing of the resource will be moved inside the specialized function.
e.g.
```
void func(ResourceType resource) { ... }
func(resource[NonUniformResourceIndex(0)])
```
will be specialized into
```
void func(int index) { resource[index]; }
func(0);
```
In this case, inside the function, we will loose the information about
whether the resource is a non-uniform. So we add the handling for this
corner case by adding insert a `NonUniformResourceIndex` into the
specialized function:
```
void func(int index) {
int nonUniformIdx = NonUniformResourceIndex(index);
resource[nonUniformIdx];
}
```
* Fix the issue that arguments mismatch after specilization callsite
specializeCall() call could cause arguments mismatch with the parameters
of the specialized function.
For example, if the function parameter contains a resource type
```
void func(ResourceType res) { ... }
int index = ...
func(resources[index]);
```
This will be specialized into
```
void func(int index) { resources[index] }
int index = ...
func(index);
```
However, if we have more than 1 call sites, and the other call site
doesn't use `int` as the index, e.g.
```
uint index = ...
func(resources[index]);
```
this call site will be specialized into
```
uint index = ...
func(index);
```
this will be invalid, because the argument doesn't match the parameter.
so we just add the data type of the new arguments into the function key such that
For the uniformity info, we add a new attribute "IROp_NonUniformAttr",
so we will form a IRAttributedType that encodes both uniformity and data
type, and use it as the key of call info. So if there is call site using the different
data type for the resource index, we will specialize a new function for this.
* Handle the intCast and uintCast operation
Since after intCast/uintCast of nonuniformIndex, it's still a
nonuniformIndex. So we will handle this case as well.
Also, add a new test to cover this.

Closes #4746.
This commit adds a support for "NumThreads" and "Shader" attribute keyword, which is in CamelCasing starting with an upper case letter.
The attribute keywords in HLSL are case-insensitive. As an example, one of D3D documents says,
"The attribute name "Shader" is case insensitive."
https://microsoft.github.io/DirectX-Specs/d3d/WorkGraphs.html
Slang, however, doesn't support the case-insensitivity. They should be all lower-case or CamelCasing starting with an upper case.

column_major/row_major. (#4653)
* Allow CPP/CUDA/Metal to legalize their buffer-elements.
Fixes: #4537
Changes:
1. Matrix inputs require legalization (pack/unpack) to ensure consistent row_major/column_major throughout entire shader, the following enabled legalization pass fixes this.
2. Added missing CUDA intrinsic so CUDA can run more tests.
3. Added a memory packing test since this still fails for cpp/cuda/metal (due to having no memory packing enforcement).
* change memory packing tests to run for targets without packing

* Treat global variables and parameters as non-differentiable when checking derivative data-flow
Global parameters are by-default not differentiable (even if they are of a differentiable type), because our auto-diff passes do not touch anything outside of function bodies.
The solution is to use wrapper objects with differentiable getter/setter methods (and we should provide a few such objects in the stdlib).
Fixes: #3289
This is a potentially breaking change: User code that was previously working with global variables of a differentiable type will now throw an error (previously the gradient would be dropped without warning). The solution is to use `detach()` to keep same behavior as before or rewrite the access using differentiable getter/setter methods.
