* Break down RecordReply to individual tests to avoid timeout
In Debug build, RecordReplay unit-test was timing out.
It was running six tests all in one unit-test, but this commit breaks it
down to individual test so that each unit test can be done within the
timeout limit.
This issue has seen only in Debug build but it has been unnoticed
because even when the test failed with test-server, it was still passing
on its retry because the time-out applies only when using test-server.
* Reduce the retry from 2 times to 1 time
* Remove RecordReplay from expected failure

When we return a raw point to a module, we should decrement the
reference count. The module is owned by its session so it should be
valid as long as the session is valid.

* Add a new slang-test option `-enable-debug-layers`
A variable `disableDebugLayer` is renamed to `enableDebugLayers`,
and a corresponding command-line argument is added,
`-enable-debug-layers`.
The previous option `-disable-debug-layer` is still available, but it
prints a deprecation warning message.
The reason why it is added is to make the option available to both Debug
and Release. On Debug build, it will be enabled by default, and it will
be disabled on Release build. We should be able to not only disable it,
but also enable it on Release build.
Ideally this option should be enabled all the time, but currently there
are too many VUID error messages printed and we are enabling only for
Debug build for now.
Note that the CI/CD will run with the option disabled until we resolve
all of VUID errors.

Previously when running slang-test with "-use-test-server" to run
slang-unit-test-tool and gfx-unit-test-tool tests, these would
fail with a message like, "error: Unable to launch tool". These issues
appear to have been resolved, however debug runs of gfx-unit-test-tool
using "-use-test-server" were still showing errors of the following
nature:
````
error: rpc failed
error: result code = -858993460
standard error = {
}
standard output = {
}
ignored test: 'gfx-unit-test-tool/uint16BufferTestVulkan.internal'
````
These errors all appeared to be the result of Vulkan VUID print outs
and were occuring for nearly every Vulkan test.
Existing comments in slang-test-main.cpp indicated that VUID print outs
get misinterpreted as the result from a test due to limitations in the
Slang RPC implementation. Slang-test then correctly disables use of VK
debug layers when the spawn type is UseTestServer. However, this argument
is only passed to the test server when running standard tests (see
ExecuteToolTestArgs vs ExecuteUnitTestArgs).
This change hard codes `unitTestContext.enableDebugLayers = false;` in
test-server-main.cpp when running unit tests, as otherwise this will
currently result in all Vulkan tests being ignored.
Additional tweaks were made to slang-test-main.cpp to restore the spawn
type for unit tests and to prevent bogus rpc error result codes.

* Add check for the variable requirement
This change adds the capability check for the variables requirement.
With this check, the shader
```
[require(cpp_cuda_glsl_hlsl_metal_spirv)]
Buffer<float> InputTyped;
[require(cpp_cuda_glsl_hlsl_metal_spirv)]
RWBuffer<float> OutputTyped;
```
will issue error if targeting to WSGL
e.g. `.\build\Debug\bin\slangc .\tests\wgsl_no_buffer.slang -o
wgsl_no_buffer.txt -target wgsl -entry Main -stage compute`
.\tests\wgsl_no_buffer.slang(2): error 36108: 'InputTyped' has dependencies that are not compatible on the required target 'wgsl'.
Buffer<float> InputTyped;
^~~~~~~~~~
.\tests\wgsl_no_buffer.slang(4): error 36108: 'OutputTyped' has dependencies that are not compatible on the required target 'wgsl'.
RWBuffer<float> OutputTyped;
^~~~~~~~~~~
Fixes #6304

The files `slang-fossil.{h,cpp}` define a new serialization format that is designed to support data being memory-mapped in and then traversed as-is.
The `docs/design/serialization.md` document was updated with details on this new format.
The `slang-serialize-fossil.{h,cpp}` files define implementations of the recently introduced `ISerializerImpl` interface for reading/writing this new binary format.
The overall structure of these implementations is heavily based on the existing RIFF implementation from `slang-serialize-riff.{h,cpp}`.
Switching the AST serialization over to use this format required almost no changes to `slang-serialize-ast.cpp`.
The new format is more space-efficient than the RIFF-based format in memory (by factor of over 2x), but is actually *worse* than the RIFF-based format in terms of how it affects the size of `slang.dll`, because the new format is seemingly less amenable to LZ4 compression.
A few pieces of utility code were added or moved as part of this work:
* The `core/slang-internally-linked-list.*` implementation is just a type that was used as part of `core/slang-riff.*`, but that wasn't really RIFF-specific.
* The `core/slang-blob-builder.*` files implement a low-level utility for building a binary format in memory out of "chunks". The overall structure of this type is based on the RIFF-specific builder implementation, but has been generalized so that it should apply to other kinds of binary serialization.
* The `core/slang-relative-ptr.h` file implements a simple relative pointer type, which is currently only used by the `slang-fossil.h` format.
If there are concerns about adopting the new format immediately for the AST, this change could be modified to introduce all the new code, but leave the AST serialization using the previous RIFF-based format.

* Enable LSS hit object test
Enabled LSS SER tests now that PR #7211, which added SER support to OptiX,
has been merged.
Ran: ./build/Debug/bin/slangc.exe tests/cuda/lss-test.slang -target ptx
-Xnvrtc -I"C:/ProgramData/NVIDIA Corporation/OptiX SDK 9.0.0/include"
and confirmed that the HitObject intrinsic is called.
eg:
call (%f15, %f16, %f17, %f18, %f19, %f20, %f21, %f22),
_optix_hitobject_get_linear_curve_vertex_data, ();

The `SLANG_UNREFLECTED` macro has been completely meaningless since we switched away from the old AST serialization/reflection approach, so the lingering uses of it in the code as pointless at best and misleading/confusing at worst.

* Fix operator precedence in OptiX ray payload pointer casting
Added extra parentheses around the cast to ensure proper operator precedence when
dereferencing the OptiX ray payload pointer. This fixes the issue where the compiler
was treating the expression as (RayPayload_0 *)getOptiXRayPayloadPtr()->color_0 instead of
((RayPayload_0 *)getOptiXRayPayloadPtr())->color_0.
Error:
nvrtc 12.9: tests/cuda/optix-cluster.slang(17): error : expression
must have pointer-to-class type but it has type "void *"
nvrtc 12.9: note : (RayPayload_0
*)getOptiXRayPayloadPtr()->color_0 = color_1;
nvrtc 12.9: note : ^
Tested using:
./build/Debug/bin/slangc -target ptx -Xnvrtc
-I"/home/haaggarwal/NVIDIA-OptiX-SDK-9.0.0-linux64-x86_64/include"
-DSLANG_CUDA_ENABLE_OPTIX -entry closestHitShaderA

2. Implemented core SER functionality (TraceRay, MakeHit/Miss, Invoke)
3. Added OptiX-specific hit object handling functions
4. Added test case for OptiX SER functionality

* Add default constructor for Ptr type

* Implement default initializer list for C-Style type member
Close #6189.
Previsouly, for the C-Style member in a struct, if it doesn't have any initialize
expression, when we synthesize the ctor, we will not associate the
default value for the parameter corresponding to that member.
This bring some trouble that existing slang users has to add '= {}' to
every struct fields in order to make all the parameters in the synthesized ctor having
a default value, so people can still use `Struct a = {}` to create a
struct.
To make this use case convenience, we will automatically associated a
'= {}' as the default value for this case.
This PR also add support for empty initializing link-time sized vector/matrix by "= {}".
In addition, this PR also fix a bug in auto diff where we should not report error when proccessing
transpose on an empty struct.

fixes: [#7143](https://github.com/shader-slang/slang/issues/7143)
fixes: [#7146](https://github.com/shader-slang/slang/issues/7146)
Goal of PR:
* This PR is part of the larger #7115 refactor to how dynamic dispatch works.
* The first step is to add the `-std <std-revision>` flag.
* The second step is to provide basic `dyn` keyword support in AST. This does not include `varDecl` support since most of these interactions require `some` keyword support.
Future PR(s) goal:
* Support `some` keyword in AST. With this we will also implement all varDecl interactions between `dyn` and `some`.
* Add IR support for `some` and `dyn`.
Breakdown of PR:
* most of the logic is in `validateDyn.*`. This was done so that in the future when we implement more features we will have an easy time removing/adding restrictions to `dyn` interfaces.
Breaking changes:
* As per spec (https://github.com/shader-slang/spec/pull/14/files), any type conforming to a `dyn` interface errors if member list contains one of the following: opaque type, non copyable type, or unsized type.
* Due to the breaking change, the test `tests\compute\dynamic-dispatch-bindless-texture.slang` is incorrect. This has been fixed.
|
|
* Fix incorrect way of type checking inside of CoopVec Multiply
Related to an issue #7201.
The operator `is` is silently failing when the right-hand-side operand is an interface type.
This PR uses concrete types to check the type.

* Add inverse hyperbolic derivatives
* Add test
|
|
This change takes the new approach to serialization that was used for the AST and generalizes it in a few ways:
* The new approach is no longer tangled up with the RIFF format.
The serialization system supports multiple different implementations of the underlying format.
The existing RIFF format is now supported as one back-end, but support for others will follow in subsequent changes.
* The new approach is no longer deeply specialized to AST serialization.
The old code had things like serialization for `List`s and `Dictionary`s, but it was embedded inside the `AST{Encoding|Decoding}Context`, and thus couldn't be leveraged for other serialization tasks.
This change factors out a completely AST-independent `Serializer` implementation, with an `ASTSerializer` layered on top of it to provide the additional context needed.
* There is less duplication of code between reading and writing of serialized data.
The old code had both the `ASTEncodingContext` and `ASTDecodingContext`, with serialization logic for most types being implemented in both, but with the constraint that those implementations needed to be kept in sync to avoid serialization-related runtime failures.
A key property of the revamped approach is that a single `serialize()` method for a type implements both the reading and writing directions of serialization.
