CompilerOptionName::EmitSpirvViaGLSL and CompilerOptionName::EmitSpirvDirectly
options are not mutually exclusive, but due to compatible reason, we
cannot delete those options. Instead, this change makes the effort to
create a new option name EmitSpirvMethod, and we will turn those two
options into the new one internally. Also, we put a priority implicitly
on those two options, where EmitSpirvDirectly always win if it's set.
We have another location that can setup the same option, where is
through SlangTargetFlags::SLANG_TARGET_FLAG_GENERATE_SPIRV_DIRECTLY.
We should definitely deprecate this flag to avoid more confusing.
But for the same compatible reason, we cannot do that in this PR.
Again, we will encourage people to not use this flag, but using the
CompilerOptionName instead. In this PR, we will also implicitly give
CompilerOptionName higher priority, it means that as long as user setup
the CompilerOptionName for emit spirv method, it always take higher
priority for the final decision.

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.

This helps to address issue #5222.
Also disable Slang-RHI from fetching DXC and Agility SDK, since that seems to break our
tests. (See issue #5474.)

* Precompiled SPIR-V import support
Adds appropriate linkage and function declaration syntax
for SPIR-V functions that are declared, to be imported
from another SPIR-V module.
Unlike DXIL, stripping the Slang IR for a function down
to a declaration requires retaining a block of parameters,
as the function declaration must be emitted to SPIR-V
with the same parameters as a definition. Because that
thwarts the logic in Slang to tell the difference between
a declaration and definition, and explicit decoration is
introduced to explicitly mark functions which need to be
treated as declarations during emit phase.
Fixes #4992

* Use Offset instead of ConstOffset for GLSL function textureGatherOffset
This commit changes to use `Offset` option on OpImageGather instruction
when translating `textureGatherOffset` to SPIR-V code.
Interestingly GLSL allows the offset value to be a variable not
constant just for the function `textureGatherOffset` while all other
offset variants of texture sampling functions require the offset to be a
constant value.
From a few experiments, I found that the spirv-optimizer changes
`Offset` to `ConstOffset` if the offset is a compile-time value. I also
found that when the offset value is zero, it changes to `None` with no
offset value.

(#5415)
This commit changes the word "stdlib" or "standard library" to "core module" in the source code.
|
|
The directory name of `source/slang-stdlib` is changed to `source/slang-core-module`.
We will use the term "core module" instead of "standard library" from now on.

* Add documentation for buffer types

* Update doc for LoadxAligned functions
Update the doc for all Load{2,3,4}Aligned and LoadxAligned<T> functions of
buffer type. We assume that those aligned version of Load{2,3,4} and
Load<T> will treat the whole buffer as type of unit{2,3,4} or T,
so the address must be aligned to size of the loaded type.

This commit renames the files and projects to prefer "core-module" over
"stdlib".
The directory name `source/slang-stdlib` needs to be renamed too, and
there will be another commit for it soon.
|
|
This is a breaking change in a way that the Slang API function names are changed. All of them are commented as "experimental" and we wouldn't provide a back-ward compatibility for them.
Following functions are renamed:
compileStdLib() -> compileCoreModule()
loadStdLib() -> loadCoreModule()
saveStdLib() -> saveCoreModule()
slang_createGlobalSessionWithoutStdLib() -> slang_createGlobalSessionWithoutCoreModule()
slang_getEmbeddedStdLib() -> slang_getEmbeddedCoreModule()
hasDeferredStdLib() -> hasDeferredCoreModule()
Following command-line arguments are renamed:
"-load-stdlib" -> "-load-core-module"
"-save-stdlib" -> "-save-core-module"
"-save-stdlib-bin-source" -> "-save-core-module-bin-source"
"-compile-stdlib" -> "-compile-core-module"

* wasm: Add compile target option when creating slang session
Also add a new interface to return spirv code which is binary,
because 'std::string ComponentType::getEntryPointCode' is not
suitable for returning the binary data.
We use a more standard way that wrap the binary data by using
emscripten::val as the return type.
* Add target of metal
