* 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.

* Add documentation for buffer types
* address comments
* 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"

* Squash redundant move warnings
* Move C interface from slang.h to slang-deprecated.h
spGetBuildTagString remains, because it's useful to have before the
global session exists.
This C API is used quite pervasively in the C++ helpers (for example
slang::UserAttribute. It's not trivial to move these to
slang-deprecated.h as they're entangled with some enums which are
themselves used elsewhere in the compiler.
The fact that these helpers use the C API can be viewed as an
implementation detail for now, and this usage moved to slang-deprecated
in due course.
