For VK_HKR_relaxed_block_layout, a vector inside structs can have
its offset as a multiple of its base element type's alignment.
But the vector's alignment is unaffected, esp. when used for
calculating the alignment of the whole enclosing struct.
Also enables SPIRV-Tools validation on block layouts.
Keeping the original struct type is important for some reflection
workflows.
The validation check for layout is alo included. But we disable
it for now and will re-enable it after fixing all the failures.
Fixes https://github.com/Microsoft/DirectXShaderCompiler/issues/1364
Defaults in switch statments can mask warnings that might
indicate that a new enum value was added and corresponding changes
to a switch statement that relies on that enum are missed. For this
reason, clang reports when switch statements that fully define case
statements for all possible enum values contain default: statements.
However, this is a warning of a potential problem that might arise
from future changes to the code rather than anything that might be
wrong now. Additionally, while unlikely that an enum switch might
be presented with a value that isn't valid for that enum, it isn't
impossible. So rather than respect this warning, we will silence it.
It's not included by default. LLVM wanted it. We don't, so it's
removed. This makes the earlier external cmake change unnecessary.
Ignores 34 clang warnings
clang-spirv-tests uses a lot of external projects that keep
themselves clean with different standards of warnings flags.
This alters the appropriate cmake files to disable flags that
the DXC build enables.
Fixes 72 gcc and 166 clang warnings.
Additionally catch some sign mismatch comparisons in tests
built as part of clang-spirv-tests.
Fixes 2 gcc and 2 clang warnings, but one of them has multiple sources
So it's kind of a lot more.
This CL makes changes to CMake files in order to:
1- disable things that are not supported on non-Windows platforms.
2- make cross-platform compilation possible.
It also brings back LLVM's config.guess (mirrors:
https://github.com/llvm-mirror/llvm/blob/master/cmake/config.guess)
Using SV_RenderTargetArrayIndex (translated into Layer builtin)
and SV_ViewportArrayIndex (translated into ViewportIndex builtin)
in VS and DS output requires the SPV_EXT_shader_viewport_index_layer
extension.
Some compilers require function prototypes and bodies to match with
throw() attributes. This corrects them.
Additionally, it replaces thrown std::exceptions with a string
parameter with runtime_errors, which can take a string on any
system.
Finally, I moved GetPosition in FileIOHelper.cpp to its proper
place with the rest of the AbstractMemoryStream implementation
instead of grouping it with the IDxcBlob implementation
Nonfunctional change. Just inching toward cross platform compatibility
This commit add support for generating OpSpecConstant* instructions
with SpecId decorations. Spec constants are only allowed to be of
scalar boolean/integer/float types. Using spec constant as the array
size does not work at the moment.
This requires us to regenerate the InstBuilder class and also
manually pin the SPIR-V version as 1.0 instead of relying on
spv::Version.
Also refreshed SPIRV-Tools
An implicit object is translated into the first argument to the
method call. If the implicit object is of struct type and its
fields have associated counters, we need to assign its associated
counters accordingly like other normal arguments.
For each such method, we generate associated counters for its
implicit object. At a call site, we assign the associated counters
from the real object to the ones associated with the method implict
object.
Also refreshed SPIRV-Tools
Previously we will return defaultRowMajor as long as the type
is an array. That will hit an assertion failure in translateType()
for arrays of non-matrices.
Also refreshed SPIRV-Tools
We still want to make sure that the generated raw SPIR-V does not
have other validation errors except for allocating variables
containing pointers and returning pointers.
Uses the legalization pass recipe from SPIRV-Tools.
Also change -fcgl to disable both legalization and optimization.
Validation on some tests are turned off because of new image
instruction checking in SPIRV-Tools. Enabling them is a TODO.
When seeing opaque types within structs in function parameter,
function return, and variable definition, invoke SPIRV-Tools
legalization passes.
Also refreshed external projects
With this change, targets in the subdirectory will not be included
in the ALL target of the parent directory by default, and will be
excluded from IDE project files.
* Added effcee and its dependencies (re2) to the project.
* Introduced FileTest that uses effcee to perform checks.
* Added a sample test (check-entrypoint.hlsl)
* Refactored code so WholeFileTest and FileTest can reuse code.
This change enables CodeGenSPIRV test flow.
New tests can be added by simply adding the test file to
`tools/clang/test/CodeGenSPIRV/` directory and running:
```cpp
TEST_F(WholeFileTest, NewTest) {
EXPECT_TRUE(runWholeFileTest("new-test-name"));
}
```
The input file with the format described in `WholeFileCheck.h` is read in;
the HLSL portion is passed to the compiler with SPIR-V codegen enabled.
The resulting SPIR-V binary is disassembled and compared to the expected
result in the input file.
GoogleTest will be used for unit testing and codegen testing for
SPIR-V.
* Added SPIRV_BUILD_TESTS option in CMake to control building
of SPIR-V tests.
* Added "-spirvtest" into hctbuild to enable it.
* Added "spirv" and "spirv_only" targets for hcttest.
Running `hcttest spirv` will run ALL tests including SPIRV tests.
Running `hcttest spirv_only` will ONLY run SPIRV tests.
The default behavior of hctbuild and hcttest is not changed.
