This change fixes an inconsistency between scalar and vector bools, where the formers were stored as i32s in memory (as opposed to i1s in registers) while the latter remained <n x i1>s. This lead to a number of crashes in more complex bool scenarios where scalar and vector element types were expected to match.
The solution is to extend Clang's strategy for scalar bools to vector of bools. Clang relies on three key functions to deal with differences between register and memory type representations which are special-cased for bools and now also for bool vectors. Several HLSL code additions did not properly leverage those functions and this was addressed wherever possible, in some cases removing the need for special cases for bools.
To deal with matrices, a similar concept of register/memory representation was introduced in the matrix lowering code and the lowering passes were updated accordingly.
Implement Length property on constant arrays (FXC regression)
The FXC compiler supports Length property on arrays. This change adds it
to the DXC compiler for backwards compatibility. However, it is marked
obsolete and in HLSL Version 2016 will report a warning. On higher versions
it will result in an error to prompt the developer to either change the code
or to use the -HV flag for backwards compatibility.
Fix HLSLVersion not initialized by default
Adds RewriterTest::RunArrayLength tests which is currently disabled until we have
a way to set HLSLVersion on RewriterTests.
Primarily if not exclusively due to the massive carveouts of the
original LLVM source base as part of the HLSL adaptation, many
variables and functions are left unused. In keeping with the
practice of commenting or ifdef-ing out unused portions of this
code and marking every such exclusion as an HLSL change, this adds
few comments and moves a lot of preprocessor conditionals around to
encompass the portions left unused as a consequence of the earlier
exclusions.
Fixes 450 clang and 442 gcc warnings.
-bump up dll version for fixed version
-show dxcompiler and dxil version number for dxc help message
-emit warnings for dxcompiler validator that container will not be signed
This change is to update correct target data layout for DXIL. Now that we have a scalar type of size less than dwords, we need to correctly print string data layout to determine non-packed structure layout.
This change also fixes alignments issues with ConstantBuffer as it was having different CG path from cbuffer.
In particular, out-of-memory exceptions thrown during string construction in the context of certain move constructors (in this case, and std::pair) would cause the runtime to terminate the process.
The problem is that a noexcept specification was added to some STL move constructors incorrectly, and when the runtime finds such a frame while unwinding, it will invoke std::terminate(). See the comments and static assertions for more details.
Fixes the Realloc implementation in the test memory allocator.
* Implement Length on Input/OutputPatch objects
- use IntTy for object template dimension argument.
- Fix name of TypenameTrue to TypenameFalse, since that's what it means.
- Fix index of vector dimension template argument.
- Fix long bit width/align to 32 for DXILTargetInfo
* Add test
Supporting a custom allocator for dxcompiler.
Adds recovery for exceptions and out-of-memory handling.
Add custom allocator support to linker.
Fix for release-only test failure.
Removes assertion about presence of command-line option registration
Typically this functionality will be triggered via lab automated builds in preparation for a release.
hctbuild supports the required flag already via the -fv switch.
Fix#30: Revert license text in banner comments to original llvm verbage
This commit removes the Microsoft-specific copyright in llvm files
and reverts the copyright wording to the original llvm wording.
We used the following method to find the files to change:
1. Find all files in DirectXShaderCompiler that are also in llvm 3.7
2. For those files that have the Microsoft-specific copyright, revert
it to the original llvm copyright as present in llvm 3.7
3. Revert the copyright in a few files that are not in llvm, but are
mostly copies of files in llvm:
lib\Transforms\Scalar\ScalarReplAggregatesHLSL.cpp
lib\Transforms\Scalar\Reg2MemHLSL.cpp
Leave the Microsoft-specific copyright header in files not present
in stock llvm:
