This change is to support preserve denorm operations. We do this by creating dxc options and propagate them all the way to dxil metadata so that drivers can see how it should handle floats.
Currently we support three modes: any(default), preserve, and ftz
Denorm option will be of per function flag. We store this information at function annotation metadata. This means that for DXIL 1.2 we have a new structure for function annotation. The change in structure is documented on DXIL.rst
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
* Add documentation with source-level debugging with HLSL and DXIL.
* Fix trailing underscore in generate .rst documentation.
* Add container support for debug name part.
* Bump validator version to 1.1.
* Implement debug stripping in dxc, including /Fd dir-named behavior.
* Implement IDxcCompiler2 and CompileWithDebug.
* [spirv] Add libclangSPIRV and skeleton FrontendAction for SPIR-V
* [spirv] Add -spirv into dxc for invoking EmitSPIRVAction
* [spirv] Build SPIR-V codegen conditionally
Added ENABLE_SPIRV_CODEGEN in CMake config to control the
building of SPIR-V component and wrap up SPIR-V code using it.
Also add -spirv to hctbuild to turn it on.
1. Remove debug info when strip function parameter from entry function.
2. Set OptLevel to 0 for -Od.
3. If optimization is disabled, always load ReturnValue.
This commit adds a standalone class for expanding macros and uses it
to for root signature and semantic define processing. Previously,
we were using the raw macro value instead of the expanded value
so something like:
#define MYRS "DescriptorTable(SRV(t0))"
#define RS MYRS
would fail to compile the root signature with an entry point of
RS because it would get a root signature value of MYRS instead
of the expanded value. Similarly, for semantic defines we were
saving the non-expanded value into the bitcode.
This commit also adds a new flag that is used to specify that
the root signature should be read from a #define. So compiling
with `-rootsig-define RS` will read the root signature from
a `#define RS ...` in the source. The -roosig-define flag
takes precedence over a root signature annotation in the souce.
* Dxc fix verifyrootsignature option
- distinguish stream type (stdout, stderr) when printing to console
- verifyrootsignature option returns correct errorlevel depending on its result
- adding more test cases to hcttest for verifyrootsignature option
- enable verifyrootsignature option when dxil.dll not present
* Fixes from review
- Change parameters for writing to consoles from File* to DWORD
- Change comment when dxil.dll does not exist
* Clean up dxc options:
setrootsignature, setprivate :
Allow replacing existing rootsignature or private data and make a new container with new parts
(e.g dxc /dumpbin private.dxil /setprivate private.data /Fo private.new.dxil)
extractrootsignature:
Make it back compatible with fxc by returning dxil container with RTS0 part only and having the user to provide /Fo option.
Other Options:
For unimplemented options that was from fxc, ignore those options and proceed given operation.
For unimplemented options that was not from fxc, remove them for now.
Add more test cases for dxc command line operations.
Fix ISenseOption flag to have valid HLSL version check for dxc (disable 2015)
* Fix Preprocess option for dxc
Fix hcttestcmd for testing invalid rootsignature
- Update command line options of dxc
(Qstrip_debug, Qstrip_priv, Qstrip_rootsignature, setrootsignature, getprivate, setprivate)
- Add IDxcContainerBuilder API and its implementation
- Resolve lifetime of dxil.dll on dxcompiler.dll to guarantee access of memory generated from dxil.dll
