New Rules:
outer type may be: [ptr to][1 dim array of]( UDT struct | scalar )
inner type (UDT struct member) may be: [N dim array of]( UDT struct | scalar )
scalar type may be: ( float(16|32|64) | int(16|32|64) )
- Disallow pointers to pointers, and pointers in structs
- Disallow multi-dim arrays at top-level, but allow within struct
* Erase dead region
* Pass dependencies
* Simpler heuristic, only checking that Begin dominates End and End post dominates Begin
* Small cleanups. No longer iterating whole block to find PHIs
* A few optimizations. Fixed infinite loops caused by self-loops
Fixes problems like:
- extra AllocateRayQuery calls, or improper location (for lifetime)
- proper array support
- static global RayQuery
This RayQuery allocation changes:
- Add a constructor to RayQuery
- Set init sequence to use constructor in InitializeInitSequenceForHLSL, just for RayQuery
- For array: modify EmitCXXAggrConstructorCall to
- loop over index instead of pointer to allow SROA of RayQuery struct
- mark the loop as HlslForceUnroll
- Add hidden flag for HL intrinsics to allow internal intrinsic not produced
by HLSL directly - mangle name so it can't be matched during parse.
- Add hidden HL AllocateRayQuery intrinsic
- Translate constructor call on ptr to HL AllocateRayQuery intrinsic call producing handle i32 during FinishCodeGen
- Translate RayQuery ptr to load i32 handle value for intrinsic methods during SROA_HLSL
- Flatten RayDesc for TraceRayInline
(otherwise /Od fails validation since RayDesc type may still be present)
- No longer skip RayQuery for SROA_HLSL
- Update lowering for AllocateRayQuery, i32 handle, and flattened RayDesc
- Remove ReadNone attribute from AllocateRayQuery to prevent incorrect CSE optimizations
- Manually cleanup unused RayQuery allocations
* Adding test fixes and more support for SM6.5 WaveMultiPrefix functions
1) Ensure wave lane-id’s are sorted when accumulating result
2) Fix made for HLSL in ShaderOpArithTable.xml to ensure the input aligns with what is being tested
3) Added support for the “UBit” version for all of these tests.
Two test options, -Qstrip_reflect_from_dxil and -Qkeep_reflect_in_dxil
for making tests work with reflection removed, since many tests are relying
on main module disassembly-reassembly between test phases and reflection
metadata will no longer be present there. The strip option is for the
few cases where tests don't want the reflection kept in DXIL by default.
Validator no longer requires function annotations for no reason.
Fix places where remove global hook was not being called when functions
were removed manually from the list.
StripReflection now deletes function annotations, unless targeting lib or
old validator that required them. Preserve global constructor list and
add annotation for 1.4 validator. The global hook fixes were required
here, otherwise annotations would refer to dead functions during linking.
Struct annotations may not be removed in library case when they still need
translation to legacy types.
Allow missing struct annotation when not necessary to upgrade the layout.
Preserve usage in reflection by upgrading the module, emitting metadata,
cloning for reflection, then restoring validator version and re-emit
metadata.
Fix size for 16-bit type for usage and reflected size.
Make various batch reflection tests require validator 1.5, since these
tests rely on module disassembly->assembly, which will not preserve extra
usage metadata for reflection in 1.4.
Include reflection part in IDxcAssembler, but don't strip from module,
since there are no options to prevent this from breaking a lot of tests.
Don't strip reflection from offline lib target.
- Align coord dimensions with Sample for future flexibility and alignment
- Fix ddx and ddy arguments to support the correct number of dimensions
- Rewrite lowering, using SamplerHelper
- Clean up SampleHelper a bit, adding additional asserts/checks
- Set components to zero for default offset, not undef
- Compute mesh payload size before final object serialization
- During CodeGen for MS based on payload parameter
- During CollecShaderFlagsForModule for AS based on DispatchMesh call
- Store payload sizes in corresponding funtion properties, serializing
these properly for HL and Dxil Modules
- Use payload sizes from function props for PSV0 data during serialization
- Validate measured and declared payload sizes, don't just fill in
properties during validation
- Fix Wave/Quad allowed shader stages, enabling Quad* with CS-like models
- rename payloadByteSize members to payloadSizeInBytes
- Add GetMinShaderModelAndMask overload taking CallInst for additional
detail required to produce correct SM mask for Barrier operations
- Update the HLSL syntax from FeedbackTexture2DMinLod to FeedbackTexture2D<SAMPLER_FEEDBACK_MIN_MIP>
- Update DXIL to only have two UAV types for FeedbackTexture2D[Array] and use an extra metadata field to distinguish between the sampler feedback type.
The tests were manually added to ShaderOpArithTable.xml in PR #1867,
but ShaderOpArithTable.xml should be generated by hctdb_test.py script.
No actual changes to the test data, just the order of the tests is different
because of rearranging done by the script XML processing.
Added a check for shader model 6.5 so the tests will be skipped on lower
shader models.
- base of struct should always be aligned - or internal bug
- offset for array member must always be aligned - (new) validation error
- alloc and verify struct layouts even when not array field
- out of bound check would have missed OOB on last array element
Added generating of new version for each DX Compiler build.
There are 3 kinds of version:
1. **Official build**
Built by using `hctbuild -official`. The version is based on the current DXIL version, latest official release and a number of commits since then. The format is `dxil_major.dxil_minor.release_no.commit_count`. For example a current official version would be something like `1.5.1905.42`. The latest release information is read from `utils\version\latest-release.json`. The `1905` corresponds to `dxil-2019-05-16` release branch and `42` is the number of commits since that release branch was created. For master branch the `commit_count` will be incremented by 10000 to distinguish it from stabilized official release branch builds. So the current official version of master would be someting like `1.5.1905.10042`.
2. **Dev build**
Build by using `hctbuild` with no other version-related option. The format is `dxil_major.dxil_minor.0.commit_count` where commit_count is the number of total commits since the beginning of the project.
3. **Fixed version build**
Build by using `hctbuild -fv`. Enables overriding of the version information. The fixed version is read from `utils\version\version.inc`. Location of the version file can be overriden by `-fvloc` option on `hctbuild`.
In addition to the numbered version the product version string on the binaries will also include branch name and last commit sha - `"1.5.1905.10042 (master, 47e31c8a)"`. This product version string is included in `dxc -?` output.
Adds support for templatized RWRawByteBuffer.Store<T>. To avoid SROA making us lose the original layout of any struct arguments, a new pass runs before SROA and breaks down such cases into per-element stores. So better be careful with the likes of buf.Store(0, (int[65536])0);...
-Qstrip_reflect would reserialize the root signature, leading to
validation failure #2162. Fixed by moving root sig to writer to clear
from module and prevent re-serialization to metadata.
Fixed -Qstrip_debug with -Zi and no output location still embeding
debug module.
- New -Qembed_debug is required to embed PDB in shader container
- -Zi used without -Qembed_debug will not embed debug info anymore,
and will issue a warning from CompileWithDebug().
- When compiling with Compile() and -Zi, -Qembed_debug is assumed
for compatibility reasons (lots of breaks without it)
- In dxc and CompileWithDebug() -Fd implies -Qstrip_debug
- Debug name is based on -Fd, unless path ends with '\', meaning you
want auto-naming and file written under the specified directory
- Debug name always embedded when debug info used, or -Fd used
- -Fd without -Zi just embeds debug name for CompileWithDebug(),
still error with dxc, since it can't write to your file.
- If not embedding debug info, it doesn't get written to the container,
only to be stripped out again.
- Fix padding for alignment in DebugName part.
- Default to DebugNameForBinary instead of DebugNameForSource if no
DebugInfo enabled
- Also fixed missing dependency on table gen options from libclang
