GN does not allow multiple build files to declare the same executables,
so for SwiftShader to be able to use its own internal copy of SPIRV-
Tools libraries it needs to exclude the executable targets.
This is achieved by checking if the current path is //third-party/
SPIRV-Tools/.
Bug: b/158002593
Clang added -Wunqualified-std-cast-call in
https://reviews.llvm.org/D119670, which warns on unqualified std::move
and std::forward calls. This change qualifies these calls to allow the
project to build on HEAD Clang -Werror.
If the body of the module does not have any ids change, compact ids will
not change the id bound. This can cause problems because the id bound
could be much higher than the largest id in that is used. It should be
reset any time it is not the larger id used + 1.
Fixes#4604
When folding a vector shuffle feeding a vector shuffle, we do not
propagate an 0xFFFFFFFF, which has a special meaning, correctly. We
adjust the value making it lose it meaning as an undefined value.
Fixes#4581
CCP does not want to fold an instruction unless it folds to a constant.
There is an asser to check for this. The question if a spec constant
counts as a constant. The constant folder considers a spec constant a
constand, but CCP does not. I've fixed the assert in CCP to match what
the folder does. It should not require any new changes to CCP.
* Fixed Bazel Windows build
Before this commit, the bazel build setup would not work on windows.
This is due to the fact, that genrule tries to use bash, which fails.
One fix would be to use bazel-skylib's run_binary.
This however does not work (easily) since genrules is more complex.
To (temporarily) fix the windows build, I added the `cmd_bat` property to every genrule.
This seems more like a hack, because it basically repeat commands,
but for now it at least builds on windows.
* Removed BAZEL_SH from bazel presubmit build script
Thanks to @s-perron for pointing out, that the presubmit script uses the msys64 bash shell for the bazel build.
Since adding the `cmd_bat` argument removes the dependency on bash, this is no longer needed.
Swift shader needs a way to inline all functions, even those marked as
DontInline. See https://github.com/KhronosGroup/SPIRV-Tools/pull/4471.
This implements the suggestion I made in the PR. We add a pass that
will remove the DontInline function control, so that the inlining passes
will inline them.
SwiftShader will still have to modify their code to add this pass before
the other passes are run.
The function `BuildInvalideAnalyses` will be rebuilt for every analysis that
has been requested, but it is not necessary. It also can cause problems
because if the CFG needs to be rebuilt, so do the dominator trees.
This change will make the functionality match the description of the
function.
* Use bazel 5 for Linux bazel builds.
* Download bazel 5.0.0 for macos and windows bazel builds.
* Modify the readme to mention bazel 5.0.0 as the version to use.
* Optimize DefUseManager allocations
Saves around 30-35% of compilation time.
For inst->use_ids, use a pool linked list instead of allocating vectors for every instruction. For inst->uses, use a "PooledLinkedList"' -- a linked list that has shared storage for all nodes. Neither re-use nodes, instead we do a bulk compaction operation when too much memory is being wasted (tuneable).
Includes separate PooledLinkedList templated datastructure, a very special case construct, but split out to make the code a little easier to understand.
Incrementally compute the hash instead of collecting words
Avoids allocating temporary space in a std::vector and std::u32string, and making three passes over all the hashed data.
Switch to using std::vector to prevent processing duplicates instead of std::unordered_set: avoids an allocation/deletion every call to ComputeHashValue, and ends up faster due to much better cache behaviour and smaller constant-factor when searching the (generally very small) list.
In my test case, made Type::HashValue go from 7.5% of compilation time to .5%
In newer versions of protobuf the Status building code has been made
internal, so that embedders cannot build their own instances like is
being done here.
Changing this code to just use the .ok() method on the status object,
since if the status is OK or not is what is actually being tested.
This will make it easier in the future to update external/protobuf.
The copyright check has hardcoded the years that can appear in the
copyright check. This means is has to be constantly updated as new
years or range of years are needed.
We try to avoid this, at least for a while. We allow years up to 2027.
The ranges for the years allow any combination of from 2014 to 2027.
* Update test for parsing memory access masks
Needed to support SPV_INTEL_memory_access_aliasing extension
There is a negative test that checks unused mask bits.
Some of those bits are now sued by the new Intel extension.
* Update deps for new SPIRV-Headers
Previously, array sizes were presumed to be OpConstant, which is not
necessarily true. This change ensures OpSpecConstant array sizes as
matched exactly, instead of taken as OpConstant and matched by value.
* Reimplement LCS used by spirv-diff
Two improvements are made to the LCS algorithm:
- The LCS algorithm is reimplemented to use a std::stack instead of
being recursive. This prevents stack overflow in the LCSTest.Large
test.
- The LCS algorithm uses an NxM table. Previously, entries of this
table were {size_t, bool, bool}, which is now packed in 32 bits. The
first entry can assume a maximum value of min(N, M), which
realistically for SPIR-V diff will not be larger than 1 billion
instructions. This reduces memory usage of LCS by 75%.
This partially reverts 845f3efb8a and
enables LCS tests.
* Stabilize the output of spirv-diff
std::map is used instead of std::unordered_map to ensure the output of
spirv-diff is identical everywhere.
This partially reverts 845f3efb8a and
enables spirv-diff tests.
Scalar replacement generates a null when there value for a member will
not be used. The null is used to make sure things are
deterministic in case there is an error.
However, some type cannot be null, so we will change that to use undef.
To keep the code simpler we will always use the undef.
Fixes#3996
spirv-diff is a new tool that produces diff-style output comparing two
SPIR-V modules. The instructions between the src and dst modules are
matched as best as the tool can, and output is produced (in src
id-space) that shows which instructions are removed in src, added in dst
or modified between them. The order of instructions are not retained.
Matching instructions between two SPIR-V modules is not trivial, and
thus a number of heuristics are applied in this tool. In particular,
without debug information, it's hard to match functions as they can be
reordered. As such, this tool is primarily useful to produce the diff
of two SPIR-V modules derived from the same source.
This tool can be useful in a number of scenarios:
- Compare the SPIR-V before and after modifying a shader
- Compare the SPIR-V produced from a shader before and after compiler
codegen changes.
- Compare the SPIR-V produced from a shader before and after some
transformation or optimization.
- Compare the SPIR-V produced from a shader with different compilers.
The handling of the RayQueryKHR type is not complete in the type
manager. The tests were not picking this up. I've added a test to make
sure that the `GenerateAllTypes` function actually does generate all of
the types. Once it is added there other tests should pick up on the
other parts that were missing.
