Extends the pass for removing unused instructions so that it can
remove global declarations (such as types and variables) that are only
used by decorations with which they are intimately connected, such as
descriptor set and binding decorations.
* Allow OpExtInst for DebugInfo between secion 9 and 10
Fixes#3086
* Handle spirv-opt errors on DebugInfo Ext
* Add IR Loader test
* Fix ir loader bug
* Handle DebugFunction/DebugTypeMember forward reference
* Add test cases (forward reference to function)
* Support old DebugInfo extension
* Validate local debug info out of function
Added exports for libraries. External libraries that themselves use
libraries require all dependencies have exports, so not having exports can
cause major problems when used within other projects.
Install paths for exports are now placed in the proper directories expected
by Windows and *nix systems. Config files are generated as well, which
should work with CMake's find_package() function once installed.
* Remove Impl struct in Reducer; we can re-add it later (in a cleaner fashion) if we need to.
* Add cleanup passes in Reducer; needed so that removal of constants can be disabled during the main passes, and then enabled during cleanup passes, otherwise some main passes can perform worse due to lack of available constants.
* Delete passes: remove op name, remove relaxed precision. And delete associated tests.
* Add more tests for remove unreferenced instructions.
* Always return and write the output file, even if there was a reduction failure.
* Only exit with 0 if the reduction completed or we hit the reduction step limit.
Adds a reduction pass that removes OpDecorate and OpMemberDecorate
instructions that annotate instructions and members with
RelaxedPrecision. As well as being useful in its own right, removing
such references allows other passes to remove further instructions.
WebGPU requires certain variables to be initialized, whereas there are
known issues with using initializers in Vulkan. This PR is the first
of three implementing a pass to decompose initialized variables into
a variable declaration followed by a store. This has been broken up
into multiple PRs, because there 3 distinct cases that need to be
handled, which require separate implementations.
This first PR implements the basic infrastructure that is needed, and
handling of Function storage class variables. Private and Output will
be handled in future PRs.
This is part of resolving #2388
* Fix#2320. `conditional_branch_to_simple_conditional_branch` reduction pass changes conditional branches so both targets point to the same block id (creating a "simple" conditional branch).
* Fix#2501. `simple_conditional_branch_to_branch` reduction pass changes "simple" conditional branches to branches.
* Fix#2503. `conditional_branch_to_simple_conditional_branch` proper handling of back-edges.
* Fix#2478. The fix is to just not try to simplify such loops.
* Also added `BasicBlock::MergeBlockId()` and `BasicBlock::ContinueBlockId()`.
* Some minor changes to `structured_loop_to_selection_reduction_opportunity.cpp`.
* Added test.
Fix#2475. Fix#2476.
* Improve reducer algorithm: shrink granularity, remove an early return, no lazy initialization, notify pass if binary is interesting, add comments.
* Add fail-on-validation-error option to fail a reduction if an invalid state is reached; useful for tests.
* Set fail-on-validation-error in tests.
* Improve some documentation comments.
* Add Reducer::AddDefaultReductionPasses so tests (and other library consumers) can add the default reduction passes.
* Add CLIMessageConsumer in test_reduce so we can see messages for tricky tests.
* Remove test RemoveUnreferencedInstructionReductionPassTest_ApplyReduction because it was indirectly testing the reduction algorithm, not the RemoveUnreferencedInstruction pass.
* Tweak tests where needed.
Fix#2396
* Check that initial state is valid. Add kInitialStateInvalid.
* Fix RemoveOpnameAndRemoveUnreferenced test; turns out the original shader is invalid, but we never notice because we don't check this and the reduced shader is valid; fix original shader. Assert reduction status is kComplete.
* Always check return value from `Reducer::Run`.
* Change Reducer::Run to *not* immediately copy the input binary.
* Fixes#2358. Added to the reducer the ability to remove a function that is not directly called. Factored out some code from the optimizer to help with this.
Fixes#2120
Enhanced the reducer so that it can merge blocks together, leveraging the functionality extracted from the block_merge pass in the optimizer.
* Add OperandToUndefReductionPass.
Fixes#2115.
Also added some tests that are similar to those in OperandToConstantReductionPassTest.
In addition, refactor FindOrCreateGlobalUndef into reduction_util.cpp. Fixes#2184.
Removed many documentation comments that were identical or very similar to the overridden function's documentation comment.
* Run validator during reduction.
* Added functionality to validate modules after each reduction step, and some tests to check this is working. Also fixed an issue where reduction passes were not guaranteed to be executed at their minimum granularities.
Add a spirv-reduce pass which removes OpName and OpMemberName instructions.
This is useful to enable other reduction passes, e.g. RemoveUnreferencedInstruction may not be able to remove an instruction creating an id whose only usage is an OpName for this id.
* Added a reduction pass to replace ids with ids of the same type that dominate them.
* Introduce helper method for querying whether an operand type is an input id.
