spirv-reduce: Remove redundant r-value references (#4232) 2021-04-09 13:55:51 +01:00

reduce: improve remove unref instr pass (#2945)
* 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.

Improve reducer algorithm and other changes (#2472)
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.

Add some val options to reduce (#2401)
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.

86d0d9be25 Refactored reducer so that the 'finding' functionality of a reduction pass are separated from the generic functionality for tracking progress of a pass. With this change, we now have a ReductionOpportunityFinder abstract class, with many subclasses for each type of reduction, and just one ReductionPass class, which has an associated finder. (#2321)
Sounds good.
