Benedikt Meurer authored
This avoids the call to the StringCharCodeAt builtin from within TurboFan optimized code and instead emits a loop that does the character load. This (together with previously reverted CL to the JSCallReducer) almost completely recovers the performance regression caused when we shipped TurboFan. Without untrusted code mitigations the benchmark goes from 580ms to roughly 490ms, and with the patch to the JSCallReducer the time goes down to 280ms, which is very close to what we had with Crankshaft. This also renames the LoadFromString helper method in the EffectControlLinearizer to LoadFromSeqString to make it clear what it does.

It took me a while to understand that the {index} is actually a signature index. This CL changes the name to {sig_index} to make this more clear. Drive-by: Fix a CHECK to check the canonical signature index instead of the original index. This ensures that there is a canonical signature index in the signature map. Drive-by^2: Un-templatize a method.

This works around a bug in the libc++ implementation of bitset (https://bugs.llvm.org/show_bug.cgi?id=35438) resulting in high bits outside the bitset leaking through, breaking the ordering invariant of PersistentMap::iterator.

Dan Elphick authored
This removes the Javascript version of Array.of in js/array.js and adds a CodeStubAssembler version in src/builtins/builtins-array-gen.cc. Mostly this change is for code-health reasons but it also gives performance improvements for nearly all cases with the exception of "transplanted" arrays. E.g. function ArrayLike {} ArrayLike.of = Array.of ArrayLike.of(...) is now slower in the perf tests. Most of this change can be attributed to using CallRuntime(kSetProperty,...) to set the length. The JS version can do better due to inline caches trained on the same datatype for 1000s of iterations, but this kind of workload is unlikely.

This is a further step to separate the implementation of the JavaScript API from the internals of the WASM implementation. Now, wasm-js.cc only needs to interact with the WASM engine and is (almost) independent of module-decoder.h and module-compiler.h. Also, move SyncCompileAndInstantiate() into wasm-module-runner.cc.
