The test runner automatically infers certain options from the build product if it was generated with GN. This CL makes the code for inferring the options more generic and makes sure that: 1) boolean options can't be set on builds where they don't make sense (e.g. can't pass --asan in a non-asan build) 2) string options are equal to the derived option from the build (e.g. can't test arch x64 when build is x86) Bug: v8:5533 Change-Id: I4badf3a17a2fc23ddb9d129602aa15f12665821f Reviewed-on: https://chromium-review.googlesource.com/552542Reviewed-by: Jakob Kummerow <jkummerow@chromium.org> Commit-Queue: Michael Achenbach <machenbach@chromium.org> Cr-Commit-Position: refs/heads/master@{#46385}

Use these names to actually name the reported locals, instead of using the default names "param#<d>" and "local#<d>". These names are only used as fallbacks for locals which were not assigned a name.

The jsapi-harness test runs the JS-API spec tests of WebAssembly, which get fetched from github when 'gclient sync' is executed. Without 'gclient sync' the harness may executed a version of the tests which is older than required by the harness. In this CL I add a suggestion to the test to run 'gclient sync' which is shown when the test is failing.

Replace the second level visitation with a much simpler logic that just separately dispatches the special cases. All other cases can use a dispatch that just evacuates an object based on size. This is similar to the logic used in the mark-compact collector. The goal is to align behaviors as much as possible, highlighting and fixing performance issues in the different behaviors. This CL is mechanical as possible. A followup will clean up the naming scheme and dispatching.

The `FAST_` prefix doesn’t make much sense — they’re all just different cases with their own optimizations. Packedness being implicit (e.g. `FAST_ELEMENTS` vs. `FAST_HOLEY_ELEMENTS`) is not ideal, either. This patch renames the FAST elements kinds as follows: - e.g. FAST_ELEMENTS => PACKED_ELEMENTS - e.g. FAST_HOLEY_ELEMENTS => HOLEY_ELEMENTS The following exceptions are left intact, for lack of a better name: - FAST_SLOPPY_ARGUMENTS_ELEMENTS - SLOW_SLOPPY_ARGUMENTS_ELEMENTS - FAST_STRING_WRAPPER_ELEMENTS - SLOW_STRING_WRAPPER_ELEMENTS This makes it easier to reason about elements kinds, and less confusing to explain how they’re used.

Catch prediction for optimized frames had two issues: Inlined frames were iterated from caller-to-callee (which could result in incorrect predictions if one frame predicted CAUGHT and another predicted PROMISE). When encountering a builtin frame, we'd unconditionally return its prediction (which is wrong if it predicted UNCAUGHT and another inlined frame predicted either CAUGHT or PROMISE). This CL fixes both issues and refactors the function to reduce nesting.

V8's catch prediction mechanism tries to predict whether a thrown exception will be caught, just by looking at the current call stack. At the time when catch prediction was first introduced, only a few builtins (mostly related to Promise and Generator) could end up being fed into the catch prediction mechanism. This is no longer the case now that builtins are used in new ways, e.g. Array.p.forEach's continuation builtins. This CL removes the need to explicitly mark all builtins visible to the StackFrameIterator as CAUGHT/UNCAUGHT/PROMISE, and instead defaults to treating unmarked builtins as UNCAUGHT.

Building on Windows with gyp fails depending on the result from sharding the src/v8.gyp:v8_base target. If two source files with the same name are in the same shard, their output object file path would conflict with one another. One example of this conflict is v8_base's runtime/runtime.cc and the V8 inspector's protocol/Runtime.cpp that is generated at build time, for which the files runtime.obj and Runtime.obj would be created, but MSVS overwrites one of them with the other. Dividing the .obj output path by the original source's extension prevents this overwrite.

This reverts commit 1520a851. Reason for revert: This CL does not do what it should. All tasks which access the isolate have to be cancelable to guarantee that the isolate still exists when the task is executed. Foreground compilation tasks access the isolate, so they cannot be just normal tasks. Original change's description: > [wasm] Run foreground compilation tasks as normal tasks > > This CL makes foreground compilation tasks normal (i.e. not cancelable) > again, because otherwise a deadlock can happen. I think the reason why > the foreground tasks were cancelable was to make sure that all tasks > either finish correctly or get canceled. However, since the isolate can > only shut down on the main thread, this means that the foreground task > should have already finished when the isolate shuts down, or it should > not have started at all. I reordered the deletion of the AsyncCompileJob > though to make sure that an AsyncCompileJob is removed from > CompilationManager before its promise is resolved. > > Here is the deadlock: The JS code which is executed after a promise is > resolved is executed within the task which resolves the promise. In case > of async compilation this means that some JS code is executed within a > CompileTask. In JS, the shutdown of the isolate can be triggered. During > the shutdown of the isolate, the CancelableTaskManager waits for all > registered cancelable tasks to complete, including the CompileTask of > async compilation.

It can happen that coverage infos for a function containing IncBlockCounter bytecodes can be deleted (e.g. by switching to best-effort coverage). Handle this case correctly in the IncBlockCounter runtime function.

This reverts commit 0d2ed6c3. The CL introduced perf regressions: crbug.com/735649. We are going to reland the CL in an isolated V8 roll to ensure that perf regressions are attributed correctly.

This CL adds a new function {InitializeCompilationUnit} to initialize a single compilation unit and not just all compilation units at once. This is necessary for streaming compilation eventually. This also required some refactoring on how the working queue for compilation units works. Previously the synchronization was done with an atomic counter, now it is done with a lock. Note that the code to finish compilation of a module still only works if the working queue gets only empty when all work is done. I plan to change this in a different CL. Since the code would not be tested without streaming compilation, I added an experimental flag and a test to test the new code.

This way, each lazy function needs to handle only the data relevant to itself. This reduced data handling overheads. Other changes: 1) Don't deserialize the data; once it's on the heap, it can stay there. Lazy function compilation is only done in the main thread. 2) Separate ProducedPreParsedScopeData and ConsumedPreParsedScopeData. It's clearer, because: - The data looks fundamentally different when we're producing it and when we're consuming it. - Cleanly separates the operations we can do in the "producing phase" and in the "consuming phase".
