We add support for struct and arraytypes in wasm-fuzzer-common. Also, we add addStruct and addArray while generating tests. Other OptRef types like eqref/anyref have been supported. Adding struct and arraytypes in wasm-compile has been placed at the beginning in order to generate them in addSignature.

This patch makes V8 accept the binary format produced by Binaryen after https://github.com/WebAssembly/binaryen/pull/3933 when the --experimental-wasm-gc-experiments flag is present. The explicit inheritance information is not used for anything. Validation is performed only insofar as explicit supertypes must be valid types.

We make an undocumented assumption in {CodeSpaceWriteScope} that a single thread will only work on one module at a time. If this is violated, the thread-local {code_space_write_nesting_level_} would prevent the second module from being switched to writable. This CL adds a second thread local (in debug only) to check that if there is already a {CodeSpaceWriteScope} open that it contains the same {NativeModule} as any nested scope.

This CL limits the amount of address space we reserve for shared WebAssembly memory. Up until now we just reserved either the defined maximum size of the memory or the V8-defined maximum memory size, depending on whether the maximum size is defined or not. This could cause OOMs easily on 32-bit systems due to address space exhaustion. With this CL we limit the amount of address space we reserve for shared WebAssembly memory. 1) We try to reserve at least the initial size; 2) If no maximum size is defined, we reserve 1GB by default; 3) If a maximum size is defined, then we reserve that maximum size but at most 1GB. Note that the handling of shared memory here is different than the handling of not-shared memory because for shared memory it is not possible to grow with realloc.

This CL fixes a long standing issue where reentering TimedHistograms scopes would cause spurious measurements. Only the non-nested scopes yielded correct results. Due to the changed numbers, the V8.Execute histogram is renamed to V8.ExecuteMicroSeconds. Note that this histogram is also guarded behind the --slow-histograms flag due to the additional overhead. Unlike before, it does no longer include time for external callbacks and only measures self time. The following example illustrates the new behaviour: 1. Enter V8: |--+.......+--| self-time: 4 units (reported) 2. Exit V8 (callback): |-+...+-| self-time: 2 units (ignored) 3. Re-enter V8: |---| self-time: 3 units (reported) This would result in 2 histogram entries with 4 time units for the first V8 slice and 3 units for the nested part. Note that the callback time itself is ignored. This CL attempts to clean up how TimedHistograms work: - Histogram: the base class - TimedHistograms: used for time-related histograms that are not nested - NestedTimeHistograms: Extends TimedHistograms and is used for nested histograms This CL changes Histograms to not measure time themselves. Measurements happen in the *HistogramScopes: - BaseTimedHistogramScope: Base functionality - TimedHistogramScope: For non-nested measurements - NestedTimedHistogramScope: For nested measurements - PauseNestedTimedHistogramScope: Ignore time during a given scope. This is used to pause timers during callbacks. Additional changes: - ExternalCallbackScope now contains a PauseNestedTimedHistogramScope and always sets VMState<EXTERNAL> Bug: v8:11946 Change-Id: I45e4b7ff77b5948b605dd50539044cb26222fa21 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3001345Reviewed-by:

For streaming compilation, scripts don't have a source string attached until finalization, but the Script and SharedFunctionInfo objects are already on the heap and may be picked up by heap walks. This happens e.g. in CollectSourcePositionsForAllBytecodeArrays, where we then try to reparse and recompile the SFI. This is invalid, since the source string is not yet set. Avoid this by checking for the empty source string (and leaving a TODO for a nicer future solution).

The number of arguments for the LiftoffCompiler has grown significantly since its initial implementation, and it becomes hard to keep track of all options at the call sites. This CL refactors all optional parameters into a {LiftoffOptions} struct which has a factory-like interface. This will allow us to add more options in the future, e.g. for dynamic tiering.
