This reverts 0944553e. This is a short-term fix for NodeJS regression caused by Scavenger not collecting weak handles that are marked as independent.

Tobias Tebbi authored
This implements a reasonable overload resolution strategy for operators: An overload is selected if it is strictly better than all alternatives. This means that it has to be strictly better in at least one parameter, and better or equally good in all others. When comparing a pair of corresponding parameters of two overloads... ... they are considered equally good if: - They are equal. - Both require some implicit conversion. ... one is considered better if: - It is a strict subtype of the other. - It doesn't require an implicit conversion, while the other does. If no overload is strictly better than all alternatives, this results in a compile error.

This moves the generation of the WasmCode structure into the PipelineWasmCompilationJob, removing WasmCodeDesc in the process. WasmCodeDesc was a structure that was not understood by other parts of the compiler, including the disassembler. Using WasmCode right away enables printing code comments for turbolizer.

Michael Starzinger authored
This makes stack checks in WasmCode independent of the underlying Isolate by loading the limit address from the WasmInstanceObject instead of embedding it into the instruction stream. It hence removes the last use of the Isolate field from WasmGraphBuilder. Additionally this introduces the notion of a "runtime stub" which represents stub code global to the NativeModule that can be directly called from each WasmCode in the same module. These stubs can act as trampolines via which Isolate-independent WasmCode can enter other V8 builtins or runtime functions that remain Isolate-dependent. They will eventually replace the current "trampoline" in a NativeModule.

This CL implements a generic baseline version and 3 fastpaths, for various elements kinds, of Array.p.sort in Torque. Details can be found in the Design Doc: https://goo.gl/Ge321G. Performance impact on micro benchmarks depends on the element kind and whether the user provides a comparison function. For HoleySmi/HoleyElement we have a speedup between 1.5-1.8 across the board. For Dictionary we are slower in all micro benchmarks (0.7). For PackedSmi it depends on the call site and whether or not a comparison function is used.

Adds a new flag v8_deprecate_get_isolate that marks HeapObject::GetIsolate/GetHeap, Handle<T>(T*) and handle<T>(T*) as [[deprecated]]. Deprecation warnings are not converted to errors so an entire build can be completed to collect all the warnings. Also adds a new script tools/collect_deprecation_stats.sh which runs the build (assuming the flag is set) and collects the number of uses of deprecated functions. E.g. at the time of upload, we get: Total deprecated calls: 2265 515 GetHeap 842 GetIsolate 210 handle 698 Handle Bug: v8:7786 Change-Id: I7043c597fa90bc77759a357ef3c2a5fefe933491 Reviewed-on: https://chromium-review.googlesource.com/1082478Reviewed-by: -

This CL introduces new method: Runtime.installBinding. This method installs binding function by given name on global object on each inspected context including any context created later. Binding function takes exactly one string argument. Each time when binding function is called, Runtime.bindingCalled notification is triggered and includes passed payload. Binding function survives page reload and reinstalled right after console object is setup. So installed binding can be used inside script added by Page.addScriptToEvaluateOnNewDocument so client may do something like: Runtime.installBinding({name: 'send'}); Page.addScriptToEvaluateOnNewDocument({source: 'console.debug = send'}); .. navigate page .. In microbenchmark this function is ~4.6 times faster then console.debug.
