deopt-unlinked.js: bytecode flushing destroys the information that %GetDeoptCount relies on, so turn that off for this test. cleanupsome-after-unregister.js: the function-local object {o} is assumed to be alive throughout the function, so make sure its live range (from the optimizing compiler's view) extends that far. Drive-by cleanup: drop some unnecessary casting boilerplate from Genesis::InitializeGlobal_harmony_intl_date_format_range().

This adds a counter for the time it takes per single code GC. It is sampled in all isolates whenever a GC finishes, and during regular JavaScript GC to also get samples for GCs that never finish (which we would need to fix).

We currently have the problem that we trigger too many code GCs since {new_potentially_dead_code_size_} is never reset to zero. This CL adds a counter which tells us how many GCs we ran per native module. This counter is sampled on each code GC. It will give us a good understanding of the amount of GC work we are executing in the wild. The number should stay in the single-digits generally.

Port 8e7945a6 Original Commit Message: Port 381a7f9e Original Commit Message: On Arm/64 the last return address is stored in a link register instead of being pushed to the top-of-stack like on x64/ia32. Extend the support in the tick sampler to check for samples in a frameless bytecode handler with support for checking the link register if it exists instead of top-of-stack. In addition, make the x64/ia32 check more robust by ensuring we only apply the change if the pc is a bytecode handler and the top frame isn't a bytecode handler (stub) frame.

When TurboFan doesn't know anything about the receiver, it will generally insert a call via CallFunctionTemplate builtin, which does all the necessary checks. For this we don't need to be able to deoptimize, so there's no need to have the speculation bit available. This restores the performance in the case of calling API methods and accessors via `Function#call()`, i.e. like in this example: ```js const hasAttribute = Element.prototype.hasAttribute; // ... hasAttribute.call(element, "bar"); ``` Bug: v8:8820 Change-Id: Ic30719d7db75141023efc11d76180b001f871d28 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1615248 Auto-Submit: Benedikt Meurer <bmeurer@chromium.org> Commit-Queue: Georg Neis <neis@chromium.org> Reviewed-by:

This CL extends Error.stack to include frames of functions declared with the C++ FunctionTemplate API. For example, "print" in d8. Two changes are necessary: - HandleApiCall and friends need to go through an BUILTIN_EXIT frame instead of an EXIT frame. The existing stack-trace machinery will then pick up FunctionTemplate frames without additional changes. - Turbofan doesn't go through HandleApiCall, but instead uses an ASM builtin to enter FunctionTemplate functions. A "marker" frame state is needed to include these frames in the stack trace. Note: This CL only includes these frames in Error.stack, but not (yet) in the stack-trace API (v8.h).

The language server and unit tests pass in an empty output directory to signal that no C++ files should be generated. As these generation steps include some validations, they should also be included in language server and unit test compilation runs. This CL introduces a "dry run" flag on the ImplementationVisitor. Additionaly, the implementation visitor wraps the file writing functionality. In case of a dry-run, file writing becomes a no-op.

Building Chromium Win64 ThinLTO is faulting, with a link error on a missing symbol. The fix is to add a __declspec(dllexport) to function CrashForExceptionInNonABICompliantCodeRange defined in src/unwinding-info-win64.cc. Note that using V8_EXPORT_PRIVATE instead does not work because 'BUILDING_V8_SHARED' is not defined.

This commit attempts to change as little behavior as possible, but it does require reordering the fields within Map to abide by Torque rules specifying that strong and weak fields must be in separate sections.

Now that function counts are based on dedicated call counters instead of FeedbackVector::invocation_count, we can enable optimizations for block coverage modes. This significantly speeds up V8 with enabled coverage: Before this CL, the web-tooling-benchmark regressed by 70% (block count coverage vs. no coverage). With this CL, the regression is reduced to 40%.
