- In log.cc, we used InstructionStart() for code create events, but the Code object address for code move events. Change to use InstructionStart() for both. - The symbol table contains some kind of virtual address, not file offsets. They happened to be identical in the past but are no longer, probably due to toolchain changes. Now we use objdump to figure out the difference between virtual addresses and file offsets. - When a new code object happened to be created at the same address as a previous one, we wouldn't update it. This is indeed wrong, as predicted in a TODO by Jaro. - For 64bit addresses, using >>> is wrong, now replaced with division.

Port 59bda196 Original Commit Message: This CL adds the "WasmDebugBreak" builtin for x64, ia32, arm and arm64. It stores all wasm parameter registers to the stack and calls the respective runtime function. The runtime function does not do anything yet, but the inspector/debugger/wasm-set-breakpoint-liftoff test will already execute both the builtin and the runtime function.

Delay completing marking (and thus the atomic GC pause) during JS executions, increasing the chance to finalize the garbage collection from a task. This is beneficial as it avoids stack scanning which is expensive and can keep alive outdated objects in case of unified heap. Completing will be delayed at most by some overshoot factor (10%). In addition, the GC keeps the weighted average of previously recorded time to incremental marking task invocations and bails out if the task is expected to arrive too late. Reland: Do not schedule a delayed task when marking has already been finalized. This reverts commit 1775684e.

When converting JS values to wasm, we have a fast path for smi inputs. This CL makes this fast path faster by making the alternative (calling ToNumber) deferred. That slow path will be slower then, especially since register allocation (in particular the spilling decisions) are less optimal.

The source position is set to the function call (console.log) not the spread (..x), in the bytecode generator, as the spread operation is done as part of the CallWithSpread bytecode. The CallPrinter stops at the function call and doesn't look at the arguments as well (in CallPrinter::VisitCall) to see if the error is from an incorrect spread operation. With this patch, we pass some state to the CallPrinter in the CallWithSpread error case and check that in CallPrinter::VisitCall before returning. For the given source string: ``` x = undefined; console.log(1, ...x); ``` Previously, the error was - ``` test.js:2: TypeError: console.log is not iterable (cannot read property Symbol(Symbol.iterator)) console.log(1, ...x); ^ TypeError: console.log is not iterable (cannot read property Symbol(Symbol.iterator)) at test.js:2:9 ``` Now, the error is - ``` _test.js:2: TypeError: x is not iterable (cannot read property undefined) console.log(1, ...x); ^ TypeError: x is not iterable (cannot read property undefined) at _test.js:2:9 ``` Bug: v8:10038 Change-Id: I199de9997f1d949c6f9b7b4f41d51f422b8b5131 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2037431Reviewed-by:Leszek Swirski <leszeks@chromium.org> Commit-Queue: Sathya Gunasekaran <gsathya@chromium.org> Cr-Commit-Position: refs/heads/master@{#66131}

If new Liftoff code is generated but we already have either Liftoff or TurboFan code, we still want to install and use the new Liftoff code if we are in debugging. This logic can probably be simplified again when the "tier down to liftoff on Debugger.enable" logic is fully implemented. I left a TODO to revisit the logic later.

This implements the runtime function for DebugBreak functionality in Liftoff code. We find the Liftoff frame on the stack, get the position within that frame, find breakpoints set at that position, and then call {OnDebugBreak} with these breakpoints. Note that one additional change is needed in order to make this actually hit the right breakpoints. Once everything is in place, we will see a change in the expected output in the wasm-set-breakpoint-liftoff test.

The instruction selector assumed for Word32AtomicPairCompareExchange nodes that if there exists a Projection(1) user, then there also exists a Projection(0) user. This, however, is not the case, because TurboFan eliminates unreachable nodes. The missing projection node lead to a failed DCHECK in the register allocator. With this CL we allocate the right registers for the existing projections, and allocate the other needed registers as temp registers.

Change the TPH API so that it uses v8::internal::Isolate rather than v8::isolate. The third party heap is within the internal namespace and ultimately needs access to v8::internal::Isolate to do things such as adding code ranges. There's no reason for it to use v8:Isolate.

The debug side table is indexed by pc offset. Offsets change if breakpoints are added or removed, hence we cannot reuse the debug side table when compiling another version of the function (with a different set of breakpoints). Thus store the debug side table per code object instead of per function.

Delay completing marking (and thus the atomic GC pause) during JS executions, increasing the chance to finalize the garbage collection from a task. This is beneficial as it avoids stack scanning which is expensive and can keep alive outdated objects in case of unified heap. Completing will be delayed at most by some overshoot factor (10%). In addition, the GC keeps the weighted average of previously recorded time to incremental marking task invocations and bails out if the task is expected to arrive too late.

TracedReference is supposed to be as light-weight as possible without destructor or other callbacks, essentially just representing a plain managed reference.
