This is a reland of 410ca4c5 Skip new test for unsupported liftoff architecture. Previously, if there is some unsupported liftoff functions, it fall through Turbofan but recompilation didn't catch and count it. This CL fixes it by using requested_tier on finished units.

Define a macro in code-generator-ia32 to help identify cases when the shift value is an immediate/constant. In those cases we can directly emit the shifts without any masking, since the instruction selector would have modulo-ed the shift value. We also don't need any temporaries in this case.

With "Value::parseBinary" now being revamped by https://crrev.com/c/2020518 and making use of "cbor::ParseCBOR", the extra endianness check is not needed anymore as "ParseCBOR" already switches the byte order in this line: crdtp/cbor.cc void ParseUTF16String(CBORTokenizer* tokenizer, ParserHandler* out) { .... for (size_t ii = 0; ii < rep.size(); ii += 2) value.push_back((rep[ii + 1] << 8) | rep[ii]); ... "String16EndianTest" does not go through the newly added pipeline and "ParseUTF16String" is never used which makes the test redundant.

A pointer-compressed heap has the same heap limit heuristics as a 32-bit heap. Specifically, the heap limit is restricted to 1GB due to scarce virtual addresses space on 32-bit platforms. That limitation does not apply for pointer-compressed heaps which can use 4GB. This CL changes the heap limit computation to use system the pointer size instead of the tagged pointer size. Note that the young generation limit continues to use the tagged pointer size.

Allow HandleOrOffThreadHandle to implicitly convert to any of Handle, MaybeHandle, and OffThreadHandle, so that it can be used in Isolate-templated code with fewer 'get' calls. As a drive-by, allow OffThreadHandle to have an OffThreadIsolate parameter (so that HandleFor<Isolate, Foo>(x, isolate) works), and use a static_cast rather than a T::cast in the implicit upcast constructor of OffThreadHandle to prevent implicit down-casts.

Currently back references to regular objects are encoded in terms of a relative address, index by chunk index and chunk offset. This approach has the advantage of avoiding the need for a table of back-references at deserialization time, but makes strong assumptions about the way objects are organized in memory (for example, this will not work if the allocator uses a free list rather than a bump pointer). I did some quick measurements and found that the absolute number of objects and back-references is low, suggesting that simply indexing objects would work with little (or no) observable impact on peak memory use during deserialization. Indexing only back referenced objects is not implemented in this simple CL, but could fairly easily be added. Given that the existing mechanism will remain in place, I have implemented the object index by simply making chunk size one, so every object lives on its own chunk (with offset zero). This is the moral equivalent to indexing each object but is a more minimal change. Directly encoding an object index will be more efficient, the trade off made here is just to keep the change absolutely minimal. If using an object index becomes the default, this can be optimized first by only using an index for each object that is actually back- referenced (about half of all objects in my measurements), and more aggressively, a technique like register allocation could be used at serialization time to limit the number of indices to the maximum number of outstanding back-references at any time (basically a live- range analysis of back-references).

- 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.

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.

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: -

Fixes the one case after calling EnsureSourcePositionsCollected that we were still using the non-handle version of the SharedFunctionInfo.

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.

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.
