- Remove flag --block-concurrent-recompilation and its implementation, including %UnblockConcurrentCompilation. - Rewrite tests that used it in terms of the primitives introduced in my previous CL: https://chromium-review.googlesource.com/c/v8/v8/+/3071400/ - Remove "sync"/"no sync" arguments from %GetOptimizationStatus, assertOptimized, etc. These are now always "no sync": they don't do any magic. - Remove "if %IsConcurrentRecompilationSupported then quit" from some tests in favor of --concurrent-recompilation in their Flags line.

This reverts commit 91c8be95. RCS should not be exposed through the API or the inspector protocol as they are meant as an internal debugging feature. The only regularly tested and supported way is through chrome-tracing. Given that this was used mostly for an experiment to analyse chrome's performance, we can use pprof support as a replacement.

In Blink's version of Oilpan, GCInfo objects would reside in .bss and a table would translate between an index and the .bss address. Upon retrieving a GCInfoIndex, the slow path merely passes a .bss pointer to a slow path setup method to create the table mapping. In cppgc, we set up GCInfo entries directly in the table. This is slightly faster for actually using GCInfo objects as there's no indirection between table and .bss, and it also saves one pointer (the indirection) per type that is set up. The downside of this approach is that individual components of a GCInfo objects, that are all type-dependent, need to be passed to the conditional setup method. Since GCInfo indices must be retrieved on each allocation, this pollutes the fast path with additional instructions. However, GCInfo components are actually known at compile-time for many objects. In such cases, we can use a compile-time static dispatch to encode the known parameters in different functions. This saves around 40KiB of memory on ChromePublic.apk and also creates a more compact fast path for allocation.

InstructionSelector::ZeroExtendsWord32ToWord64 assumes that a Load[kRepWord8|kTypeInt32] generates a zero-extended value. This assumption makes sense, but was not fulfilled by the instruction selector which emitted an "ldrsb" instruction which sign-extended to the full 64-bit register. This CL fixes that by introducing a separate "LdrsbW" instruction which is selected if we are sign-extending an 8-bit value to 32-bit.

This reverts commit 2261e053. Reason for revert: No issues with the CL, but it is taking the last two available opcodes on arm64 (we use 9 bits to encode it, so we are limited to 512 opcodes). We need to land a security fix which includes the addition of two opcodes. Before relanding this, we need to figure out a strategy to either reduce opcodes, or use one more bit to encode them.

Previously V8 was reusing the error fur duplicate declarations, using the private name for class fields or the class name for class methods as the redeclared identifier. class A { constructor(o) { return o } } class B extends A { #x } class C extends A { #x() {} } let D = (0, class extends A { #x() {} }); new B(new B({})) // Identifier '#x' has already been declared new C(new C({})) // Identifier 'C' has already been declared new D(new D({})) // Identifier '' has already been declared This patch changes it to use error messages that better explain what's happening: new B(new B({})) // Cannot initialize #x twice on the same object new C(new C({})) // Cannot initialize private methods of // class C twice on the same object new D(new D({})) // Cannot initialize private methods of // class anonymous twice on the same object I initially tried to use the same message for both fields and methods, but the problem with that is that when initializing fields we only have access to the field name, while when initializing methods we only have access to the class name (using the "private brand" symbol). However, almost all the error messages are different for private fields and for methods so this shouldn't be a problem.

Previously the V8 inspector would report native accessors, whose getter evaluates to a value without causing a side effect, as own data properties. But then the DevTools front-end will not be able to tell whether that accessor was actually an own property or just an inherited accessor. The reason for reporting them as own properties in the first place was to ensure that these properties show up in the object's preview. But that we can handle differently by just marking these properties as synthetic internally and including them in the preview.

Move the implementation into shared macro-assembler. TurboFan and Liftoff for both ia32 and x64 can now share the implementation. No functionality change expected.

The concurrent version was added recently in crrev.com/c/3085262. - UnusedPropertyFields requires the MapUpdater lock. - instance_descriptors must be read atomically on the bg thread. Finally, there appears to be a false positive report for the pattern: x = is_concurrent ? foo(kAcquireLoad) : foo(); Here, clang emits code that executes both the atomic and nonatomic reads when is_concurrent is true. Needs more investigation.

fetch_or (lock-prefixed-or on x86) is emulated with branching on armv7/armv8 and therefore generates more instructions. This improves android-binary-size by 45K. It should also improve performance.
