Before the introduction of exception handling in the compile fuzzer, stack overflows were deterministic because they always caused the whole stack to be unwound. With support for exception handling, the stack overflow exception can be caught and is a source of nondeterminism. Flag the interpreter result as such in this case so that we skip the correctness check.

It could happen (e.g. with --stress-background-compile) that the main thread blocks for a background thread but the background thread requests a GC from the main thread. This would result in a deadlock. Avoid this by parking the main thread for potentially blocking operations and allow allocations while the main thread is parked. This CL introduces new states for the main thread: CollectionRequested and ParkedCollectionRequested. These states will force Safepoint(), Park() and Unpark() on the main thread into slow paths. The slow path can then perform a GC on the main thread - right before parking or after the main thread got unparked.

The build time flag v8_dict_mode_prototypes is ill-named, because it does not control whether properties are kept in dictionary mode (this is done by the v8_dict_property_const_tracking flag), but instead it controls if SwissNameDictionary or NameDictionary is used as the property backing store for all dictionary mode objects. This CL renames the flag and updates its description. Change-Id: If1337838d1b6d8f089c281a77d9ef7cfd4007220 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2786859Reviewed-by:

With the addition of deoptimizing to baseline, we mark the begin of every bytecode as a valid jump target in baseline code (Required for CFI on arm64). Therefore we can omit marking excpetion handler positions and binds at the beginning of the bytecode as valid jump targets now.

In inspector-task.cc, the frontend and backend runners are explicitly joined before going out-of-scope. On POSIX platforms, calling pthread_join() on a thread that has already been joined has undefined behavior. For example, under the musl C runtime library, a successful call to pthread_join() will unmap the pthread_t thread information region, and calling pthread_join() again will result in SIGSEGV.

AddImmediate ends up pushing repeated immediates very often unecessarily. Add support for Int64 immediates being inlined into InstructionOperand if they fit into the payload (which is almost always the case). Also add a seperate rpo_immediate vector for RPO numbers to avoid having to add them to the immediates_ vector multiple times. Ideally the RPO values would also be inlined, however JumpThreading needs to patch RPO targets throughout the instruction stream, so we need an indirection.
