In preparation for upcoming work on Torque function pointers. This table will be used to look up the entry address in order to call there directly without going through the (on-heap) trampoline.

When selecting the frame above the V8_Dcheck method (at the DCHECK location), it helps enormously to immediately see the error message generated by the DCHECK. This extends the dcheck_stop_handler to find and print this message. Drive-by: Speed up the handler by stopping after the first V8_Dcheck frame.

Jakob Kummerow authored
The new ObjectPtr design makes non-inlined helper functions a little more expensive because "this" is always a pointer where pass-by-value would be more efficient, which is an issue for functions whose size puts them right at the threshold of getting inlined or not. String::Get falls into this category when called from RegExpFlagsFromString. In this case, we can do even better than restoring inlineability by fine-tuning the control flow a bit. This should repair the regression in crbug.com/910573 Bug: chromium:910573 Change-Id: Ie6b68ef01cd978ec502d8d6c1da788c77422dce7 Reviewed-on: https://chromium-review.googlesource.com/c/1369087 Commit-Queue: Jakob Kummerow <jkummerow@chromium.org> Reviewed-by:

This overlays the "arguments count" and the "deoptimization index" fields within a safepoint entry. It allows for a larger value of arguments count to be stored in entries that do not contain a deoptimization index. Currently the arguments count is unused in TurboFan, but it will be used to handle reference type arguments in WebAssembly code.

Different threads check this flag multiple times per function, and currently all of them synchronize on a single mutex. It's not even a reader-writer-lock, hence they might block each other just for checking whether an error has been set. Threads don't rely on precise information here, this is just a check to abort early if compilation failed anyway. Also in the current implementation, no ordering is guaranteed on this error field. We can avoid taking the mutex by turning the field into an atomic pointer. It will be updated at most once, from nullptr to the first error detected. To check whether an error is set, we can even use relaxed memory order, since we won't look into the object behind the pointer.

Post-stub-to-builtin migration, all explicit connection between descriptors and their associated ASM code has been lost. This restores the connection where possible. Builtins without an associated descriptor are marked with the DummyDescriptor. Drive-by: alpha-sort the descriptor list. Drive-by: use Builtins::CallableFor in code factory.

The additional variant does not use wrapper disabling phase tests and negated outcome processor. This allows to ensure that tests marked FAIL_PHASE_ONLY, do actually fail without it.

With V8 lite mode we don't allocate feedback vectors always. This cl adds a new NO_FFEDBACK IC state and uses it use/update feedback only when there is a valid feedback vector.

The disassembler expects the actual instruction area of a code object (i.e. from InstructionStart() to the first embedded metadata section such as the handler table) to contain only valid instructions. This changes asm::DataAlign() to pad with 0xcc bytes, which are int3 instructions on x64 and ia32.
