There is some code common to both wide and extra wide that we are able to hoist up since they do not affect the flags after testing to see which version to use.

This CL removes the StoreBuffer and inserts slots into the RememberedSet directly from within the RecordWrite builtin. Only calls into C code when either the SlotSet-array or the bucket is not allocated. This avoids filling the store buffer up with duplicates or due to a write-heavy workload and then blocking the main thread on store buffer processing.

Bytecodes used by the regular expression interpreter often occur in specific sequences. The number of dispatches in the interpreter can be reduced if those sequences are combined into a single bytecode. This CL adds a peephole optimization pass for regexp bytecodes. This pass checks the generated bytecode for pre-defined sequences that can be merged into a single bytecode. With the currently implemented bytecode sequences a speedup of 1.12x on regex-dna and octane-regexp is achieved.

The decompression eliminator changes is a workaround to ensure that the result of comparisons of two constant Smis is still a constexpr (the failing test is cctest/test-torque/TestLoadEliminationFixed). Better optimizations will be landed in a follow-up CLs.

InvalidateRecordedSlots needs to invalidate old-to new objects unconditionally. Checking slot_set_[OLD_TO_NEW] is not enough, since the sweeping_slot_set_ could still contain slots. ClearRecordedSlot in MigrateFastToFast is not necessary as well. This is only required in DeleteObjectPropertyFast since we might potentially shrink the object.

It looks like codegen on ia32 may sometimes miss a byte during emit_arith. Our working theory is that this happens because `length` in emit_operand, for whatever reason, is 0 and we thus do not advance `pc_` correctly. The tentative fix is to use EMIT to increment the pc_ on each single write instead of relying on `length`.

A lot of the instructions in RO_OP_LIST do not require temp registers in the codegen, but a temp register is emitted. We split RO_OP_LIST into two lists, one which requires temp registers RO_OP_LIST_ONE_TEMP, and RO_OP_LIST is now for instructions that do not use temp registers. There are a couple more instructions currently in RO_OP_LIST, but use scratch registers in the codegen, those can be cleaned up to use temp registers and then moved into RO_OP_LIST_ONE_TEMP.

But this is also pretty intern-dependent with harmony_intl_add_calendar_numbering_system and should be launched all together to be meaningful. https://github.com/tc39/ecma402/pull/349/ #349 Normative: Allow calendar to determine choice of pattern https://github.com/tc39/ecma402/pull/351 #351 Normative: Permit relatedYear and yearName in output Bug: v8:9155 Change-Id: I67cd6bba6276bbb995186a9fe6202429d724ba61 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1588401Reviewed-by:

Since https://crrev.com/c/1771783 the mutator owns the old-to-new remembered set, while the sweeper modifies the sweeping-slot-set. This allows us to update the old-to-new remembered set non-atomically. In this CL the mutator now inserts non-atomically into the remembered set. The AccessMode is now explicit for Insert-operations as well.
