Inline the RememberedSetAction and SaveFPMode flags directly into the RecordWrite stubs: - Save two register for input arguments - Avoid branches in the RecordWrite stubs We end up with 2 stubs for the EphemeronKeyBarrier and 4 stubs for RecordWrite. Due to more inlined calls we have roughly 1KiB more builtins code for RecordWrite currently. We will address this in the future by splitting out common code into a separate stub. There is no additional code size overhead for EphemeronKeyBarrier. This saves 4 to 8 bytes on x64 per RecordWrite call and 2.5% sparkplug code size reduction on d3.min.js.
