(From update of attachment 21363)
Landed this patch, it was a 2% improvement after a slight random change that
should have been a slowdown - I've moved VM_CHECK_EXCEPTION() out of else
block. Applying the same change to bitops regresses performance, though.
On disassembly, I saw a lot of changes everywhere in Machine::executePrivate,
but I can't tell what gcc was thinking. There are also changes in completely
unrelated places, such as base64 encoding and registerThread().
