Log:
Convert ASSIGN_ADD $a, $b into $a = ADD $a, $b, if possible.
Changed paths:
M ext/opcache/Optimizer/dfa_pass.c
So this changes $a += $b into $a = $a + $b?
What is the purpose of that...? I always use the former, because I thought
the latter created a temp value for $a + $b prior to assignment... (Maybe
I'm wrong or it's different now? :-/)
Otherwise, is the idea to "deaden" the ASSIGN_* handlers and consolidate
stuff to a common handler, thus improving CPU instruction cache usage?
Thanks,
Matt
