X-Git-Tag: POST_NATIVE_TLS_MERGE^2~76^2~4
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=af3354dc43ae3c4bc6c9a9fb74aee2d9c2f406e3;p=php

Improved specialisation $this variable accessed through IS_UNUSED operand must be IS_OBJECT, so we don't have to check for its type or perform dereference.
