From d15c30e31950e27e72f50777dde00f63400ed80b Mon Sep 17 00:00:00 2001 From: Giuliano Procida Date: Mon, 13 Jun 2022 15:25:30 +0100 Subject: [PATCH] crc_changed: eliminate copying of shared_ptr values As pointed out in a review of similar code, it is possible to avoid copying a couple of shared pointers in this function, by taking references instead. This commit also splits declarations to one per line and removes the unnecessary parentheses around the return expression. * src/abg-comp-filter.cc (crc_changed): Take references to avoid std::shared_ptr copying. Split declarations into one per line. Remove unnecessary return expression parentheses.
