From c23734c45fb1239406d054039a0f56413b955eb9 Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Tue, 23 Jan 2018 17:03:26 -0800 Subject: gcc: Upgrade 7.2 -> 7.3 The static PIE patch was updated by Juro Bystricky to work with gcc 7.3. This update from the stable gcc 7 branch includes the retpoline functionality which is useful to assist with recent security issues. Two backported patches were dropped as they're included in 7.3.
