From 644a512e560147324ecf74ebce5e336bc57dd7bf Mon Sep 17 00:00:00 2001 From: Julius Werner Date: Tue, 25 Aug 2020 16:00:44 -0700 Subject: symbols: Change implementation details of DECLARE_OPTIONAL_REGION() It seems that GCC's LTO doesn't like the way we implement DECLARE_OPTIONAL_REGION(). This patch changes it so that rather than having a normal DECLARE_REGION() in and then an extra DECLARE_OPTIONAL_REGION() in the C file using it, you just say DECLARE_OPTIONAL_REGION() directly in (in place and instead of the usual DECLARE_REGION()). This basically looks the same way in the resulting object file but somehow LTO seems to like it better.
