From: Bernd Edlinger Date: Mon, 4 Jan 2021 20:40:41 +0000 (+0100) Subject: Fix building gdb with gcc-4.x X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=58eadc4b691b5c943a9b8879420242ffc6d498c7;p=deliverable%2Fbinutils-gdb.git Fix building gdb with gcc-4.x Since is_trivially_default_constructible was not implemented before gcc-5 it cannot be used with gcc-4.x. Fix the build by using conditional compilation around that line. Use the equivalent is_trivially_constructible instead, since we already have HAVE_IS_TRIVIALLY_CONSTRUCTIBLE for that purpose.
