From 8103659e35edffe864ad49ac4be3a40dae0785a0 Mon Sep 17 00:00:00 2001 From: Iain Sandoe Date: Sat, 12 Oct 2019 19:20:43 +0000 Subject: [PATCH] [Darwin] Suppress emitting empty ctor/dtor sections. Older versions of GCC emit empty .constructor/.destructor sections whenever building for C++. In fact, these sections are only used for kernel mode code - so don't emit them unless that's what we're building. gcc/ChangeLog: 2019-10-12 Iain Sandoe * config/darwin.c (darwin_file_end): Only emit empty CTOR/DTOR sections when building kernel extension code.
