From 9d9f97ca5d1ceba66677bf406c9b31027dc1f22e Mon Sep 17 00:00:00 2001 From: Waldemar Brodkorb <wbx@openadk.org> Date: Fri, 19 Aug 2016 13:54:46 +0200 Subject: [PATCH] libgcc: fix DWARF compilation with FDPIC targets The build of unwind-dw2-fde-dip.c currently fails for FDPIC targets with the following error: libgcc/unwind-dw2-fde-dip.c:167:31: error: storage size of 'load_base' isn't known struct elf32_fdpic_loadaddr load_base; This patch addresses that by defining load_base with the appropriate type on FDPIC targets. It has been tested on FRV and Blackfin. Fixes PR gcc/68468.
