+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.
