From c6de002617c199f80f9a2a713dffc263bdc69b81 Mon Sep 17 00:00:00 2001 From: Yoshinori Sato Date: Thu, 31 Jul 2008 00:07:29 -0700 Subject: Missing symbol prefix on vmlinux.lds.h ARCH=h8300: init/main.c:781: undefined reference to `___early_initcall_end' Same problem have __start___bug_table __stop___bug_table __tracedata_start __tracedata_end __per_cpu_start __per_cpu_end When defining a symbol in vmlinux.lds, use the VMLINUX_SYMBOL macro. VMLINUX_SYMBOL adds a prefix charactor. You can't just use straight symbol names in common header files as they dont take into consideration weird arch-specific ABI conventions. in the case of Blackfin/h8300, the ABI dictates that any C-visible symbols have an underscore prefixed to them. Thus all symbols in vmlinux.lds.h need to be wrapped in VMLINUX_SYMBOL() so that each arch can put hide this magic in their own files.
