Subject: [PATCH] sh: remove RELOC_HIDE on exception handlers and syscall routines
Date: Sun, 08 Aug 2010 20:53:45 +0000 [thread overview]
Message-ID: <1281300825-3327-1-git-send-email-namhyung@gmail.com> (raw)
remove unneccessary use of RELOC_HIDE(). It does simple addition of ptr and
offset and in this case (offset 0) does practically nothing. It does NOT do
anything with linker relocation.
