From 2414b86d21dbacc53826d375c6001d31d8ebbee2 Mon Sep 17 00:00:00 2001 From: Paul Mundt <lethal@linux-sh.org> Date: Fri, 13 Jul 2007 09:30:31 +0900 Subject: [PATCH] sh: Export div symbols for GCC 4.2 and ST GCC. GCC 4.2 can emit integer variants of the FP division routines, so these need to be exported in order to keep the modules happy. 4.1.x versions of the ST compiler have these things backported, and so also generate these symbols (whereas vanilla gcc 4.1.x does not), so handle the __GNUC_STM_RELEASE__ case to accomodate updated versions of the 4.1.x toolchain.
