From 9b9d6b2a4f6df5544a10de44760755fe757259e5 Mon Sep 17 00:00:00 2001 From: Takashi YOSHII Date: Mon, 11 Aug 2008 20:12:52 +0900 Subject: [PATCH] sh: Provide a FLAT_PLAT_INIT() definition. SH needs this in order to make sure that r4 has a sane value at process entry time, which the libc expects has already been taken care of. Fixes random crashes in flat binaries.
