This is bad because r1 is clobbered by PLT. -The another functions listed in the standard libgcc-std.ver which -possively have similar problem are __ashlsi3, __ashrsi3 and __lshrsi3, -though these are used only by SH1/2. -The patch below simply uses an SH specific libgcc-std.ver which drops -these functions.
