Andreas Schwab - July 10, 2012, 11:48 a.m.
To avoid having to include tree.h in resource.c move the body of
EPILOGUE_USES to m68k.c.  Tested on m68k-linux.

Andreas.

	PR bootstrap/53913
	* config/m68k/m68k.c (m68k_epilogue_uses): New.
	* config/m68k/m68k.h (EPILOGUE_USES): Use it.
	* config/m68k/m68k-protos.h (m68k_epilogue_uses): Add prototype.
