*
+ * Rodney Radford <rradford@mindspring.com> 17-Aug-2004.
+ * Added x86_64 support.
+ *
* Miles Bader <miles@gnu.org> added NEC V850E support.
*
* Modified by Bryan Rittmeyer <bryan@ixiacom.com> to support SH4
* very minor changes required to also work with StrongArm and presumably
* all ARM based systems.
*
+ * Yoshinori Sato <ysato@users.sourceforge.jp> 19-May-2004.
+ * added Renesas H8/300 support.
+ *
* Paul Mundt <lethal@linux-sh.org> 08-Aug-2003.
* Integrated support for sh64 (SH-5), from preliminary modutils
* patches from Benedict Gaster <benedict.gaster@superh.com>.
* These blocks should be easy maintain and sync with obj_xxx.c in modutils.
*
* Magnus Damm <damm@opensource.se> added PowerPC support 20-Feb-2001.
