 Dear Kasper,
 
 vbr and pc are special purpose registers and are not used by the gcc. =
 vbr is a control register and pc is a system register for SH.
 You are getting the error because these registers can not be used as =
 register variables. If you use any of the general purpose registers for =
 register variable, gcc will accept it.
 
 Thanks & regards
 Rekha Bhintade
