ColdfireV4e cross compilers for EMAC instructions

Hi,

I am using gcc3.4 cross compilers to build my software for ColdFireV4e core with -mcfv4e option.
I am trying to build some of the EMAC instructions with operands acc0,acc1,acc2,acc3,accext01 and accext23.
But it is giving the following error when I use any one of the register as operand. It allows acc,mask and macsr registers.

Does the option -mcfv4e supports EMAC instructions?
Please tell me which option should I use for EMAC instructions?


gmake all
gmake: *** Warning: File `Makefile' has modification time in the future (2004-06-02 19:04:43 > 2004-06-02 19:02:48.091998)

m68k-unknown-linux-gnu-as --gdwarf2 -mcfv4e  -o reset.o  reset.s
reset.s: Assembler messages:
reset.s:47: Error: bad _expression_
reset.s:47: Error: parse error -- statement `move.l %a5,%accext01' ignored
gmake: *** [reset.o] Error 1

Thanks
Hari Krishna K.
