problem of porting gas

["David zhang" <davidzhl at hotmail dot com>]

Hi All,
Probably a silly  question but please excuse me.
  I have a problem in the procedure of port gas to mipsx3. I have taken the 
mmix porting as the example.I can't configure the  target to mipsx3 despite 
I update the configure.in and makefile.am like the following.

  Can u give me some pointers in this regard ?

I have added the mipsx3 target in 
  *Makefile.am 
  *configure.in,

created the files
  * /config/tc-mipsx3.c
  * /config/tc-mipsx3.h
  * ../include/opcode/mipsx3.h
  * ../opcodes/mipsx3-opc.c 


What's wrong about this following?

#bash: ./configure --target=mipsx3
.......
checking target system type... Invalid configuration `mipsx3': machine 
`mipsx3' not recognized
......
configure: error: GAS does not know what format to use for target
