I do configure in the gas subdirectory.

Try using mipsx3-elf or mipsx3-aout.  Does that work?

Hi David,

> surely. I had run "autoconf" and "automake" before doing "./configure"

In which case are you running 'configure' from the top level of the
source directory, or from inside the gas subdirectory ?  If the former
then you probably want to edit the "config.sub" file to add your
target.

If this does not help, perhaps you could send me a (small) copy of the
command you are running and its output.

Cheers
        Nick

Hi Nick,
    
   First thanks for your reply.

Yes, MIPSX3 is a MIPS processor variant. But I find the gas MIPS is too 
complicated to integrate the MIPSX3 in it. Although the codes of 
tc-mipsx3.* is originated from tc-mips.*, I think treating MIPSX3 as a new 
processor maybe somewhat easier.

I have rename tc-mipsx3.c/tc-mipsx3.h to tc-mips.c/tc-mips.h in order to 
compile the porting codes. 

bash#./configure --target=mips-big-aout

I got a new "as" that can translate asm codes to binary codes. But it 
generates coff file, what I want is aout. This situation also confused me 
so much.

surely. I had run "autoconf" and "automake" before doing "./configure"

Is the "mipsx3" a MIPS processor variant ?  If so you might want to
consider starting with the current mips target rather than the mmix.

> I can't configure the  target to mipsx3 despite I update the

Did you run "autoconf" (after changing configure.in) and then
"automake" (after changing Makefile.am) in the gas source directory ?
These tools create the "configure" and "Makefile.in" files
respectively which are what are actually used when configuring gas.

Cheers

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
