Need help on how to port GAS

[pnn98017]

Hi all,

We're two students at Mälardalens University in Sweden who are trying to 
port gas, ld & gdb to a new architecture. It's a very simple 32 bit RISC 
processor. We've been looking around for any documentation that can help us 
but have come up short so far. From a previous posting on this board we 
have found that the following files are the ones to write/change:

>gas/config/tc-FOO.h - Customisation of generic parts of the assembler
>gas/config/tc-FOO.c - Port specific parts of the assembler
>include/{coff|elf}/FOO.h - Port specific header file
>include/opcodes/FOO.h - Port specific ISA encoding
>opcodes/FOO-dis.c - Port specific disassembler routines
>opcodes/FOO-opc.c - Port specific ISA encoding
>bfd/{elf32|coff}-FOO.c - Port specific relocation handlers
>bfd/cpu-FOO.c - Port specific description of the CPU
>ld/scripttempl/FOO.sc - Port specific linker template file
>ld/emulparam/FOO.sh - Port specific linker customisation

You will also need to add support for your chip to the various 
configuration files:
>gas/configure.in
>opcodes/configure.in
>bfd/configure.in
>bfd/config.bfd
>bfd/archures.c
>bfd/reloc.c
>ld/configure.in
>ld/configure.tgt
>include/dis-asm.h

We would appreciate any additional information on how a port is done or if 
you know of people who have done a porting.
Thanx.
