Dear Mr Ben,
When I was doing an opcodes port using CGEN following the
manual:(http://sources.redhat.com/cgen/docs-1.0/cgen_5.html#SEC163)
1.Run guile.
2.(load "dev.scm"). This loads in a set of interactive development
routines.
3.(load-opc). Load the opcodes support.
4.Edit your `cpu/<arch>.cpu' and `cpu/<arch>.opc' files.
The `.cpu' file is the main description file.
The `.opc' file provides additional C support code.
5.(cload #:arch "cpu/<arch>")
6.Run each of:
(cgen-desc.h)
(cgen-desc.c)
(cgen-opc.h)
(cgen-opc.c)
(cgen-ibld.in)
(cgen-asm.in)
(cgen-dis.in)
(cgen-opinst.c) -- [optional]
7.Repeat steps 4, 5 and 6 until the output looks reasonable.
8.Add dependencies to `opcodes/Makefile.am' to generate the eight opcodes
files (use the M32R port as an example).
9.Run make dep from the `opcodes' build directory.
10.Run make all-opcodes from the top level build directory
I had the following questions:
What is the directory "opcodes" in step 8, does it refer to the opcodes
directory in the binutils(I have downloaded binutils-2.12 from the gnu
ftp)package?
What does "Add dependencies to "opcodes/Makefile.am" mean?
What are the eight opcodes files?
In what directory should I run the make instruction in step 9 and 10?
By the way, could you please give me an explanation about port?
Thanks for your help!

Yes, but the opcodes build directory needs to be configured for your
target, not a native build.

See opcodes/Makefile.am and look at, for example, the fr30 port.
Mimic what was done for that port.
source> What are the eight opcodes files?
In the case of the fr30 port:
fr30-asm.c fr30-desc.h fr30-ibld.c fr30-opc.h
fr30-desc.c fr30-dis.c fr30-opc.c

What kind of explanation are you looking for, specifically?
Cheers, Ben
