I'll assume they're okay for now: you have other problems:

Well, you need to overcome this problem.  A properly target assembler is
essential to making progress: it is a prerequisite to building a new
test suite.  Check out a copy of the whole binutils+cgen kit from the
sources.redhat.com /cvs/src repository, configure a build tree with
"--target=m32r", then run "make".  Please report any build failures
if you cannot solve them by yourself.

For this step, it's important to ensure that cgen will pick the
right cpu model for generating the subsequent tests.  For the
m32r, you may need to say
	% make ARCH=m32r ISA=m32r gas-test

Very strange: I don't see any public cpu models that include an
"add3" instruction.  Could you forward a copy of the generated
allinsn.s file?

Also, are you sure that the assembler being used is an assembler
configured for this same target?

problems about "building a GAS test suite"

Dear Mr Ben,
     Sorry for bothering you again, but I think I've met a big problem. 
When I was building a 

GAS test suite following the CGEN manual(take m32r for example):

1.cd to the CGEN build directory 

2.make gas-test At this point two files have been created in the CGEN build 
directory: 

`gas-allinsn.exp' and `gas-build.sh'. The `gas-build.sh' script normally 
requires one command 

line argument: the location of your `gas' build directory. If this argument 
is omitted, the 

script searches in `../gas' automatically. 

3.Copy `gas-allinsn.exp' to 
`toplevel/gas/testsuite/gas/<arch>/allinsn.exp'. 

4.sh gas-build.sh At this point directory tmpdir contains two files: 
`allinsn.s' and 

`allinsn.d'. File `allinsn.d' usually needs a bit of massaging. 

5.Copy `tmpdir/allinsn.[sd]' to `toplevel/gas/testsuite/gas/<arch>' 

6.Run make check in the `gas' build directory and massage things until 
you're satisfied the 

files are correct. 

7.Check files into CVS.

I went through the first 3 steps successfully. In step 4, when I run "sh 
gas-build.sh (the 

directory where gas is build)", I got such error mssages:

allinsn.s: Assembler messages:
allinsn.s:8: Error: too many memory references for `add'
allinsn.s:12: Error: no such instruction: `add3 fp,fp,00'
allinsn.s:16: Error: too many memory references for `and'
allinsn.s:20: Error: no such instruction: `and3 fp,fp,0'
allinsn.s:24: Error: too many memory references for `or'
allinsn.s:28: Error: no such instruction: `or3 fp,fp,00'
allinsn.s:32: Error: too many memory references for `xor'
allinsn.s:36: Error: no such instruction: `xor3 fp,fp,0'
allinsn.s:40: Error: no such instruction: `addi fp,0'
allinsn.s:44: Error: no such instruction: `addv fp,fp'
allinsn.s:48: Error: no such instruction: `addv3 fp,fp,0'
...


I checked the file "gas-build.sh", it's head writes
#/bin/sh
# Generate test result data for m32r GAS testing.
# This script is machine generated.
# It is intended to be run in the testsuite source directory.

It sound's that the instructions given in this file should be m32r's 
instructions, but why the 

above message shows "no such instruction", where on earth does the 
contradiction lie?


I'm very anxious to know the answer, thank you! 
 
                                                                  
yours:Jacky
