dear Mr,

when we tried to build the GAS test suite following the CGEN manual 
(http://sources.redhat.com/cgen/docs-1.0/cgen_5.html#SEC165)

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. 

When we proceeded to the 4th step, we got the following  error messages,

% sh gas-build.sh 
 is not a GAS build directory.

we checked the "gas-build.sh" file, in the head it said:

#/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.
#
# Syntax: build.sh /path/to/build/gas
BUILD=$1
if [ ! -f $BUILD/as-new ] ; then
    echo "$BUILD is not a GAS build directory."
    exit 1
fi
.....
.....

our problem is we couldn't find the file "as-new",we didn't know when this 
file was generated? and what the function of it?
We had saw "# Syntax: build.sh /path/to/build/gas",then tried to run 
following command:
%gas-build.sh /home/student/user1/cgen/gas
but the same error occured.


Then we went on checking the "gas-build.sh" file,there was a function 
called gentest as following:
function gentest {
    rm -f a.out
    $BUILD/as-new ${1}.s -o a.out
    echo "#as:" >${1}.d
    echo "#objdump: -dr" >>${1}.d
    echo "#name: $1" >>${1}.d
    $BUILD/../binutils/objdump -dr a.out |      sed -e 's/(/\\(/g' -e 
's/)/\\)/g' -e 's/[+]/\\+/g' -e 's/[*]/\*/g' |    sed -e 's/^.*file 
format.*$/.*: +file format .*/'       >>${1}.d
    rm -f a.out
}

We noticed there are "$BUILD/as-new ${1}.s -o a.out" and " 
$BUILD/../binutils/objdump -dr a.out |......",we couldn't find 
"$BUILD/../binutils/objdump",waht the problem about this?

To sum up,our problems are
1.when these two files "as-new" and "objdump" are generated?
2.what are their functions ?

Thanks for your help!

These are programs built as part of the gas and binutils packages.  In
the case of `as-new', it is named this when built, but renamed
appropriately when it is installed with `make install'.

  source> 2.what are their functions ?

To assemble to object code and to dump object files, respectively.

It sounds like your problem is that you've not built the gas and
binutils directories.  As you've noted, they are required to generate
testsuites.

Hope this helps.
