Thank you for your suggestion. 
We agree to you that a separate utility to generate a GNU archive from 
Renesas library file is better idea. We will surely implement it. It
would 
be better to invoke "ar" internally from this utility. This will help
user 
to get GNU archive directly.

  And of course, if there's a new release of binutils with a new improved
version of ar, your utility benefits automatically, without needing to
maintain the code you were going to add separately! :)

Hi,

The patch attached herewith adds a new utility 'convrenesaslib'. This
utility 
converts the input Renesas SH library file(s) to GNU archive file(s).
This utility supports only Renesas SH library files. Multiple Renesas
library 
files can be provided on command line at a time.

The usage of this utility is as follows: 
convrenesaslib filename(s)
where 'filename' is the input Renesas SH library file. 

The GNU archive which gets created has '.rlib' extension. This file is
created 
in the same directory as the Renesas library file.

An option '--remove-underscore' is provided to this utility. 
Usage:
convrenesaslib --remove-underscore filename(s) 

--remove-underscore
     This will remove all leading underscores appended to global symbols
in 
     the created GNU archive.

Changelog

2006-07-07  Gina G. Verlekar  <ginav@kpitcummins.com>
	* convrenesaslib.c: Add new file
	* Makefile.in: Modify to build convrenesaslib.c.
	* Makefile.am: Likewise.
	* configure.in: Check for Renesas SH targets to build
convrenesaslib.
	* doc/binutils.texi: Add documentation for convrenesaslib
utility.

Any comments will be appreciated.

Hi Gina,

I am sorry but I am still very unhappy with this patch.  I think the 
whole idea of having the convertrenesaslib program invoking both AR and 
OBJCOPY is a bad idea.  I really think that you should use a shell 
script to do this, and that all that convertrenesaslib should do is 
extract the object files from a Renesas format library and write them 
into the current directory.  The script can take care of the rest - ie 
collecting them together again into a GNU format archive, removing the 
underscore prefix and deleting the now archived object files.  This will 
be a much cleaner, simpler way to handle the problem.  Plus it follows 
the UNIX paradigm of having a set of small simple tools that each 
perform one task, but which can be linked together to perform quite 
complex operations.  Plus it will remove all the command line allocation 
and construction hassles that you obviously have in the current code.

Cheers

Hi Nick,

I have modified the patch as per your comments and suggestions. Please
find	
attached herewith the modified patch.

Presently I am facing some problem in adding a test case in binutils for

testing the utility. However, I have attached a separate test case for

convrenesaslib utility along with this mail, for your reference.

I will soon be adding the testcase in binutils also.

Whenever a user wants to use custom Renesas library file with a project
compiled
using sh*-linux toolchain, the leading underscores of all functions and
global	
symbols in the Renesas library file have to be removed.

If this is not done, the user will get 'undefined references' errors for
all the
functions and global symbols in the library file.

Hence a '--remove-underscore' switch is provided in the convrenesaslib
utility	
for ease of use.	

Changelog

Sorry for the delay in reviewing this patch.


Unfortunately I do not think that it is ready for inclusion into the

sources yet.  The problems that I have with it are:


  * The changes to Makefile.am mean that recreating Makefile.in

    results a warning message about the convrenesaslib_SOURCES being

    defined but not used.  You need to add it to the EXTRA_PROGRAMS

    definition.

    
  * The copyright comment at the start of convrenesaslib.c has the

    wrong address for the FSF and it says that the tool is part of GLD

    whereas in fact it is part of the GNU Binutils.


  * REPORT_BUGS_TO is defined in the bin-bugs.h header.


  * Having the "magic_num" field of the rlib_header structure be of

    the "unsigned char" type results in compile time warning messages

    when it is used as an argument to strcpy().

    
  * None of the textual output of the program has been

    internationalized.

    
  * The --remove-underscore switch is a bad idea.  It would be much

    cleaner and safer if you just invoke "objcopy

    --remove-leading-char" for yourself as a separate step after

    completing the conversion to the GNU ar format.

    
  * The indentation and formatting do not quite match up to the GNU

    Coding Standard.

    
  * The use of the program_name array looks very strange to me.  I

    think that it would be much cleaner if you left program_name as

    being the value of argv[0] and you used a different variable when

    you are constructing the ar command line.


  * There are various "magic" constants in some of the malloc() calls

    (eg + 50, or + 100) without any explanation of where they come

    from.  There are also several fixed length arrays that should not

    be fixed (eg filepath, module_name).


  * The fatal() function should be used in place of the

    printf();exit(1); combination currently used.


  * [optional] Adding a --verbose switch would be useful.  It could

    tell the user the command line it is using to invoke "ar", and

    also mention when files are being created and deleted.


  * [optional] A test case to check that the tool works would be very

    helpful.

  I agree.  Cut-n-paste duplication of a huge chunk of ar.c is a bad idea.
Creating and deleting loads of temp files in your system's cross-libs dir is a
bad idea too; who says the user doing the compile would even have write perms
there?

I took a quick look at the patch, and can't see anything that would 
prevent you
from splitting process_renesas_library_file into a seperate tool.
As I understand the patch, process_renesas_library_file function 
extracts the object files of the renesas lib,
and then you then call create_gnu_archive on the files mimicing what ar 
q does.

You could instead have (simplified):

rlibextract $(renesaslib) $(outputdir)
ar q librenlib.a $(outputdir)/*
ld $(objects) -lrenlib

rlibextract being your new tool.

It would reduce code duplication,
you would be able to maintain it with a different release cycle from 
binutils,
*and* it could be used with older binutils versions.

Wouldn't this be better? Or am I missing something?

I assume 'rlib' means 'Renesas library'? Would it not be better for the 
option to say that? I though it meant either 'relocatable library' or 
something to do with -rpath or -rlink, when I first saw it.

If the Renesas library is fully converted into a GNU archive, why isn't 
this implimented as a
separate tool? One that converts the libs only once, and be done with it 
so the user can use -l
normally. You could even integrate the tool into the build system, so it 
would be transparent
like your patches aims at being.

[PATCH] Addition of new option '--rlib' in linker for Renesas SH targets

[Gina Verlekar]

[-- Attachment #1: Type: text/plain, Size: 1769 bytes --]


Hi,

The patch attached herewith adds a new option '--rlib' to the linker.
Using this
option, Linker links a Renesas SH library file (created by Renesas
Compiler)	
with GNU object files.
'--rlib' option is supported only for Renesas SH targets.

The format of the option is:
--rlib=<filename >
where 'filename' is the Renesas SH library file to be linked.

This patch converts the Renesas library file into a GNU archive with
name	
<filename>.rlib. This file is created in the same directory as the
Renesas	
library file. This created GNU archive is then passed to the Linker for
further	
processing. 
This option can be used multiple times to link multiple Renesas SH
library	
files.

Patch has been generated for latest snapshot of binutils
(binutils-060621).	
No new regression failures are found.


Changelog

2006-06-26  Gina G. Verlekar  <ginav@kpitcummins.com>

	* lexsup.c: Add --rlib option for linking Renesas SH library
file.	
	* ldrlib.c: Add new file for processing Renesas SH library file.

	* Makefile.in: Modify to include ldrlib.c file for compilation.

	* Makefile.am: Likewise.

	* ld.texinfo: Add documentation for linker option '--rlib'.

	* configdoc.texi: Likewise.	

Any comments will be appreciated.
