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

["Gina Verlekar" <GinaV at KPITCummins dot com>]

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.

  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! :)
