Maciej W. Rozycki 8225203377 MIPS/LD/testsuite: Adjust match patterns for special section indexes
Update `readelf' symbol table dump match patterns to handle SHN_MIPS_DATA
and SHN_MIPS_TEXT special section indexes produced by the IRIX ELF format
variation used with a number of MIPS targets and printed by `readelf' as
PRC[0xff02] and PRC[0xff01] respectively, correcting LD test suite
failures:

extra regexps in .../ld/testsuite/ld-elf/comm-data1.sd starting with "^ +[0-9]+: +[0-9a-f]+ +0 +OBJECT +GLOBAL +DEFAULT +[0-9]+ +foo$"
EOF from dump.out
FAIL: Common symbol override test (auxiliary shared object build)

extra regexps in .../ld/testsuite/ld-elf/pr21703-shared.sd starting with "^ +[0-9]+: +[0-9a-f]+ +4 +FUNC +GLOBAL +DEFAULT +[0-9] +foo@FOO$"
EOF from dump.out
FAIL: PR ld/21703 shared

extra regexps in .../ld/testsuite/ld-elf/comm-data1.sd starting with "^ +[0-9]+: +[0-9a-f]+ +0 +OBJECT +GLOBAL +DEFAULT +[0-9]+ +foo$"
EOF from dump.out
FAIL: MIPS o32/copyreloc common symbol override test (auxiliary shared object build)

extra regexps in .../ld/testsuite/ld-elf/comm-data1.sd starting with "^ +[0-9]+: +[0-9a-f]+ +0 +OBJECT +GLOBAL +DEFAULT +[0-9]+ +foo$"
EOF from dump.out
FAIL: MIPS o32/nocopyreloc common symbol override test (auxiliary shared object build)

observed due to file contents like:

     7: 5ffe02e8     0 OBJECT  GLOBAL DEFAULT PRC[0xff02] foo

shown by `readelf -s' vs:

 +[0-9]+: +[0-9a-f]+ +0 +OBJECT +GLOBAL +DEFAULT +[0-9]+ +foo

pattern expected, triggered by widening testing to these targets by commit
05a5feafdd ("Rewrite check_shared_lib_support").

	ld/
	* testsuite/ld-elf/comm-data1.sd: Alternatively accept
	`PRC[0xff02]' in place of a regular section index.
	* testsuite/ld-elf/pr21703-shared.sd: Likewise `PRC[0xff01]'.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
