Eric Botcazou f8745e1cd1 PR ld/22972 on SPARC.
This is a regression for the corner case of a hidden symbol in a PIC/PIE
binary which is subject to both a new-style GOTDATA relocation and an
old-style GOT relocation.  In this case, depending  on the link order,
the R_SPARC_RELATIVE dynamic relocation for the GOT slot needed because
of the old-style relocation can be replaced with R_SPARC_NONE coming
from the GOTDATA relocation.

The fix simply records whether an old-style GOT relocation is seen for a
symbol and prevents the R_SPARC_NONE from being generated in this case.

bfd/
	* elfxx-sparc.c (struct _bfd_sparc_elf_link_hash_entry): Add new flag
	has_old_style_got_reloc.
	(_bfd_sparc_elf_check_relocs) <GOT relocations>: Set it for old-style
	relocations.  Fix a couple of long lines.
	(_bfd_sparc_elf_relocate_section) <R_SPARC_GOTDATA_OP>: Do not generate
	a R_SPARC_NONE for the GOT slot if the symbol is also subject to
	old-style GOT relocations.
ld/
	* testsuite/ld-sparc/sparc.exp: Add test for mixed GOTDATA/GOT relocs.
	* testsuite/ld-sparc/gotop-hidden.c: New file.
	* testsuite/ld-sparc/got-hidden32.s: Likewise.
	* testsuite/ld-sparc/got-hidden64.s: Likewise.

		   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.
