Alan Modra 127e8e9f62 PR22394, hppa-linux-ld fails to emit dynamic relocations
gcc -mfast-indirect-calls emits a function pointer initialization
without a P% (plabel) modifier.  ld does not create the necessary
dynamic relocations for this to work.  It turns out that the problem
is caused by the non_got_ref symbol flag.  This flag is set for
non-pic by check_relocs to indicate that the symbol might need copy
relocations or dynamic relocations.  Later, the backend
adjust_dynamic_symbol clears the flag to indicate dynamic relocations
are needed, but leaves it set when copy relocations were created.  The
inversion in meaning is insane, but it's that way because the backend
adjust_dynamic_symbol function doesn't get to look at all symbols..
Anyway, the insanity works for non-function symbols.  However, the
flag is left set on any function symbol with a dynamic relocation.

This patch fixes the non_got_ref handling for function symbols, adds
-z nocopyreloc for hppa-elf, reports where textrel occurs, and expands
comments.  The check_relocs change just stops creation of dyn_relocs
we always threw away later.

	PR 22394
	* elf32-hppa.c (elf32_hppa_check_relocs): Don't create dyn_relocs
	for plabels when non-pic.
	(maybe_set_textrel): New function.
	(readonly_dynrelocs): Move and rewrite.
	(elf32_hppa_adjust_dynamic_symbol): Use it.  Don't create copy
	relocs when def_regular or -z nocopyreloc.  Handle non_got_ref
	for functions.  Expand non_got_ref comments.
	(elf32_hppa_size_dynamic_sections): Use maybe_set_textrel.

		   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.
