Christian Biesinger 626ca2c06f Replace solib_global_lookup with gdbarch_iterate_over_objfiles_in_search_order
All implementations of either function use it for the same purpose (except
Darwin, which is a no-op): to prefer a symbol in the current objfile over
symbols with the same name in other objfiles. There does not seem to be a
reason to have both mechanisms for that purpose.

gdb/ChangeLog:

2019-09-20  Christian Biesinger  <cbiesinger@google.com>

	* solib-darwin.c (darwin_lookup_lib_symbol): Remove.
	(_initialize_darwin_solib): Don't set
	darwin_so_ops.lookup_lib_global_symbol.
	* solib-svr4.c (set_solib_svr4_fetch_link_map_offsets): Call
	set_gdbarch_iterate_over_objfiles_in_search_order.
	(elf_lookup_lib_symbol): Rename to...
	(svr4_iterate_over_objfiles_in_search_order): this, and update
	to iterate semantics.
	(_initialize_svr4_solib): Don't set lookup_lib_global_symbol.
	* solib.c (solib_global_lookup): Remove.
	* solist.h (struct target_so_ops): Remove lookup_lib_global_symbol.
	(solib_global_lookup): Remove.
	* symtab.c (lookup_global_or_static_symbol): Remove call to
	solib_global_lookup.

		   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.
