binutils-gdb modified for the FreeChainXenon project

A subsequent patch makes use of non-trivial types in struct so_list.
This trips on the fact that svr4_copy_library_list uses memcpy to copy
so_list objects:
so_list *newobj = new so_list;
memcpy (newobj, src, sizeof (struct so_list));
solib-svr4 maintains lists of so_list objects in its own internal data
structures. When requested to return a list of so_list objects (through
target_so_ops::current_sos), it duplicates the internal so_list lists,
using memcpy. When changing so_list to make it non-trivial, we would
need to replace this use of memcpy somehow. That would mean making
so_list copyable, with all the complexity that entails, just to satisfy
this internal usage of solib-svr4 (and solib-rocm, which does the same).
Change solib-svr4 to use its own data type for its internal lists. The
use of so_list is a bit overkill anyway, as most fields of so_list are
irrelevant for this internal use.
- Introduce svr4_so, which contains just an std::string for the name
and a unique_ptr for the lm_info.
- Change the internal so_list lists to be std::vector<svr4_so>. Vector
seems like a good choice for this, we don't need to insert/remove
elements in the middle of these internal lists.
- Remove svr4_free_library_list, free_solib_lists and ~svr4_info, as
everything is managed automatically now.
- Replace svr4_copy_library_list (which duplicated internal lists in
order to return them to the core) with so_list_from_svr4_sos, which
creates an so_list list from a vector of svr4_so.
- Generalize svr4_same a bit, because find_debug_base_for_solib now
needs to compare an so_list and an svr4_so to see if they are the
same.

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.
