Ali Tamur a084a2a6a1 DWARF 5 support: Handle dwo_id
* DW_UT_skeleton and DW_UT_split_compile compilation units have dwo ids
to match the compilation unit in the skeleton and .dwo files. The dwo_id is
in the header.

Tested with CC=/usr/bin/gcc (version 8.3.0) against master branch (also with
-gsplit-dwarf and -gdwarf-4 flags) and there was no increase in the set of
tests that fails.

This is part of an effort to support DWARF 5 in gdb.

gdb/ChangeLog:

        * dwarf2read.c (comp_unit_head): Update comment.
        (dwarf2_dwo_name): New function declaration.
        (dwarf_unit_type_name): New function declaration.
        (read_comp_unit_head): Add support for new compilation units,
        DW_UT_partial, DW_UT_skeleton, DW_UT_split_compile, DW_UT_split_type.
        Particularly, DW_UT_skeleton and DW_UT_split_compile have dwo_id
        (currently named as "signature") in their header. Also clarify error
        messages.
        (lookup_dwo_id): New function. Returns the dwo id of the given
        compile unit.
        (lookup_dwo_unit): Use the new lookup_dwo_id function.
        (init_cutu_and_read_dies): Use the new dwarf2_dwo_name and lookup_dwo_id
        functions.
        (create_dwo_cu_reader): Use the added lookup_dwo_id function.
        (dwarf2_dwo_name): Get the dwo name if present.
        (dwarf_unit_type_name): Convert DW_UT_* types to string for diagnostic
        purposes.

		   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.
