Tom de Vries 1001055e35 [gdb/testsuite] Fix gdb.dwarf2/enum-type-c++.exp with clang
When running test-case gdb.dwarf2/enum-type-c++.exp with clang, we get:
...
FAIL: gdb.dwarf2/enum-type-c++.exp: val1 has a parent
FAIL: gdb.dwarf2/enum-type-c++.exp: print ns::A::val1
FAIL: gdb.dwarf2/enum-type-c++.exp: val2 has correct parent
FAIL: gdb.dwarf2/enum-type-c++.exp: print ns::ec::val2
...

The problem is that the debug info produced by clang does not contain any
references to enumerators val1 and val2, or the corresponding enumeration
types.

Instead, the variables u1 and u2 are considered to be simply of type int:
...
 <1><fb>: Abbrev Number: 2 (DW_TAG_variable)
    <fc>   DW_AT_name        : u1
    <fd>   DW_AT_type        : <0x106>
    <101>   DW_AT_external    : 1
    <103>   DW_AT_location    : (DW_OP_addrx <0>)
 <1><106>: Abbrev Number: 3 (DW_TAG_base_type)
    <107>   DW_AT_name        : int
    <108>   DW_AT_encoding    : 5       (signed)
    <109>   DW_AT_byte_size   : 4
 <1><10a>: Abbrev Number: 2 (DW_TAG_variable)
    <10b>   DW_AT_name        : u2
    <10c>   DW_AT_type        : <0x106>
    <110>   DW_AT_external    : 1
    <112>   DW_AT_location    : (DW_OP_addrx <0x1>)
...

Fix this by checking whether val1 and val2 are present in the cooked index
before checking whether they have the correct parent.

This cannot be expressed efficiently with gdb_test_lines, so factor out
gdb_get_lines and use that instead.

The test-case still calls "maint print objfiles" twice, but the first time is
for have_index.  We should probably use a gdb_caching_proc for this.

Tested on aarch64-linux.

		   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.
