Pedro Alves 96e9210fd6 C++: dlsym casts in gdb/linux-thread-db.c and gdb/gdbserver/thread-db.c
Implicit void * -> function pointer conversion doesn't work in C++, so
in C++, we need to cast the result of dlsym.  This adds a few typedefs
and macros that make this easy.  GDBserver's version already had the
CHK macro, so I added it to GDB too.

Tested on x86_64 Fedora 20, native and gdbserver.

gdb/gdbserver/ChangeLog:
2015-08-04  Pedro Alves  <palves@redhat.com>

	* thread-db.c (struct thread_db): Use new typedefs.
	(try_thread_db_load_1): Define local TDB_DLSYM macro and use it in
	CHK calls.
	(disable_thread_event_reporting): Cast result of dlsym to
	destination function pointer type.
	(thread_db_mourn): Use td_ta_delete_ftype.

gdb/ChangeLog:
2015-08-04  Pedro Alves  <palves@redhat.com>

	* nat/gdb_thread_db.h (td_init_ftype, td_ta_new_ftype)
	(td_ta_map_lwp2thr_ftype, td_ta_thr_iter_ftype)
	(td_ta_event_addr_ftype, td_ta_set_event_ftype)
	(td_ta_clear_event_ftype, td_ta_event_getmsg_ftype)
	(td_thr_validate_ftype, td_thr_get_info_ftype)
	(td_thr_event_enable_ftype, td_thr_tls_get_addr_ftype)
	(td_thr_tlsbase_ftype, td_symbol_list_ftype, td_ta_delete_ftype):
	New typedefs.
	* linux-thread-db.c (struct thread_db_info): Use new typedefs.
	(try_thread_db_load_1): Define TDB_VERBOSE_DLSYM, TDB_DLSYM , CHK
	local macros and use them instead of verbose_dlsym and dlsym
	calls.

		   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.
