Peter Foley 0008bdea02 Refactor to avoid nonnull checks on "this" pointer.
G++ 6.0 asserts that the "this" pointer is non-null for member
functions.
Refactor methods that check if "this" is non-null to resolve this.

winsup/cygwin/ChangeLog:
external.cc (cygwin_internal): Check for a null pinfo before calling
cmdline.
fhandler_dsp.cc (Audio::blockSize): Make static.
fhandler_dsp.cc (Audio_in): add default_buf_info.
fhandler_dsp.cc (Audio_out): Ditto.
fhandler_dsp.cc (Audio_out::buf_info): Refactor method to call
default_buf_info if dev_ is null.
fhandler_dsp.cc (Audio_in::buf_info): Ditto.
fhandler_dsp.cc (fhandler_dev_dsp::_ioctl): Call Audio_out::default_buf_info if audio_out_ is null.
fhandler_dsp.cc (fhandler_dev_dsp::_ioctl): Call Audio_in::default_buf_info if audio_in_ is null.
fhandler_process.cc (format_process_fd): Check if pinfo is null.
fhandler_process.cc (format_process_root): Ditto.
fhandler_process.cc (format_process_cwd): Ditto.
fhandler_process.cc (format_process_cmdline): Ditto.
signal.cc (tty_min::kill_pgrp): Ditto.
signal.cc (_pinfo::kill0): Ditto.
sigproc.cc (pid_exists): Ditto.
sigproc.cc (remove_proc): Ditto.
times.cc (clock_gettime): Ditto.
times.cc (clock_getcpuclockid): Ditto.
path.cc (cwdstuff::override_win32_cwd): Check if old_cwd is null.
path.cc (fcwd_access_t::Free): Factor null check of "this" out to
caller(s).
pinfo.cc (_pinfo::exists): Ditto.
pinfo.cc (_pinfo::fd): Ditto.
pinfo.cc (_pinfo::fds): Ditto.
pinfo.cc (_pinfo::root): Ditto.
pinfo.cc (_pinfo::cwd): Ditto.
pinfo.cc (_pinfo::cmdline): Ditto.
signal.cc (_pinfo::kill): Ditto.
pinfo.cc (_pinfo::commune_request): remove non-null check on "this", as
this method is only called from pinfo.cc after null checks
pinfo.cc (_pinfo::pipe_fhandler): remove non-null check on "this", as
this method is only called from pipe.cc (fhandler_pipe::open) after a null check.

README

		   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.
