Corinna Vinschen a54bc198b1 Implement correct RLIMIT_STACK handling
* miscfuncs.cc (struct pthread_wrapper_arg): Add member guardsize.
        (pthread_wrapper): Set thread stack guarantee according to guardsize.
        Tweak assembler code so that $rax/$eax is not required by GCC to
        prepare the wrapper_arg value.
        (CygwinCreateThread): Fix deadzone handling.  Drop setting a "POSIX"
        guardpage (aka page w/ PAGE_NOACCESS).  Always use Windows guard
        pages instead.  On post-XP systems (providing SetThreadStackGuarantee)
        always set up stack Windows like with reserved/commited areas and
        movable guard pages.  Only on XP set up stack fully commited if the
        guardpage size is not the default system guardpage size.
        Fill out pthread_wrapper_arg::guardsize.  Improve comments.
        * resource.cc: Implement RSTACK_LIMIT Linux-like.
        (DEFAULT_STACKSIZE): New macro.
        (DEFAULT_STACKGUARD): Ditto.
        (rlimit_stack_guard): New muto.
        (rlimit_stack): New global variable holding current RSTACK_LIMIT values.
        (__set_rlimit_stack): Set rlimit_stack under lock.
        (__get_rlimit_stack): Initialize rlimit_stack from executable header
        and return rlimit_stack values under lock.
        (get_rlimit_stack): Filtering function to return useful default
        stacksize from rlimit_stack.rlim_cur value.
        (getrlimit): Call __get_rlimit_stack in RLIMIT_STACK case.
        (setrlimit): Call __set_rlimit_stack in RLIMIT_STACK case.
        * thread.cc (pthread::create): Fetch default stacksize calling
        get_rlimit_stack.
        (pthread_attr::pthread_attr): Fetch default guardsize calling
        wincap.def_guard_page_size.
        (pthread_attr_getstacksize): Fetch default stacksize calling
        get_rlimit_stack.
        * thread.h (PTHREAD_DEFAULT_STACKSIZE): Remove.
        (PTHREAD_DEFAULT_GUARDSIZE): Remove.
        (get_rlimit_stack): Declare.

Corinna Vinschen 2cd7eb7f60 Fix original stack when running signal handler on alternate stack
* autoload.cc (SetThreadStackGuarantee): Import.

        called context.
        * exceptions.cc (exception::handle): Exit from process via signal_exit
        in case sig_send returns from handling a stack overflow SIGSEGV.
        Explain why.

        from another thread.
        (signal_exit): Fix argument list to reflect three-arg signal handler.
        In case we have to create a stackdump for a stack overflow condition,
        do so from a separate thread.  Explain why.
        (sigpacket::process): Don't run signal_exit on alternate stack.
        (altstack_wrapper): Wrapper function to do stack correction when
        calling the signal handler on an alternate stack to handle a stack
        overflow.  Make sure to have lots of comments.
        (_cygtls::call_signal_handler): Drop local context variable to reduce
        stack pressure.  Use this->context instead.  Change inline assembler
        to call altstack_wrapper.

Takashi Yano c846bca992 Fix OPOST for non-Cygwin pty slaves
* fhandler.h (class fhandler_base): Add virtual function
	get_io_handle_cyg() to get handle from which OPOST-processed output is
	read on PTY master.
	(class fhandler_pty_slave): Add variable output_handle_cyg to store a
	handle to which OPOST-processed output is written. Add two functions,
	i.e., set_output_handle_cyg() and get_output_handle_cyg(), regarding
	variable output_handle_cyg. Now, output_handle is used only by native
	windows program. The data before OPOST-processing is written to
	output_handle and OPOST-processing is applied in the master-side. For a
	cygwin process, OPOST-processing is applied in the slave-side, and the
	data after OPOST-processing is written to output_handle_cyg.
	(class fhandler_pty_master): Add two variables, i.e., io_handle_cyg and
	to_master_cyg, to store handles of a pipe through which OPOST-processed
	output passes. Add pty_master_fwd_thread and function
	pty_master_fwd_thread() for a thread which applies OPOST-processing
	and forwards data from io_handle to to_master_cyg. Add function
	get_io_handle_cyg() regarding variable io_handle_cyg. Now, the pipe
	between io_handle and to_master are used only by native windows program
	for applying OPOST-processing in the master-side. For a cygwin process,
	the pipe between io_handle_cyg and to_master_cyg is used for passing
	through the data which is applied OPOST-processing in the slave-side.
	* fhandler_tty.cc (struct pipe_reply): Add member to_master_cyg.
	(fhandler_pty_master::process_slave_output): Read slave output from
	io_handle_cyg rather than io_handle.
	(fhandler_pty_slave::fhandler_pty_salve): Initialize output_handle_cyg.
	(fhandler_pty_slave::open): Set output_handle_cyg by duplicating handle
	to_master_cyg on PTY master.
	(fhandler_pty_slave::close): Close handle output_handle_cyg.
	(fhandler_pty_slave::write): Write data to output_handle_cyg rather
	than output_handle.
	(fhandler_pty_slave::fch_close_handles): Close handle output_handle_cyg.
	(fhandler_pty_master::fhandler_pty_master): Initialize io_handle_cyg,
	to_master_cyg and master_fwd_thread.
	(fhandler_pty_master::cleanup): Clean up to_master_cyg as well.
	(fhandler_pty_master::close): Print to_master_cyg as well in debug
	message. Terminate master forwarding thread. Close handles
	to_master_cyg and io_handle_cyg.
	(fhandler_pty_master::ioctl): Use io_handle_cyg rather than to_master.
	(fhandler_pty_master::pty_master_thread): Add code for duplicating
	handle to_master_cyg.
	(fhandler_pty_master::pty_master_fwd_thread): New function for a thread
	to forward OPOST-processed data from io_handle to to_master_cyg.  This
	thread applies OPOST-processing to the output of native windows program.
	(::pty_master_fwd_thread): Ditto.
	(fhandler_pty_master::setup): Create a new pipe to pass thruegh OPOST-
	processed output. Create new thread to forward data from io_handle to
	to_master_cyg. Set handle to_master_cyg to tty. Print io_handle_cyg as
	well in debug message. Close handles io_handle_cyg and to_master_cyg in
	case of error.
	(fhandler_pty_master::fixup_after_fork): Set handle to_master_cyg to
	tty. Copy handle to_master_cyg from arch->to_master_cyg.
	(fhandler_pty_master::fixup_after_exec): Clean up to_master_cyg.
	* select.cc: Check handle returned by get_io_handle_cyg() rather than
	get_handle().
	* tty.h (class tty): Add variable _to_master_cyg to store a handle to
	which OPOST-processed data is written. Add two functions,
	to_master_cyg() and set_to_master_cyg(), regarding _to_master_cyg.

Selectively using -fomit-frame-pointer when -O is used doesn't make sense

exceptions.cc must be compiled with -fno-omit-frame-pointer on x86, as it uses
RtlCaptureContext, which requires a frame pointer.

Jon TURNEY 383ff5fc47 Try to make sure struct _mcontext is 16-byte aligned
On x86_64, RtlCaptureContext() uses fxsave to save FPU/MMX/SSE state.

fxsave requires that the destination address is 16-byte aligned, or it will
fault.

CONTEXT is already annotated __attribute__ ((aligned (16))), do the same with
struct _mcontext.

Rearrange ucontext_t so that it's struct _mcontext element is also correctly
aligned.
