whether or not to send signal_arrived.
* shm.cc (client_request_shm::client_request_shm): Call
ipc_set_proc_info with bool parameter set to true to not send
signal_arrived.
* configure.host (sys_dir, newlib_cflags): Set sys_dir to tirtos and use
-D__DYNAMIC_REENT__ and -DMALLOC_PROVIDED compiler options for TIRTOS
target.
* libc/stdio/local.h (_STDIO_CLOSE_PER_REENT_STD_STREAMS): Change #ifdef
to not define this macro when __tirtos__ is defined.
* libc/sys/tirtos : Add support for TIRTOS.
* libc/sys/tirtos/Makefile.am, libc/sys/tirtos/lock.c: New files.
* libc/sys/tirtos/configure.in, libc/sys/tirtos/include/sys/lock.h: Ditto.
* exceptions.cc (_cygtls::signal_debugger): Reorganize to avoid contacting the
debugger if we have already done so via the exception handler. Eliminate need
for goto. Remove an ifdef in favor of just allocating a larger buffer.
* exception.h (exception_list): Typedef as void on x86_64.
(exception::handler_installed): Remove.
(exception::handle_while_being_debugged): Remove.
(exception::myfault_handle): Declare for x86_64.
(exception::handle): Declare as ordinary exception handler on x86_64
as well.
(exception::exception): Drop previous code (again). Install
exception::handle as SEH handler.
(exception::install_myfault_handler): New x86_64-only method to
install exception::myfault_handle as VEH handler. Explain why.
(exception::~exception): For x86_64, define frame end label (again).
* exceptions.cc (CYG_EXC_CONTINUE_EXECUTION): Drop definition.
(CYG_EXC_CONTINUE_SEARCH): Ditto.
(exception::myfault_handle): New x86_64-only method, VEH handler to
handle myfault exceptions.
(exception::handle): Define as ordinary exception handler on x86_64
as well. Use ExceptionContinueExecution and ExceptionContinueSearch
throughout instead of deleted Cygwin macros. Don't handle myfault
exceptions on x86_64.
(setjmp/x86_64): Drop storing ExceptionList pointer in jmp_buf->Frame.
Drop comment. Store likely frame in rdx. Jump to __setjmpex.
(__setjmpex): New function providing setjmp functionality. Fetch
jmp_buf->Frame from rdx, like MSVCRT setjmpex.
(__sjfault/x86_64): Store rdx content in jmp_buf->Frame.
(__ljfault/x86_64): Don't restore ExceptionList pointer.
(longjmp/x86_64): Ditto.
