* * dcrt0.cc (init_windows_system_directory): Record system_wow64_directoryChristopher Faylor2011-12-138-43/+95
| | | | | | | | | | | | | | | | | | | | | | | information. * exceptions.cc (_cygtls::inside_kernel): Modernize comment. Consider executing a DLL from the Wow64 directory as being "in the kernel". (_cygtls::call_signal_handler): For now, only deal with main_tls signals if main_tls is known to be executing in the cygwin DLL. To more closely emulate linux, consider the operation to be restartable if not executing in the main thread. * globals.cc (windows_system_directory): Remove NO_COPY. (windows_system_directory_length): Ditto. (system_wow64_directory): New variable. (system_wow64_directory_length): Ditto. * select.cc (cygwin_select): Don't issue a EINTR on non-main threads since that seems to be what Linux does. Add missing break to signal case/switch. (select_stuff::wait): Don't issue a EINTR on non-main threads since that seems to be what Linux does. Remove now-unneeded accommodation for WAIT_IO_COMPLETION. Add a comment. * sigproc.h (cygwait): Ditto. Don't return if signal_received noticed and it's not the main thread. * signal.cc (sigprocmask): Add standard syscall debug stuff. * thread.cc (pthread_sigmask): Ditto.
