Jordan Rose 598654b4db Support for dumping current PrettyStackTrace on SIGINFO (Ctrl-T) ... Support SIGINFO (and SIGUSR1 for POSIX purposes) to tell what long-running jobs are doing, as inspired by BSD tools (including on macOS), by dumping the current PrettyStackTrace. This adds a new kind of signal handler for non-fatal "info" signals, similar to the "interrupt" handler that already exists for SIGINT (Ctrl-C). It then uses that handler to update a "generation count" managed by the PrettyStackTrace infrastructure, which is then checked whenever a PrettyStackTraceEntry is pushed or popped on each thread. If the generation has changed---i.e. if the user has pressed Ctrl-T---the stack trace is dumped, though unfortunately it can't include the deepest entry because that one is currently being constructed/destructed. https://reviews.llvm.org/D63750 llvm-svn: 365911		2019-07-12 16:05:09 +00:00
