Forward signals to signal handlers installed before Go installs its own, under certain circumstances. In particular, as iant@ suggests, signals are forwarded iff: (1) a non-SIG_DFL signal handler existed before Go, and (2) signal is synchronous (i.e., one of SIGSEGV, SIGBUS, SIGFPE), and (3a) signal occured on a non-Go thread, or (3b) signal occurred on a Go thread but in CGo code. Supported only on Linux, for now. Change-Id: I403219ee47b26cf65da819fb86cf1ec04d3e25f5 Reviewed-on: https://go-review.googlesource.com/8712 Reviewed-by: Ian Lance Taylor <iant@golang.org>
