[dev.cc] runtime: convert Solaris port to Go Memory management was consolitated with the BSD ports, since it was almost identical. Assembly thunks are gone, being replaced by the new //go:linkname feature. This change supersedes CL 138390043 (runtime: convert solaris netpoll to Go), which was previously reviewed and tested. This change is only the first step, the port now builds, but doesn't run. Binaries fail to exec: ld.so.1: 6.out: fatal: 6.out: TLS requirement failure : TLS support is unavailable Killed This seems to happen because binaries don't link with libc.so anymore. We will have to solve that in a different CL. Also this change is just a rough translation of the original C code, cleanup will come in a different CL. [This CL is part of the removal of C code from package runtime. See golang.org/s/dev.cc for an overview.] LGTM=rsc R=rsc, dave CC=golang-codereviews, iant, khr, minux, r, rlh https://golang.org/cl/174960043

runtime: if we don't handle a signal on a non-Go thread, raise it In the past badsignal would crash the program. In https://golang.org/cl/10757044 badsignal was changed to call sigsend, to fix issue #3250. The effect of this was that when a non-Go thread received a signal, and os/signal.Notify was not being used to check for occurrences of the signal, the signal was ignored. This changes the code so that if os/signal.Notify is not being used, then the signal handler is reset to what it was, and the signal is raised again. This lets non-Go threads handle the signal as they wish. In particular, it means that a segmentation violation in a non-Go thread will ordinarily crash the process, as it should. Fixes #10139. Update #11794.
