Peter Maydell b10089a14c linux-user: Don't call gdb_handlesig() before queue_signal() The CPU main-loop routines for linux-user generally call gdb_handlesig() when they're about to queue a SIGTRAP signal. This is wrong, because queue_signal() will cause us to pend a signal, and process_pending_signals() will then call gdb_handlesig() itself. So the effect is that we notify gdb of the SIGTRAP, and then if gdb says "OK, continue with signal X" we will incorrectly notify gdb of the signal X as well. We don't do this double-notify for anything else, only SIGTRAP. Remove this unnecessary and incorrect code from all the targets except for nios2 (whose main loop is doing something different and broken, and will be handled in a separate patch). This bug only manifests if the user responds to the reported SIGTRAP using "signal SIGFOO" rather than "continue"; since the latter is the overwhelmingly common thing to do after a breakpoint most people won't have hit this.
