target_is_non_stop_p and sync targets
gdb.base/maint-target-async-off.exp fails if you test against gdbserver with "maint set target-non-stop on" forced. (gdb) run Starting program: build/gdb/testsuite/outputs/gdb.base/maint-target-async-off/maint-target-async-off Breakpoint 1, main () at src/gdb/testsuite/gdb.base/maint-target-async-off.c:21 21 return 0; (gdb) FAIL: gdb.base/maint-target-async-off.exp: continue until exit (timeout) Above, GDB just stopped listening to stdin. Basically, GDB assumes that a target working in non-stop mode operation also supports async mode; it's a requirement. GDB misbehaves badly otherwise, and even hits failed assertions. Fix this by making target_is_non_stop_p return false if async is off. gdb/ChangeLog: * target.c (target_always_non_stop_p): Also check whether the target can async.
