Instead of checking the return value of do_signal() we can just do the work (raise SIGTRAP and clear SR.T1) directly in handle_signal(), when setting the sigframe up. Simplifies the assembler glue and is closer to the way we do it on other targets. Note that do_delayed_trace does *not* disappear; it's still needed to deal with single-stepping through syscall, since 68040 doesn't raise the trace exception at all if the trap exception is pending. We hit it after returning from sys_...() if TIF_DELAYED_TRACE is set; all that has changed is that we don't reuse it for "single-step into the handler" codepath. As the result, do_signal() doesn't need to return anything anymore. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> |
