Modified Files: src/sys/kern: kern_sig.c kern_syscall.c src/sys/sys: ptrace.h siginfo.h Log Message: Ship with syscall information with SIGTRAP TRAP_SCE/TRAP_SCX for tracers Expand siginfo_t (struct size not changed) to new values for SIGTRAP TRAP_SCE/TRAP_SCX events. - si_sysnum -- syscall number (int) - si_retval -- return value (2 x int) - si_error -- error code (int) - si_args -- syscall arguments (8 x uint64_t) TRAP_SCE delivers si_sysnum and si_args. TRAP_SCX delivers si_sysnum, si_retval, si_error and si_args. Users: debuggers (like GDB) and syscall tracers (like strace, truss). This MI interface is similar to the Linux kernel proposal of PTRACE_GET_SYSCALL_INFO by the strace developer team.
