It is also the numbering of the GDB remote protocol. Other remote protocols, if they use a different numbering, should make sure to translate appropriately. Since these numbers have actually made it out into other software (stubs, etc.), you mustn't disturb the assigned numbering. If you need to add new signals here, add them to the end of the explicitly numbered signals. This is based strongly on Unix/POSIX signals for several reasons: (1) This set of signals represents a widely-accepted attempt to represent events of this sort in a portable fashion, (2) we want a signal to make it from wait to child_wait to the user intact, (3) many remote protocols use a similar encoding. However, it is recognized that this set of signals has limitations (such as not distinguishing between various kinds of SIGSEGV, or not distinguishing hitting a breakpoint from finishing a single step). So in the future we may get around this either by adding additional signals for breakpoint, single-step, etc., or by adding signal codes; the latter seems more in the spirit of what BSD, System V, etc. are doing to address these issues. */ /* For an explanation of what each signal means, see target_signal_to_string. */ enum target_signal { /* Used some places (e.g. stop_signal) to record the concept that there is no signal. */ TARGET_SIGNAL_0 = 0, TARGET_SIGNAL_FIRST = 0, TARGET_SIGNAL_HUP = 1, TARGET_SIGNAL_INT = 2, TARGET_SIGNAL_QUIT = 3, TARGET_SIGNAL_ILL = 4, TARGET_SIGNAL_TRAP = 5, TARGET_SIGNAL_ABRT = 6, TARGET_SIGNAL_EMT = 7, TARGET_SIGNAL_FPE = 8, TARGET_SIGNAL_KILL = 9, TARGET_SIGNAL_BUS = 10, TARGET_SIGNAL_SEGV = 11, TARGET_SIGNAL_SYS = 12, TARGET_SIGNAL_PIPE = 13, TARGET_SIGNAL_ALRM = 14, TARGET_SIGNAL_TERM = 15, TARGET_SIGNAL_URG = 16, TARGET_SIGNAL_STOP = 17, TARGET_SIGNAL_TSTP = 18, TARGET_SIGNAL_CONT = 19, TARGET_SIGNAL_CHLD = 20, TARGET_SIGNAL_TTIN = 21, TARGET_SIGNAL_TTOU = 22, TARGET_SIGNAL_IO = 23, TARGET_SIGNAL_XCPU = 24, TARGET_SIGNAL_XFSZ = 25, TARGET_SIGNAL_VTALRM = 26, TARGET_SIGNAL_PROF = 27, TARGET_SIGNAL_WINCH = 28, TARGET_SIGNAL_LOST = 29, TARGET_SIGNAL_USR1 = 30, TARGET_SIGNAL_USR2 = 31, TARGET_SIGNAL_PWR = 32, /* Similar to SIGIO.
