Other remote 30 protocols, if they use a different numbering, should make sure to 31 translate appropriately. 32 33 Since these numbers have actually made it out into other software 34 (stubs, etc.), you mustn't disturb the assigned numbering. If you 35 need to add new signals here, add them to the end of the explicitly 36 numbered signals, at the comment marker. Add them unconditionally, 37 not within any #if or #ifdef. 38 39 This is based strongly on Unix/POSIX signals for several reasons: 40 (1) This set of signals represents a widely-accepted attempt to 41 represent events of this sort in a portable fashion, (2) we want a 42 signal to make it from wait to child_wait to the user intact, (3) many 43 remote protocols use a similar encoding. However, it is 44 recognized that this set of signals has limitations (such as not 45 distinguishing between various kinds of SIGSEGV, or not 46 distinguishing hitting a breakpoint from finishing a single step). 47 So in the future we may get around this either by adding additional 48 signals for breakpoint, single-step, etc., or by adding signal 49 codes; the latter seems more in the spirit of what BSD, System V, 50 etc. are doing to address these issues. */ 51 52 /* For an explanation of what each signal means, see 53 signals.c. */ 54 55 enum target_signal 56 { 57 /* Used some places (e.g. stop_signal) to record the concept that 58 there is no signal. */ 59 TARGET_SIGNAL_0 = 0, 60 TARGET_SIGNAL_FIRST = 0, 61 TARGET_SIGNAL_HUP = 1, 62 TARGET_SIGNAL_INT = 2, 63 TARGET_SIGNAL_QUIT = 3, 64 TARGET_SIGNAL_ILL = 4, 65 TARGET_SIGNAL_TRAP = 5, 66 TARGET_SIGNAL_ABRT = 6, 67 TARGET_SIGNAL_EMT = 7, 68 TARGET_SIGNAL_FPE = 8, 69 TARGET_SIGNAL_KILL = 9, 70 TARGET_SIGNAL_BUS = 10, 71 TARGET_SIGNAL_SEGV = 11, 72 TARGET_SIGNAL_SYS = 12, 73 TARGET_SIGNAL_PIPE = 13, 74 TARGET_SIGNAL_ALRM = 14, 75 TARGET_SIGNAL_TERM = 15, 76 TARGET_SIGNAL_URG = 16, 77 TARGET_SIGNAL_STOP = 17, 78 TARGET_SIGNAL_TSTP = 18, 79 TARGET_SIGNAL_CONT = 19, 80 TARGET_SIGNAL_CHLD = 20, 81 TARGET_SIGNAL_TTIN = 21, 82 TARGET_SIGNAL_TTOU = 22, 83 TARGET_SIGNAL_IO = 23, 84 TARGET_SIGNAL_XCPU = 24, 85 TARGET_SIGNAL_XFSZ = 25, 86 TARGET_SIGNAL_VTALRM = 26, 87 TARGET_SIGNAL_PROF = 27, 88 TARGET_SIGNAL_WINCH = 28, 89 TARGET_SIGNAL_LOST = 29, 90 TARGET_SIGNAL_USR1 = 30, 91 TARGET_SIGNAL_USR2 = 31, 92 TARGET_SIGNAL_PWR = 32, 93 /* Similar to SIGIO.
