Other remote 25 protocols, if they use a different numbering, should make sure to 26 translate appropriately. 27 28 Since these numbers have actually made it out into other software 29 (stubs, etc.), you mustn't disturb the assigned numbering. If you 30 need to add new signals here, add them to the end of the explicitly 31 numbered signals, at the comment marker. Add them unconditionally, 32 not within any #if or #ifdef. 33 34 This is based strongly on Unix/POSIX signals for several reasons: 35 (1) This set of signals represents a widely-accepted attempt to 36 represent events of this sort in a portable fashion, (2) we want a 37 signal to make it from wait to child_wait to the user intact, (3) many 38 remote protocols use a similar encoding. However, it is 39 recognized that this set of signals has limitations (such as not 40 distinguishing between various kinds of SIGSEGV, or not 41 distinguishing hitting a breakpoint from finishing a single step). 42 So in the future we may get around this either by adding additional 43 signals for breakpoint, single-step, etc., or by adding signal 44 codes; the latter seems more in the spirit of what BSD, System V, 45 etc. are doing to address these issues. */ 46 47 /* For an explanation of what each signal means, see 48 gdb_signal_to_string. */ 49 50 enum gdb_signal 51 { 52 #define SET(symbol, constant, name, string) \ 53 symbol = constant, 54 #include "gdb/signals.def" 55 #undef SET 56 }; 57 58 #endif /* #ifndef GDB_SIGNALS_H */ 59
