2940 strcmp (and unlike strcmp_iw), it returns negative if STRING1 <
2941 STRING2, 0 if STRING2 = STRING2, and positive if STRING1 > STRING2
2942 according to that ordering.
2944 If a list is sorted according to this function and if you want to
2945 find names in the list that match some fixed NAME according to
2946 strcmp_iw(LIST_ELT, NAME), then the place to start looking is right
2947 where this function would put NAME.
2949 This function must be neutral to the CASE_SENSITIVITY setting as the user
2950 may choose it during later lookup. Therefore this function always sorts
2951 primarily case-insensitively and secondarily case-sensitively.
2953 Here are some examples of why using strcmp to sort is a bad idea:
2957 Say your partial symtab contains: "foo<char *>", "goo". Then, if
2958 we try to do a search for "foo<char*>", strcmp will locate this
2959 after "foo<char *>" and before "goo". Then lookup_partial_symbol
2960 will start looking at strings beginning with "goo", and will never
2961 see the correct match of "foo<char *>".
2963 Parenthesis example:
2965 In practice, this is less like to be an issue, but I'll give it a
2966 shot. Let's assume that '$' is a legitimate character to occur in
2967 symbols. (Which may well even be the case on some systems.) Then
2968 say that the partial symbol table contains "foo$" and "foo(int)".
2969 strcmp will put them in this order, since '$' < '('. Now, if the
2970 user searches for "foo", then strcmp will sort "foo" before "foo$".
2971 Then lookup_partial_symbol will notice that strcmp_iw("foo$",
2972 "foo") is false, so it won't proceed to the actual match of
2973 "foo(int)" with "foo". */
