3147 | /* This is like strcmp except that it ignores whitespace and treats |
3148 | '(' as the first non-NULL character in terms of ordering. Like | |
3149 | strcmp (and unlike strcmp_iw), it returns negative if STRING1 < | |
3150 | STRING2, 0 if STRING2 = STRING2, and positive if STRING1 > STRING2 | |
3151 | according to that ordering. | |
3152 | ||
3153 | If a list is sorted according to this function and if you want to | |
3154 | find names in the list that match some fixed NAME according to | |
3155 | strcmp_iw(LIST_ELT, NAME), then the place to start looking is right | |
3156 | where this function would put NAME. | |
3157 | ||
559a7a62 JK |
3158 | This function must be neutral to the CASE_SENSITIVITY setting as the user |
3159 | may choose it during later lookup. Therefore this function always sorts | |
3160 | primarily case-insensitively and secondarily case-sensitively. | |
3161 | ||
0fe19209 DC |
3162 | Here are some examples of why using strcmp to sort is a bad idea: |
3163 | ||
3164 | Whitespace example: | |
3165 | ||
3166 | Say your partial symtab contains: "foo<char *>", "goo". Then, if | |
3167 | we try to do a search for "foo<char*>", strcmp will locate this | |
3168 | after "foo<char *>" and before "goo". Then lookup_partial_symbol | |
3169 | will start looking at strings beginning with "goo", and will never | |
3170 | see the correct match of "foo<char *>". | |
3171 | ||
3172 | Parenthesis example: | |
3173 | ||
3174 | In practice, this is less like to be an issue, but I'll give it a | |
3175 | shot. Let's assume that '$' is a legitimate character to occur in | |
3176 | symbols. (Which may well even be the case on some systems.) Then | |
3177 | say that the partial symbol table contains "foo$" and "foo(int)". | |
3178 | strcmp will put them in this order, since '$' < '('. Now, if the | |
3179 | user searches for "foo", then strcmp will sort "foo" before "foo$". | |
3180 | Then lookup_partial_symbol will notice that strcmp_iw("foo$", | |
3181 | "foo") is false, so it won't proceed to the actual match of | |
3182 | "foo(int)" with "foo". */ | |
