3078 | This function must be neutral to the CASE_SENSITIVITY setting as the user |
3079 | may choose it during later lookup. Therefore this function always sorts | |
3080 | primarily case-insensitively and secondarily case-sensitively. | |

3082 | Here are some examples of why using strcmp to sort is a bad idea: |
3083 | ||
3084 | Whitespace example: | |
3085 | ||
3086 | Say your partial symtab contains: "foo<char *>", "goo". Then, if | |
3087 | we try to do a search for "foo<char*>", strcmp will locate this | |
3088 | after "foo<char *>" and before "goo". Then lookup_partial_symbol | |
3089 | will start looking at strings beginning with "goo", and will never | |
3090 | see the correct match of "foo<char *>". | |
3091 | ||
3092 | Parenthesis example: | |
3093 | ||
3094 | In practice, this is less like to be an issue, but I'll give it a | |
3095 | shot. Let's assume that '$' is a legitimate character to occur in | |
3096 | symbols. (Which may well even be the case on some systems.) Then | |
3097 | say that the partial symbol table contains "foo$" and "foo(int)". | |
3098 | strcmp will put them in this order, since '$' < '('. Now, if the | |
3099 | user searches for "foo", then strcmp will sort "foo" before "foo$". | |
3100 | Then lookup_partial_symbol will notice that strcmp_iw("foo$", | |
3101 | "foo") is false, so it won't proceed to the actual match of | |
3102 | "foo(int)" with "foo". */ | |
