2329 Here are some examples of why using strcmp to sort is a bad idea:
2333 Say your partial symtab contains: "foo<char *>", "goo". Then, if
2334 we try to do a search for "foo<char*>", strcmp will locate this
2335 after "foo<char *>" and before "goo". Then lookup_partial_symbol
2336 will start looking at strings beginning with "goo", and will never
2337 see the correct match of "foo<char *>".
2339 Parenthesis example:
2341 In practice, this is less like to be an issue, but I'll give it a
2342 shot. Let's assume that '$' is a legitimate character to occur in
2343 symbols. (Which may well even be the case on some systems.) Then
2344 say that the partial symbol table contains "foo$" and "foo(int)".
2345 strcmp will put them in this order, since '$' < '('. Now, if the
2346 user searches for "foo", then strcmp will sort "foo" before "foo$".
2347 Then lookup_partial_symbol will notice that strcmp_iw("foo$",
2348 "foo") is false, so it won't proceed to the actual match of
2349 "foo(int)" with "foo". */
