Any sane compiler recognizes and removes dead code when it's as obvious as this (most do when it's less obvious). In fact, even code like #define HAVE_OPENSSL 0 if (HAVE_OPENSSL && some_other_condition) do_fun_things(); would be left out entirely. If do_fun_things() is static and called only from that point (or within blocks like this), it too will be removed.While that's most likely very true, is there a reason to make the compiler do it (just because it should) instead of the preprocessor (because you tell it)? I'm not by any means saying you're wrong, but I do (at least) think using the preprocessor #if/#else makes the code more readable/easier to understand rather than just leaving it out there for the compiler to do.
Perhaps, but considering that of the four patched blocks two were "return within ifdef" and two others just moved the #ifdef to above a comment, the patch is a no-op for the compiled code with the exception of moving that 'int tmp' outside it. I was just commenting since you didn't seem to be aware of it (no comments in the patch message about readability).
Of course, whatever's best.
Naturally. I'd say that 'int tmp' swings the balance. I'd probably apply it, after removing the blocks moving the #ifdefs anyways. -- Andreas Ericsson andreas.ericsson () op5 se OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 _______________________________________________ Sent through the nmap-dev mailing list http://cgi.insecure.org/mailman/listinfo/nmap-dev
