So I decided to prepare a patch to fix this, because there are *many* places with unused variables. However, before continuing to prepare this patch, I would like what you think about enabling -Wunused-variable by default in the building. I am not sure I can foresee something wrong with it, but maybe others have some different opinions. Thanks, -- Sergio P.S.: I couldn't find any real discussion about this on the list archives, but please excuse me if this has been already discussed. ^ permalink raw reply [flat|nested] 17+ messages in thread

There are more useful -Wunused* options, GDB uses now: -Wno-unused -Wunused-value -Wunused-function IIRC the counterargument for -Wunused-variable was that GDB contains various #if-compiled code where is a nightmare to get the code right with matching #if-clauses also for the variables being used by various #if-compiled code chunks. I could not find that mail now in the time I gave to it. I believe more -Wunused* would be worth it, maybe the mail was before Joel started to disable -Werror for releases so that claim about problematic #if-clauses is no longer valid.

In general, you will encounter a lot of resistance to increasing warning. For example, try to add -Wall -Wextra -Wconversion -Wstrict-overflow to CFLAGS or CXXFLAGS on some project. Some even refute the results even when they are valid findings. For example, when static analysis warned the kernel's sys_prctl was comparing an unsigned value against less than zero, Jesper Juhl offered a patch to clean up the code. Linus Torvalds howled “No, you don't do this... GCC is crap.” For the full discussion, see "[PATCH] Don't compare unsigned variable for <0 in sys_prctl()" (http://linux.derkeiler.com/Mailing-Lists/Kernel/2006-11/msg08325.html) from the Linux Kernel mailing list. I live and die by GCC's static analysis capabilities. I've got stuff that has been in the field for years and never taken a bug report or crashed. But I also validate all parameter in each function (C/C++ makes no guarantees on a call graph), I also check all return values, assert *everything* in debug builds (the best code is code that debugs itself), and write negative test cases. I could not care less about positive test cases since you could hire a kid from a third world country to copy/paste code that passes positive tests. If I got pwned as often as the l33t k3rn3l hAck3rz, I would consider finding a new profession. Worst, the tools are already available to find an fix most of the low hanging fruit. Arrogance and ignorance is a big problem in the community... Jeff ^ permalink raw reply [flat|nested] 17+ messages in thread

That sort of thing obscures whether the variable later dies. I'd say that the best approach would be to make the declarations conditional in the same way that the uses are. If there are a lot of problem cases with this approach, or if it makes the code too ugly, then maybe it would be better just not to use this flag.

Ok, that makes sense to me. Since there are tons of places with unused variables in the code, I will take some time to look and convert the proper places to use this solution.

That IMHO just asks to refrain from interspersing function bodies with preprocessor conditionals. Lots if not all conditional stuff can be factored out to headers or definitions elsewhere. Linux the kernel for one has had such a policy for years now. Example. Do not write this: int target_frobnicate (int count); #ifdef TARGET_NEEDS_HARD_FROBNICATION int target_frobnicate_harder (int count, int status); #endif int handle_frobnication (int count) { int status; int i; status = target_frobnicate (count); #ifdef TARGET_NEEDS_HARD_FROBNICATION for (i = 0; i < count; i++) status = target_frobnicate_harder (i, status); #endif return status; } Instead write this: int target_frobnicate (int count); #ifdef TARGET_NEEDS_HARD_FROBNICATION int target_frobnicate_harder (int count, int status); #define target_needs_hard_frobnication 1 #else #define target_needs_hard_frobnication 0 endif int handle_frobnication (int count) { int status; int i; status = target_frobnicate (count); if (target_needs_hard_frobnication) for (i = 0; i < count; i++) status = target_frobnicate_harder (i, status); return status; } -- "i" is now live in all cases and also IMHO handle_frobnication is more readable.

It also requires an unconditional declaration and definition of target_frobnicate_harder.

Yes, but do you see at as advantage or disadvantage? Please note that my example can be easily adapted to a three-way choice where the value of target_frobnicate_harder can only be determined at the run time, e.g.: #ifdef TARGET_NEEDS_HARD_FROBNICATION #define target_needs_hard_frobnication 1 #else if defined TARGET_SUPPORTS_HARD_FROBNICATION int target_needs_hard_frobnication; #else #define target_needs_hard_frobnication 0 endif and then you still have all the conditional bits localised here and don't have to modify handle_frobnication at at all. :) Maciej ^ permalink raw reply [flat|nested] 17+ messages in thread

The declaration should be moved outside the conditional, I've overlooked that, sorry. If target_frobnicate_harder is external then the prototype will be in a header anyway. And such an unconditional declaration is actually good for conditional pieces that are rarely enabled -- people making bulk changes will still receive the usual diagnostics about this function's argument type compatibility, etc. even if this piece of code is actually not used for the configuration they chose, as long as this source file is compiled at all. Then you don't actually need a definition, because the call will be optimised away (together with the whole enclosing "if (0)" block) by the compiler. There's nothing wrong with having a declaration and no definition for an entity that's never eventually used. Maciej ^ permalink raw reply [flat|nested] 17+ messages in thread

GCC eliminates the unreachable block of an "if (0)" even without optimization. Many other compilers don't. It is an ongoing source of complications for getting compilers other than GCC to build the linux kernel which uses this approach extensively. If the project cares about being able to build with compilers other than GCC, then it should consider this approach as carefully as it considers using any other GCC extension.

That sounds silly, I didn't know that. In this case a "static inline" dummy function would have to be provided indeed that makes the solution a bit less elegant then I would like it to be. Still probably better than a maze of #ifdefs scattered throughout code, but YMMV. Maciej ^ permalink raw reply [flat|nested] 17+ messages in thread
