To avoid problems like the one fixed by Stephane Eranian in 3de29cab, now we'll got this instead: bench/sched-messaging.c:259: error: negative width in bit-field ‘<anonymous>’ bench/sched-messaging.c:261: error: negative width in bit-field ‘<anonymous>’ Which is rather cryptic, but is how BUILD_BUG_ON_ZERO works, so kernel hackers should be already used to this. With it in place found some problems, fixed by changing the affected variables to sensible types or changed some OPT_INTEGER to OPT_UINTEGER. Next csets will go thru converting each of the remaining OPT_ so that review can be made easier by grouping changes per type per patch.

Parsing an option from the command line with OPT_BOOLEAN on a bool data type would not work on a big-endian machine due to the manner in which the boolean was being cast into an int and incremented. For example, running 'perf probe --list' on a PowerPC machine would fail to properly set the list_events bool and would therefore print out the usage information and terminate. This patch makes OPT_BOOLEAN work as expected with a bool datatype. For cases where the original OPT_BOOLEAN was intentionally being used to increment an int each time it was passed in on the command line, this patch introduces OPT_INCR with the old behaviour of OPT_BOOLEAN (the verbose variable is currently the only such example of this). I have reviewed every use of OPT_BOOLEAN to verify that a true C99 bool was passed. Where integers were used, I verified that they were only being used for boolean logic and changed them to bools to ensure that they would not be mistakenly used as ints. The major exception was the verbose variable which now uses OPT_INCR instead of OPT_BOOLEAN. Signed-off-by: NIan Munsie <imunsie@au.ibm.com> Acked-by: NDavid S.

There is no predefined macro to create an option that can have a custom value or a default one if none is given. This patch provides a new helper OPT_CALLBACK_DEFAULT() which defines such kind of option. For example, considering an option -c, we want to get the default value in the following cases: perf command -c -d perf command -d -c And the foo value when it's given: perf command -c foo -d perf command -d -c foo That's also why PARSE_OPT_LASTARG_DEFAULT is extended here to support default values whatever the position of the option, not only in the end. Should it now be renamed to PARSE_OPT_ARG_DEFAULT ?
