* perf subcmd: Create subcmd libraryJosh Poimboeuf2015-12-171-228/+0
| | | | | | | | | | | | | | | Move the subcommand-related files from perf to a new library named libsubcmd.a. Since we're moving files anyway, go ahead and rename 'exec_cmd.*' to 'exec-cmd.*' to be consistent with the naming of all the other files.

* perf tools: Document the fact that parse_options*() may exitJosh Poimboeuf2015-12-161-0/+3
| | | | | | | | | | | | | Generally, calling exit() from a library is bad practice. Eventually these functions might be redesigned so that they don't exit. For now, just document the fact that they do.

* perf tools: Make options always available, even if required libs not linkedWang Nan2015-12-141-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch keeps options of perf builtins same in all conditions. If one option is disabled because of compiling options, users should be notified. Masami suggested another implementation in [1] that, by adding a OPTION_NEXT_DEPENDS option before those options in the 'struct option' array, options parser knows an option is disabled. However, in some cases this array is reordered (options__order()). In addition, in parse-option.c that array is const, so we can't simply merge information in decorator option into the affacted option. This patch chooses a simpler implementation that, introducing a set_option_nobuild() function and two option parsing flags. Builtins with such options should call set_option_nobuild() before option parsing. The complexity of this patch is because we want some of options can be skipped safely. In this case their arguments should also be consumed. Options in 'perf record' and 'perf probe' are fixed in this patch.

* perf: Fix endianness argument compatibility with OPT_BOOLEAN() and introduce ↵Ian Munsie2010-04-141-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OPT_INCR() 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: Ian Munsie <imunsie@au.ibm.com> Acked-by: David S.

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.

* perf_counter tools: Add more warnings and fix/annotate themIngo Molnar2009-07-011-13/+12
| | | | | | | | | | | | | | | | | Enable -Wextra. This found a few real bugs plus a number of signed/unsigned type mismatches/uncleanlinesses. It also required a few annotations All things considered it was still worth it so lets try with this enabled for now.

* perf_counter tools: Move from Documentation/perf_counter/ to tools/perf/Ingo Molnar2009-06-061-0/+174
Several people have suggested that 'perf' has become a full-fledged tool that should be moved out of Documentation/. Move it to the (new) tools/ directory.
