perf script: Add --inline option for debugging

2017-05-24T06:41:48+00:00

The --inline option is to show inlined functions in callchains.

For example:

  $ perf script
  a.out  5644 11611.467597:     309961 cycles:u:
                     790 main (/home/namhyung/tmp/perf/a.out)
                   20511 __libc_start_main (/usr/lib/libc-2.25.so)
                     8ba _start (/home/namhyung/tmp/perf/a.out)
  ...

  $ perf script --inline
  a.out  5644 11611.467597:     309961 cycles:u:
                     790 main (/home/namhyung/tmp/perf/a.out)
                         std::__detail::_Adaptor, double>::operator()
                         std::uniform_real_distribution::operator() >
                         std::uniform_real_distribution::operator() >
                         main
                   20511 __libc_start_main (/usr/lib/libc-2.25.so)
                     8ba _start (/home/namhyung/tmp/perf/a.out)
  ...

perf tools: Remove string.h, unistd.h and sys/stat.h from util.h

2017-04-24T16:43:33+00:00

Not needed in this header, added to the places that need FILE,
putchar(), access() and a few other prototypes.

perf tools: Include sys/param.h where needed

2017-04-24T16:43:30+00:00

As it is going away from util.h, where it is not needed.

This is mostly for things like MAXPATHLEN, MAX() and MIN(), these later
two probably should go away in favor of its kernel sources replacements.

perf tools: Add signal.h to places using its definitions

2017-04-20T16:22:43+00:00

And remove it from util.h, disentangling it a bit more.

perf tools: Remove include dirent.h from util.h

2017-04-19T16:01:55+00:00

The files using the dirent.h routines should instead include it,
reducing the includes hell that lead to longer build times.

perf tools: Include errno.h where needed

2017-04-19T16:01:51+00:00

Removing it from util.h, part of an effort to disentangle the includes
hell, that makes changes to util.h or something included by it to cause
a complete rebuild of the tools.

perf tools: Move extra string util functions to util/string2.h

2017-04-19T16:01:51+00:00

Moving them from util.h, where they don't belong. Since libc already
have string.h, name it slightly differently, as string2.h.
