[PATCH v3 00/17] perf tools: Move perf subcommand framework to a library
From: Josh Poimboeuf
Date: Sun Dec 13 2015 - 23:19:03 EST
Ingo suggested that I factor out the perf subcommand functionality
(originally copied from git) into tools/lib so that it can be used by
stacktool[*] and possibly others.
All the subcommand option handling files have been moved into a new
library named libsubcmd.a, including parse-options.c, run-command.c,
exec_cmd.c, help.c, usage.c, and pager.c.
Patches 1-6 are some assorted cleanups I discovered in the process of
making the patch set. They're completely separate from the rest of the
patches and can be merged independently.
Patches 7-15 are some cleanups and splitting up of the code related to
the creation of the new library.
Patch 16 does the actual moving of the files and creation of the new
libsubcmd.a library in tools/lib/subcmd.
Patch 17 updates the header guards for the moved .h files.
Based on acme/perf/core.
These patches can also be found in the 'perf-subcmd-v3' branch in the
following repo:

[*] https://lkml.kernel.org/r/cover.1445443144.git.jpoimboe@xxxxxxxxxx
v3:
- Remove dependencies on util.h, cache.h, abspath, ctype, strbuf, term,
usage, wrapper
- Move to a new 'libsubcmd' library in tools/lib/subcmd
- Rebase onto Namhyung's patches which remove the browser dependency
from parse-options.c
- Get rid of the util_cfg struct in favor of file-specific init
functions
- Split up the patches better
- Document the fact that parse_options*() can exit
- Convert parse-options.c internal functions to static
- Rename exec_cmd.* to exec-cmd.*
- Add new astrcat() and astrcatf() functions to replace strbuf
- Add some more fixes related to 'make O=' and 'make clean' (though
a 'make clean' is no longer required and these patches are now
unrelated to libsubcmd)
v2:
- Fix 'make clean' to remove tests/llvm-src-*.c and other leftover
files
- Fix description for second-to-last patch
