perf quote: Disentangle headers

2016-07-12T18:19:55+00:00

No need to include stdio.h from quote.h, also forward declare strbuf. Cc: Adrian Hunter Cc: David Ahern Cc: Jiri Olsa Cc: Namhyung Kim Cc: Wang Nan Link: http://lkml.kernel.org/n/tip-k3kbcxhctpxvz6ckve3kv6c1@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Make alias handler to check return value of strbuf

2016-05-10T14:56:52+00:00

Make alias handler and sq_quote_argv to check the return value of strbuf APIs. In sq_quote_argv() calls die(), but this fix handles strbuf failure as a special case and returns to caller, since the caller - handle_alias() also has to check the return value of other strbuf APIs and those checks can be merged to one if() statement.

perf tools: Remove some unused functions

2010-05-19T02:03:35+00:00

Without the bloated cplus_demangle from binutils, i.e building with: $ make NO_DEMANGLE=1 O=~acme/git/build/perf -j3 -C tools/perf/ install Before: text data bss dec hex filename 471851 29280 4025056 4526187 45106b /home/acme/bin/perf After: [acme@doppio linux-2.6-tip]$ size ~/bin/perf text data bss dec hex filename 446886 29232 4008576 4484694 446e56 /home/acme/bin/perf So its a 5.3% size reduction in code, but the interesting part is in the git diff --stat output: 19 files changed, 20 insertions(+), 1909 deletions(-) If we ever need some of the things we got from git but weren't using, we just have to go to the git repo and get fresh, uptodate source code bits.

perf_counter tools: Add more warnings and fix/annotate them

2009-07-01T10:49:48+00:00

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/

2009-06-06T18:33:43+00:00

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. Cc: Peter Zijlstra Cc: Mike Galbraith Cc: Paul Mackerras Cc: Arnaldo Carvalho de Melo LKML-Reference: Signed-off-by: Ingo Molnar
