  • e7f01d1e3   perf tools: Use scnprintf where applicable ... Browse Code »

    Several places were expecting that the value returned was the number of
    characters printed, not what would be printed if there was space.

    Fix it by using the scnprintf and vscnprintf variants we inherited from
    the kernel sources.

    Some corner cases where the number of printed characters were not
    accounted were fixed too.

  • a41794cdd   perf tools: Remove some unused functions ... Browse Code »

    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.

  • f37a291c5   perf_counter tools: Add more warnings and fix/annotate them ... Browse Code »

    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.
