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.
