[PATCH] tiny: Add bloat-o-meter to scripts This is a rewrite of Andi Kleen's bloat-o-meter with sorting and reporting of gainers/decliners. Sample output: add/remove: 0/8 grow/shrink: 2/0 up/down: 88/-4424 (-4336) function old new delta __copy_to_user_ll 59 103 +44 __copy_from_user_ll 59 103 +44 fill_note 32 - -32 maydump 58 - -58 dump_seek 67 - -67 writenote 180 - -180 elf_dump_thread_status 274 - -274 fill_psinfo 308 - -308 fill_prstatus 466 - -466 elf_core_dump 3039 - -3039 The summary line says: no functions added, 8 removed two functions grew, none shrunk we gained 88 bytes and lost 4424 (or -4336 net) This work was sponsored in part by CE Linux Forum Signed-off-by: Matt Mackall <mpm@selenic.com> Cc: Andi Kleen <ak@muc.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

bloat-o-meter: include read-only data section in report I'm not sure why the read-only data section is excluded from the report, it seems as relevant as the other data sections (b and d). I've stripped the symbols starting with __mod_ as they can have their names dynamically generated and thus comparison between binaries is not possible.

scripts/bloat-o-meter: use .startswith rather than fragile slicing str.startswith has existed since at least Python 2.0, in 2000; use it rather than a fragile comparison against an initial slice of a string, which requires hard-coding the length of the string to compare against.

scripts/bloat-o-meter: ignore changes in the size of linux_banner linux_banner can change size due to changes in the compiler, build number, or the user@host the system was compiled on; ignore size changes in linux_banner entirely.

kbuild, bloat-o-meter: fix static detection Disable static detection: the static currently drops a lot of useful information including clones generated by gcc. Drop this. The statics will appear now without static. prefix. But remove the LTO .NUMBER postfixes that look ugly Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Michal Marek <mmarek@suse.cz>
