[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.

fix bloat-o-meter for ppc64 bloat-o-meter assumes that a '.' anywhere in a symbol's name means that it is static and prepends 'static.' to the first part of the symbol name, discarding the portion of the name that follows the '.'. However, the names of function entry points begin with '.' in the ppc64 ABI. This causes all function text size changes to be accounted to a single 'static.' entry in the output when comparing ppc64 kernels. Change getsizes() to ignore the first character of the symbol name when searching for '.'.
