scripts/bloat-o-meter: fix percent on <1% changes

2016-07-26T23:19:19Z

Python divisions are integer divisions unless at least one parameter is a float. The current bloat-o-meter fails to print sub-percentage changes: Total: Before=10515408, After=10604060, chg 0.000000% Force float division by using one float and pretty the print to two significant decimals: Total: Before=10515408, After=10604060, chg +0.84% Link: http://lkml.kernel.org/r/1465980311-23814-1-git-send-email-riku.voipio@linaro.org Signed-off-by: Riku Voipio Reviewed-by: Josh Triplett Cc: Vineet Gupta Cc: Michal Marek Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

scripts/bloat-o-meter: print percent change

2016-05-20T02:12:14Z

This adds an additional line of output (to reduce the chances of breaking any existing output parsers) which prints the total size before and after and the relative difference. add/remove: 39/0 grow/shrink: 12408/55 up/down: 362227/-1430 (360797) function old new delta ext4_fill_super 10556 12590 +2034 _fpadd_parts - 1186 +1186 ntfs_fill_super 5340 6164 +824 ... ... __divdf3 752 386 -366 unlzma 3682 3274 -408 Total: Before=5023101, After=5383898, chg 7.000000% ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Link: http://lkml.kernel.org/r/1463124110-30314-1-git-send-email-vgupta@synopsys.com Signed-off-by: Vineet Gupta Cc: Josh Triplett Cc: Michal Marek Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

scripts/bloat-o-meter: fix python3 syntax error

2016-01-15T00:00:49Z

In Python3+ print is a function so the old syntax is not correct anymore: $ ./scripts/bloat-o-meter vmlinux.o vmlinux.o.old File "./scripts/bloat-o-meter", line 61 print "add/remove: %s/%s grow/shrink: %s/%s up/down: %s/%s (%s)" % \ ^ SyntaxError: invalid syntax Fix by calling print as a function. Tested on python 2.7.11, 3.5.1 Signed-off-by: Sergey Senozhatsky Cc: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

bloat-o-meter: Ignore syscall aliases SyS_ and compat_SyS_

2014-08-23T20:08:48Z

This avoids double-counting size changes in syscall implementations. Signed-off-by: Josh Triplett

scripts/bloat-o-meter: use .startswith rather than fragile slicing

2013-11-07T09:47:13Z

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. Signed-off-by: Josh Triplett Signed-off-by: Andrew Morton Signed-off-by: Michal Marek

scripts/bloat-o-meter: ignore changes in the size of linux_banner

2013-11-07T09:46:54Z

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. Signed-off-by: Josh Triplett Signed-off-by: Andrew Morton Signed-off-by: Michal Marek

kbuild, bloat-o-meter: fix static detection

2013-11-06T21:25:59Z

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 Signed-off-by: Michal Marek

bloat-o-meter: include read-only data section in report

2011-03-23T00:44:17Z

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

2007-12-18T03:28:17Z

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 '.'. Signed-off-by: Nathan Lynch Cc: Matt Mackall Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
