Thanks for the data. A few questions:
- Do you have the raw data used to generate your pdfs available? Since
you gave me the binaries, if I have the data in terms of exactly what
addresses are being plotted I can correlate with the specific cold
functions via nm. Once I know what cold functions

Dear Jan and Teresa,
Jan was right that I've been using changes which were commited by
Teresa and do live in trunk. So the graph with time profile presented
in my previous post was really with enabled

Could be due to needing longer jump opcodes to reach the unlikely sections.
Dear Teresa,
I will today double check if the graphs are correct :)

So we see how things combine with -freorder-function
This patch enables -freorder-blocks-and-partition by default for x86
at -O2 and up. It is showing some modest gains in cpu2006 performance
with profile feedback and -O2 on an Intel Westmere system. Specifically,
I am seeing consistent improvements in 401.bzip2 (1.5-3%), 483.xalancbmk
(1.5-3%), and
Martin,
can you, please, generate the updated systemtap with
-freorder-blocks-and-partition enabled?
I am in favour of enabling this - it is usefull pass and it is pointless ot
have passes that are not enabled by default.
Is there reason why this would not work on other ELF target? Is it working
