Taras, I am having difficulty reproducing your results. I am using a Slackware Linux user's build script to build firefox with PGO enabled:

http://www.linuxquestions.org/questions/linux-software-2/building-firefox-3-6-a-profile-guided-optimization-pgo-automated-build-script-784164/

I made some improvements to her script and contributed them back to the thread at linuxquestions.org, however, I am unable to reproduce any improvements in Sun Spider benchmarks when comparing her script's PGO-build to the system Firefox, even if both are patched to enable TraceMonkey support on 64-bit Linux.

I think my difficulty is because -freorder-blocks-and-partition is not being passed to GCC. What are you doing to pass -freorder-blocks-and-partition to GCC during the initial build?
