HI Michael,
The build log can be found at http://people.linaro.org/~chaoyang/shared_sources/build_2011-08-19_20-33.log
The benchmark wiki page https://wiki.linaro.org/ChaoYang/Sandbox/gccoptimization is updated on 1. Adding benchmark for -fno-inline-function option (the size is reduced a bit) 2. Replacing O2 with O3 in build/core/combo/select.mk (a bit better results)
Thanks and regards

HI Bero, What I did was changing both Os and O2 to O3 in TARGET_linux-arm.mk. I

it
is risky to change those. But I don't think it should be a big problem.
Do you have the build log? You could do a quick grep over it to see if the GCC command line is sane.
