No to Linaro
Developers with Linaro, an open-source, not-for-profit organization that optimizes software and tools for Linux running on ARM processors, created a build of Android ICS that runs faster than the releases put out by the Android Open Source Project, on which the CyanogenMod community bases its custom ROMs that include CM9. They achieved this by improving the toolchain and using GCC 4.7. Unfortunately, CyanogenMod decided not to incorporate Linaro’s code due to compatibility issues.
