Thanks Michael. Just wanted to make sure I understood. The "do no harm" goal and the Thumb2 libgcc seem to be somewhat contradictory however. I realize that choices need to be made and only odd ducks like me will likely run into issues. My particular case is wanting to build u-boot for old and new ARM chips with the same gcc. U-Boot has its own libgcc that I can use as a work around.
