Even though I didn't observe such problems with libgcc soft-floats on PowerPC I'd like to stress it in some more systematic way, but the testing packages I looked at were not readily available for this arch, low level pieces were missing there etc. For the SoftFloat lib there's accompanying TestFloat but it's closely tied to its parent library, so no easy way to use it with libgcc soft-float. Any hints on what would be best to pick up? Rafal
