Hi all,
this patch fixes bootstrap on FreeBSD PowerPC and hopefully all other
PowerPC targets which do not have float128 support.
The patch itself is a bandaid to survive stage4. We have to come up with
a better solution for FreeBSD and all other soft float targets which do
not support float128.
The patch was tested by Michael Meissner on different POWER machines.
Ok to commit to trunk?
TIA,
Andreas
