Yes that's correct. Only left is some patch to fix register save/restore for trampolines. >> BTW had to throw in another patch that fixes an issue with the >> 's_fma.c'. > This could be new. It is new. Attached it. In case you find something wrong with it, there are some hours left before everything is rebuilt&testet and I start posting this upstream. BTW are there any special test-cases you use for testing your changes? So far I can only imagine to put this in a chroot and see whether it "works". >>>> Ok this goes a little beyond my experience with Debian development. >>>> Will take some time to figure out.

I'm already tinkering with multistrapping a chroot from snapshot.debian.org (currently trying May 9 2011). If I'm lucky this will soon work. So now I have a double-chroot? One to install sbuild, and a nested one that is used by sbuild? :) cheers, David -- GnuPG public key: http://dvdkhlng.users.sourceforge.net/dk.gpg Fingerprint: B17A DC95 D293 657B 4205 D016 7DEF 5323 C174 7D40
