As I understand= =20 this is mostly due to tendra's way of constructing objects: It translates t= o=20 a machine independent intermediate language where it does all the=20 optimisations and only thereafter "installs" - in tendra speak - to the=20 target architecture. This is quite nice for cross builds as you can do the= =20 expensive first pass on fast hardware and do the "installation" on the=20 target. It has the downside for __asm and the like. I might be all wrong, though. =2D-=20 /"\ Best regards, | mlaier@freebsd.org \ / Max Laier | ICQ #67774661 X http://pf4freebsd.love2party.net/ | mlaier@EFnet / \ ASCII Ribbon Campaign | Against HTML Mail and News --nextPart8944734.ZhXnMDZBo0 Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2.2 (FreeBSD) iD8DBQBEpsoSXyyEoT62BG0RAuGQAJ9gjmDQCa6a5IpGB3eT6vs/cY5cPgCfbowy EmCiRPhMwkIPxS/b7IOYv+Y= =EKna -----END PGP SIGNATURE----- --nextPart8944734.ZhXnMDZBo0--
