The strength reduce problems on Intel and other platforms with small register sets have not been fixed. The example program that demonstrates the bug changes in subtle ways from release to release but it isn't fixed yet. I'd add -fno-strength-reduce if you just HAVE to use -O2. I've been bitten by the bug too many times so I stick with -O for everything. --=20 Note: See http://www.members.home.net/graywane/ for PGP information. --CdrF4e02JqNVZeln Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.4 (FreeBSD) Comment: For info see http://www.gnupg.org iEYEARECAAYFAjrTtdgACgkQeHdFaBWUGN2OMwCgnwHPpdNZBJRbw76j1ajeFEq7 RzkAnRLc5FIVQ90AYpSjS08Q/B3Z8GkB =NMjv -----END PGP SIGNATURE----- --CdrF4e02JqNVZeln-- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
