--oC1+HKm2/end4ao3 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable I've been doing some experiments on mixing NaNs using x87, SSE, sparc64 on FreeBSD, Solaris/SPARC and Linux/ARM. My conclusion is that there is no standardisation between the FPUs (and the base gcc also evaluates constant expressions differently to the target FPU). However, I've also noticed that FreeBSD/sparc64 and SunStudio on Solaris10/SPARC also give different results. Should we modify the FreeBSD/sparc64 FP exception handling code to match Solaris? --=20 Peter Jeremy --oC1+HKm2/end4ao3 Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (FreeBSD) iEYEARECAAYFAlAMevgACgkQ/opHv/APuIfd8ACgm5EDlesGNSWnHVgaJyqqVx+/ kSIAn1N9MoRaA7Vc+iwou/9i3oqDE5hi =IKAn -----END PGP SIGNATURE----- --oC1+HKm2/end4ao3--
