For what it's worth, this is how most hardware implements many of the floating-point set-on instructions. It's even easier there because you also have per-operand negation. Implementing the full set as instructions / pseudo-ops does have the advantage of making IR dumps a lot more readable. *shrug* -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org/ iEYEARECAAYFAk5cBwYACgkQX1gOwKyEAw970gCfWcTEDyDYCnC8JelTcoNWnTI0 RRYAniUCKzykrqsRVkTnJVCDcVyc3Byd =Izn1 -----END PGP SIGNATURE----- _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
