This tickled some half-buried memory and made me look again. VMAC's core operation is a 64 by 64 to 128 bits multiplication. This can't be expressed in portable C and even if you resort to inline assembly, not all 64-bit archs may support this operation. (E.g., I don't see a corresponding instruction in the SPARCv9 manual.) -- Christian "naddy" Weisgerber naddy@xxxxxxxxxxxx _______________________________________________ openssh-unix-dev mailing list openssh-unix-dev@xxxxxxxxxxx https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev
