Dunno about that. > For non-liw architectures this is the size of the smallest instruction. If by "non-liw" you mean "RISC", then all instructions have the same size and this is trivial. For variable-length instruction sets, things just seem to work best when=20 base-insn-size includes all the non-operand bits of the longest instruction. - FChE --ctP54qlpMx3WjD+/ Content-Type: application/pgp-signature Content-Disposition: inline Content-length: 189 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.7 (GNU/Linux) iD8DBQE997S3VZbdDOm/ZT0RAg8YAJ9Ay5qXy9vJFPtvY1uP3gaMDeek/gCdFQFE 2HGTk/ywTN6Jevi8EoEmhJo= =rrU1 -----END PGP SIGNATURE----- --ctP54qlpMx3WjD+/--
