H. Peter Anvin	2469b8b66e	Add {rex} prefix, simplify prefix handling, better error messages ... Add a {rex} prefix to force REX encoding (typically a redundant 40h prefix). For prefix parsing, we can use t_inttwo to encode the prefix slot number. Give more verbose error messages for encoding mismatches.	2021-04-27 11:37:42 -07:00
H. Peter Anvin	621a69ac5c	Add {vex3} and {vex2} prefixes by analogy with {evex} ... Allow specifying {vex3} or {vex2} (the latter is currently always redundant, unless we end up with instructions at some point can be specified with legacy prefixes or VEX) to select a specific encoding of VEX-encoded instructions.
