 Existing general-purpose x86 instructions support two operands rather
 than three operands.  To avoid requiring a \VEX{} prefix for all new
 CHERI instructions, most instructions are defined with two operands
-rather than three.  New instructions thatrequire three operands must

 be encoded using a \VEX{} prefix.
 
 Note that all of these instructions would only be valid in 64-bit mode
