Vex-0f3a-execute

Dispatch function for VEX-encoded instructions in the second three-byte opcode map

Signature

(vex-0f3a-execute proc-mode 
                  start-rip temp-rip prefixes rex-byte 
                  vex-prefixes opcode modr/m sib x86) 
 
  → 
x86

Arguments

temp-rip — temp-rip points to the byte following the SIB byte (if present), or the ModR/M byte (if present with no SIB byte), or the opcode byte (if there is no ModR/M byte).

vex-prefixes — Completely populated when this function is called.

Returns

x86 — Type (x86p x86), given (x86p x86).
