JMPE - x86-64 instruction reference

jmpeJump to IA-64 instruction set 
On an Itanium running IA-32 code, jumped to the target and switched to the IA-64 instruction set; x86 processors raise an invalid-opcode fault instead.

Operands imm A branch target, written as a label or address. NASM calculates the displacement from the end of the instruction. NASM selects a short or near encoding according to the target’s reach and any size constraint. 
r/m A general-purpose register or memory location matching the operation’s size, for example rax or qword [rbp-8]. The byte registers ah, bh, ch and dh cannot be used with a REX prefix, including when the memory address uses r8–r15.
