None
Numeric Exceptions:
Protected Mode Exceptions:
#GP(0) for an illegal memory operand effective address in the CS, DS, ES, FS or GS
segments; #SS(0) for an illegal address in the SS segment; #PF(fault-code) for a page
fault; #UD if CR0.EM = 1; #NM if TS bit in CR0 is set; #UD if CRCR4.OSFXSR(bit 9) =
0; #UD if CPUID.XMM(EDX bit 25) = 0.
Real Address Mode Exceptions:
Interrupt 13 if any part of the operand would lie outside of the effective address space
from 0 to 0FFFFH; #UD if CR0.EM = 1; #NM if TS bit in CR0 is set; #UD if
CRCR4.OSFXSR(bit 9) = 0; #UD if CPUID.XMM(EDX bit 25) = 0.
Virtual 8086 Mode Exceptions:
Same exceptions as in Real Address Mode; #PF(fault-code) for a page fault.

Itanium Mem Faults VHPT Data Fault, Data TLB Fault, Alternate Data TLB Fault, Data
The usage of Repeat Prefixes (F2H, F3H) with SHUFPS is reserved. Different processor
Comments:
implementations may handle this prefix differently. Usage of this prefix with SHUFPS
risks incompatibility with future processors.
