INSTRUCTION SET REFERENCE, A-M
MOVNTQ—Store of Quadword Using Non-Temporal Hint
#SS(0) For an illegal address in the SS segment.
#PF(fault-code) For a page fault.
#NM If CR0.TS[bit 3] = 1.
#MF If there is a pending x87 FPU exception.
#UD If CR0.EM[bit 2] = 1.
If CPUID.01H:EDX.SSE[bit 25] = 0.
If the LOCK prefix is used.
#AC(0) If alignment checking is enabled and an unaligned memory
reference is made while the current privilege level is 3.
Real-Address Mode Exceptions
#GP(0) If a memory operand is not aligned on a 16-byte boundary,
regardless of segment.
If any part of the operand lies outside the effective address
space from 0 to FFFFH.
#NM If CR0.TS[bit 3] = 1.
#MF If there is a pending x87 FPU exception.
#UD If CR0.EM[bit 2] = 1.
If CPUID.01H:EDX.SSE2[bit 26] = 0.
#UD If the LOCK prefix is used.
Virtual-8086 Mode Exceptions
Same exceptions as in real address mode.
#PF(fault-code) For a page fault.
#AC(0) If alignment checking is enabled and an unaligned memory
reference is made.
Compatibility Mode Exceptions
Same exceptions as in protected mode.
64-Bit Mode Exceptions
#SS(0) If a memory address referencing the SS segment is in a non-
canonical form.
#GP(0) If the memory address is in a non-canonical form.
#PF(fault-code) For a page fault.
#NM If CR0.TS[bit 3] = 1.
#MF If there is a pending x87 FPU exception.
