INSTRUCTION SET REFERENCE, A-M
Floating-Point Exceptions
#IS Stack underflow or overflow occurred.
#IA Source operand is an SNaN. Does not occur if the source
operand is in double extended-precision floating-point format
(FLD m80fp or FLD ST(i)).
#D Source operand is a denormal value. Does not occur if the
source operand is in double extended-precision floating-point
format.
Protected Mode Exceptions
#GP(0) If destination is located in a non-writable segment.
If a memory operand effective address is outside the CS, DS,
ES, FS, or GS segment limit.
If the DS, ES, FS, or GS register is used to access memory and it
contains a NULL segment selector.
#SS(0) If a memory operand effective address is outside the SS
segment limit.
#NM CR0.EM[bit 2] or CR0.TS[bit 3] = 1.
#PF(fault-code) If a page fault occurs.
#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 If a memory operand effective address is outside the CS, DS,
ES, FS, or GS segment limit.
#SS If a memory operand effective address is outside the SS
segment limit.
#NM CR0.EM[bit 2] or CR0.TS[bit 3] = 1.
Virtual-8086 Mode Exceptions
#GP(0) If a memory operand effective address is outside the CS, DS,
ES, FS, or GS segment limit.
#SS(0) If a memory operand effective address is outside the SS
segment limit.
#NM CR0.EM[bit 2] or CR0.TS[bit 3] = 1.
#PF(fault-code) If a page fault occurs.
#AC(0) If alignment checking is enabled and an unaligned memory
reference is made.
Compatibility Mode Exceptions
Same exceptions as in Protected Mode.
