SIMD Floating-Point Exceptions
Invalid if SNaN operand and invalid if QNaN and predicate as listed in above table,
Denormal.
Protected Mode Exceptions
#GP(0) For an illegal memory operand effective address in the CS, DS,
ES, FS or GS segments.
If a memory operand is not aligned on a 16-byte boundary,
regardless of segment.
#SS(0) For an illegal address in the SS segment.
#PF(fault-code) For a page fault.
#NM If CR0.TS[bit 3] = 1.
#XM If an unmasked SIMD floating-point exception and CR4.OSXM-
MEXCPT[bit 10] = 1.
#UD If an unmasked SIMD floating-point exception and CR4.OSXM-
MEXCPT[bit 10] = 0.
If CR0.EM[bit 2] = 1.
If CR4.OSFXSR[bit 9] = 0.
