3.1.1.12 Real-Address Mode Exceptions Section
The “Real-Address Mode Exceptions” section lists the exceptions that can occur when
the instruction is executed in real-address mode (see Table 3-3).
3.1.1.13 Virtual-8086 Mode Exceptions Section
The “Virtual-8086 Mode Exceptions” section lists the exceptions that can occur when
the instruction is executed in virtual-8086 mode (see Table 3-3).
3.1.1.14 Floating-Point Exceptions Section
The “Floating-Point Exceptions” section lists exceptions that can occur when an x87
FPU floating-point instruction is executed. All of these exception conditions result in
a floating-point error exception (#MF, vector number 16) being generated. Table 3-4
associates a one- or two-letter mnemonic with the corresponding exception name.
See “Floating-Point Exception Conditions” in Chapter 8 of the Intel® 64 and IA-32
Architectures Software Developer’s Manual, Volume 1, for a detailed description of
these exceptions.
