For an ordinary near JMP in 8086/x86, which of the following flags are set by…

Concept

Processor status flags record conditions produced by data-processing operations, such as a sign, carry, or auxiliary carry. Instruction side effects are defined by the ISA; for the ordinary 8086/x86 JMP form assessed here, an unconditional control transfer changes the next instruction address without producing an arithmetic or logical result.

Application

1. Under the ordinary 8086/x86 JMP form, the processor loads the jump target into the instruction pointer and continues fetching from that address.

2. The flags register is left unchanged: JMP neither forces SF, AF, or CF to 1 nor clears them; any values already present remain intact.

Contrast

• SF and CF are status flags associated with the sign of a result and an unsigned carry or borrow.

• AF and CF are carry-related status flags for the low-nibble boundary and the most-significant-bit boundary.

• All flags includes both status and control flags, which are affected only by their relevant instruction classes.

• No flag is set describes an instruction that redirects control flow while preserving the existing flags register.

Result

Therefore, executing JMP sets no flag; the accepted value is “No flag is set.”
