Explore: Flags Operands

bitwise operations are presented as two-operand instructions where the result replaces one of the input operands. On simple low-cost processors, typically

two operands. The flags SF, ZF, PF are modified while the numerical result of the AND is discarded. The OF and CF flags are set to 0, while AF flag is

register, flag register, or condition code register (CCR) is a collection of status flag bits for a processor. Examples of such registers include FLAGS register

cannot occur when the sign of two addition operands are different (or the sign of two subtraction operands are the same). When binary values are interpreted

processor flags to check for overflow conditions. The carry flag is set when the result of an addition or subtraction, considering the operands and result

most modern and widely used. The and of a set of operands is true if and only if all of its operands are true, i.e., A ∧ B {\displaystyle A\land B} is

up to 4 operands. Like the VEX coding scheme, the EVEX prefix unifies existing opcode prefixes and escape codes, memory addressing and operand length modifiers

memory operands is relaxed. Unlike their non-VEX coded counterparts, most VEX coded vector instructions no longer require their memory operands to be aligned

first operand is both the first source operand and the destination operand. fsubr and fdivr should be singled out as first swapping the source operands before

complement of) both operands before multiplying. The multiplier will then be positive so the algorithm will work. Because both operands are negated, the
