EFLAGS

EFLAGS Types

This is a 32-bit register in x86 assembly language that contains various flags providing information about the result of an operation. These flags are crucial for understanding the outcome of arithmetic operations and determining the next steps in the program flow.

Flags	Description
CF	Carry flag, set when an arithmetic operation generates a carry or borrow.
OF	Overflow flag, set when an operation generates a result too large for the destination register.
SF	Sign flag, set when the result of an operation is negative.
ZF	Zero flag, set when the result of an operation is zero.
AC	Alignment check flag, set when an unaligned memory access occurs.
PF	Parity flag, set when the least-significant byte of the result has an even number of set bits.
IF	Interrupt flag, determines whether the CPU recognizes external interrupts.

If the flag is set to 1, it means the condition is met; otherwise, it’s 0. I can check more register flags here.
