What is Nopl in assembly?

What is endbr64?
It stands for “End Branch 64 bit” — or more precisely, Terminate Indirect Branch in 64 bit.
What does Imul do in assembly?
Description. The single-operand form of imul executes a signed multiply of a byte, word, or long by the contents of the AL, AX, or EAX register and stores the product in the AX, DX:AX or EDX:EAX register respectively.
What is Lea Assembly?
lea — Load effective address. The lea instruction places the address specified by its first operand into the register specified by its second operand. Note, the contents of the memory location are not loaded, only the effective address is computed and placed into the register.
What does push RBP do?
push rbp instruction pushes the value of the register rbp onto the stack. Because it “pushes” onto the stack, now the value of rsp is the memory address of the new top of the stack.
What is the difference between MUL and Imul?
The MUL instruction multiplies unsigned numbers. IMUL multiplies signed numbers. Multiplying two 8-bit numbers produces a 16-bit result returned in AX. Multiplying two 16-bit operands yields a 32-bit result in DX:AX.
What does MOV mean in assembly?
Data Movement Instructions The mov instruction copies the data item referred to by its second operand (i.e. register contents, memory contents, or a constant value) into the location referred to by its first operand (i.e. a register or memory).
What is Movzx Assembly?
Description. movzx reads the contents of the register or effective address as a word or byte. movzx then sign-extends the 16- or 32-bit value to the operand-size attribute of the instruction. The result is stored in the destination register by movzx.
What does RBP do in assembly?
rbp is the base pointer, which points to the base of the current stack frame, and rsp is the stack pointer, which points to the top of the current stack frame.
What is Imul Assembly?
How does MUL work?
The MUL (unsigned multiply) instruction multiplies an 8-, 16-, or 32-bit operand by either AL, AX, or EAX. The Carry flag indicates whether or not the upper half of the product contains significant digits.
