Cltd assembly instruction
WebSep 20, 2024 · The imul instruction has two basic formats: two-operand (first two syntax listings above) and three-operand (last two syntax listings above). The two-operand form multiplies its two operands together and stores the result in the first operand. The result (i.e. first) operand must be a register. WebWhat is CLTD Assembly? Description. cltd converts the signed long in EAX to a signed double long in EDX:EAX by extending the most-significant bit (sign bit) of EAX into all bits of EDX. What is CWD assembly language? This instruction (Convert signed Word to signed Doubleword) copies the sign bit of a word in AX to all the bits of DX.

WebThe IDIV (signed divide) instruction performs signed integer division, using the same operands as the DIV instruction.. For both DIV and IDIV, all of the arithmetic status flags are undefined after the operation. When doing 8-bit division, you must sign-extend the dividend into AH before using IDIV..
