Witryna27 mar 2024 · The next line we see that z is being loaded into ecx, and then executes imul with eax as the first operand and ecx as the second. This instruction takes the second operand and multiplies it by the first and stores the result in the first operand. This would translate to: x *= z; The original source performs all of this in the return statement.

Witryna†We have two different multiplication instructions MUL Source ;for unsigned multiplication IMUL Source ;for signed multiplication Where Source must be either Mem or Reg 1. Source is being multiplied by AL if Source is of type BYTE AX if Source is of type WORD EAX if Source is of type DWORD 2. WitrynaIMUL Instruction : IMUL source This instruction multiplies a signed byte from some source and a signed byte in AL, or a signed word from some source and a signed word in AX. The source can be register or memory location. When a signed byte (8-bit) is multiplied by AL a signed result will be put in AX. (AL) × (8-bit operand) → (AX)

WitrynaThe 80386 has separate multiply instructions for unsigned and signed operands. MUL operates on unsigned numbers, while IMUL operates on signed integers as well as unsigned. MUL (Unsigned Integer Multiply) performs an unsigned multiplication of the source operand and the accumulator.

Witryna20 wrz 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. Witryna17 gru 2016 · @RossRidge: IMUL sets CF and OF if the upper-half is not the sign-extension of the low half (even the multi-operand versions work that way, so detecting unsigned wraparound when using 2 or 3 operand imul can't be done from just the flags) – Peter Cordes Dec 16, 2016 at 22:47 Show 3 more comments 2 Answers Sorted by: 3

WitrynaThese 32x32 => 32-bit forms of imul work correctly for signed or unsigned; the results of one-operand mul and imul only differ in the upper half (in EDX ), not the low-half EAX output.
