WitrynaDescription; Decrements the stack pointer and then stores the source operand on the top of the stack. The address-size attribute of the stack segment determines the stack pointer size (16 bits or 32 bits), and the operand-size attribute of the current code segment determines the amount the stack pointer is decremented (2 bytes or 4 bytes). WitrynaAgain, the destination is the first register in an assembly language instruction, but it is the second register field (Rd) in the machine language instruction. The immediate of the ADD instruction (42) can be encoded in 8 bits, so no rotation is needed ( …

Using the sign-extended-imm8 encoding when available is always good. It's equal length for 16-bit, but shorter for 32-bit operand-size, so it simplifies your code to always choose imm8. With operand-size of 32-bit, op eax, imm32 is 5 bytes, vs. op r/m32, imm8 still being 3 bytes. (Not counting any prefixes needed to set operand-size or other ...

The AAM mnemonic is interpreted by all assemblers to mean adjust to ASCII (base 10) values. To adjust to values in another number base, the instruction must be hand coded in machine code (D4 imm8). iman gatti father

WitrynaThe MOV instruction cannot be used to load the CS register. Attempting to do so results in an invalid opcode exception (#UD). To load the CS register, use the far JMP, CALL, or RET instruction. If the destination operand is a segment register (DS, ES, FS, GS, or SS), the source operand must be a valid segment selector.
