WebJun 3, 2024 · As we saw last time, if you’re writing assembly by hand, you can just write LDR Rd, =#nnn and the assembler will figure out which MOV, MVN, or (worst case) LDR instruction will get you the value you want. It will disassemble as MOV, MVN, or LDR based on what the assembler ultimately chose. WebThe MVN instruction takes the value of Operand2, performs a bitwise logical NOT operation on the value, and places the result into Rd. In certain circumstances, the assembler can …
