NettetThis is even, so our next number is 10 / 2 = 5. This is odd, so our next number is 3 ⋅ 5 + 1 = 16. This is even, so we then go to 8, which is still even, so we go to 4, then 2, and 1. In translating this to ARM's assembly language, we must confront the fact that ARM lacks any instructions related to division. NettetYou can use PC for Rd and Rm in the other syntax, but this is deprecated in ARMv6T2 and above. If you use PC as , the value used is the address of the instruction plus 8. Rm. If you use PC as : Rd. Execution branches to the address corresponding to the result. If you use the S suffix, the SPSR of the current mode is copied to the CPSR.

Nettet15. sep. 2012 · MOV is a real instruction (a 32-bit instruction) , LDR is a pseudo instruction (the assembler will use multiple 32-bit instructions to achieve the goal). For data move, if the immediate value is small, the assembler will use “mov” to implement it, so mov and ldr are exactly the same if the immediate value less or equal to 255. For example, for Nettet7. mar. 2024 · 3. tst reg,reg sets flags according to the value, so mov dst,src + tst dst,dst would be the naive drop-in replacement for any case. Or in your case, your str …
