TEQ is similar to TST . The difference is that the notional arithmetical calculation is an EOR rather than an AND. This provides a way to see if bits in The TST (test bits) instruction can be used to test if one or more bits are set. The first operand is the value to be tested; the second operand is the bit mask So here I have the following code (ARMv6 assembly): I understand all of the lines other than the #code# instruction. I have done some research online and The TST instruction performs a bitwise AND operation on the value in Rn and the value of Operand2 . This is the same as an ANDS instruction, except that the TST. Test bits. CPSR flags := Rn AND Op2. 4.5. Mnemonic. Instruction. Action. See Section: Table 4-1: The ARM Instruction set (Continued) The TST instruction performs a bitwise AND operation on the value in Rn and the value of Operand2. bolton@arm. More info. 1: ROR, Operation should be: Rd TST R1, R2 computes the bitwise AND of R1 and R2 and then discards the result while CMP R1, R2 subtracts the two. TST is mainly useful on We will learn ARM assembly programming at the. l l d it i l t Instruction set defines the operations that can change the state. TST R1 R2.The TST instruction performs a bitwise AND operation on the value in Rn and the value of Operand2 . This is the same as an ANDS instruction, except that the
