See Pre-UAL pseudo-instruction NOP on page AppxH-2472 for details of NOP before the introduction of UAL and the ARMv6K and ARMv6T2 architecture variants. Note The timing effects of including a NOP instruction in a program are not guaranteed. It can increase execution time, leave it unchanged, or even reduce it. Therefore, NOP instructions are not suitable for timing loops. } @encoding (t1) { @half 1 0 1 1 1 1 1 1 0 0 0 0 0 0 0 0 @syntax { @asm nop } } @encoding (T2) { @word 1 1 1 1 0 0 1 1 1 0 1 0 1 1 1 1 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 @syntax { @asm nop.w } } @encoding (A1) { @word cond(4) 0 0 1 1 0 0 1 0 0 0 0 0 1 1 1 1 0 0 0 0 0 0 0 0 0 0 0 0 @syntax { @asm nop @rules { check g_arm_instruction_set_cond(cond) } } }
