Each time it will remove 1 from r0 and check if it resulted in a negative number or not. If it results in a negative number it will not branch and the wait is over. So if you insert 100 it will probably divide 100 on 8 and then insert the nearest hole number of that in to r0. +To save space the compiler makes some optimizations in the code. +So wait is now compiled as a function and takes an argument in r0 instead of +just setting a value before it runs. */ // // Commit your answers (bare2_3) -- GitLab
