#182540 - and so what Responding to: ???'s previous message |
a compiler can do ANYthing, in ANY fashion as long as the result is correct.
it would be fully legal for a compiler to do the following: C: a= b + c; resulting assembler: mov a,#0 loop1: inc a djnz b,loop1 loop2: inc a djnz c,loop2 no compiler make of any sense would do so, but it illustartes the point that it is be fully legal for a compiler to ahieve the result n any fashion Erik yes, I know the code above does not take in consideration b or c being zero, but for illustration it will do. |
