Paulo,
GCC schedule is not particularly designed for VLIW architectures, but it
handles them reasonably well. For the example of your code both schedules take
same time to execute:
38: 0: r1 = e[r0]
40: 4: [r0] = r1
41: 5: r0 = r0+4
43: 5: p0 = r1!=0
44: 6: jump p0
and
38: 0: r1 = e[r0]
41:
Let me add to my own post saying that it seems that the problem is that the
list scheduler is greedy in the sense that it will take an instruction from the
ready list no matter what when waiting and trying to pair it with later on with
another instruction might be more beneficial. In a sense it
