Change live interval representation. Machine instructions now have two slots each. As a concequence they get numbered as 0, 2, 4 and so on. The first slot is used for operand uses and the second for defs. Here's an example:
Change live interval representation. Machine instructions now have two
slots each. As a concequence they get numbered as 0, 2, 4 and so
on. The first slot is used for operand uses and the second for
defs. Here's an example:

0: A = ...
2: B = ...
4: C = A + B ;; last use of A

The live intervals should look like:

A = [1, 5)
B = [3, x)
C = [5, y)
