Note: Using the − s Option With the Optimizer
Optimization makes normal source interlisting impractical because the opti-
mizer extensively rearranges your program. When you use the
− s option, the
optimizer writes reconstructed C statements. The comments also include a
list of the allocated register variables. Occasionally the optimizer interlist
comments may be misleading because of copy propagation or assignment
of multiple or equivalent variables to the same register.
