Could someone help me?
How can I determine (or where are) the use-definition chains
in the sources of the gcc?
Or, more generally: How can I know if one statement in the
RTL linked list is dependent one another via data dependence??
Thanks very much.
M. Buss.

You may want to look at LOG_LINKS which is set up by life_analysis
and used by the combiner.
