[Soot-list] Problem with flow analysis

[Joe Qian]

Hi,
I have read the tutorial about doing flow analysis using soot. It seems
that the two flow analysis classes, /ForwardFlowAnalysis/ and
/BackwardFlowAnalysis, /can only be used when both the kill set and the
generate set do not vary during the iterative computing of IN set and
OUT set on the control flow graphs. Is there any easy way to add a hook
for recomputing such sets when necessary?
Thanks.
