Repeated calculation of angr CFGFasr leads to low running efficiency and high memory consumption when there are too many function

[xzjpgithub]

in AngrAnalysis.init() self.cfg = self.target.analyses.CFG( resolve_indirect_jumps=True, cross_references=True, force_complete_scan=False, normalize=True, symbols=True, )

the edges of functions is already in self.cfg the way to get edges of function are followings

for func in self.cfg.functions.values(): print(func.addr, len(func.transition_graph.edges))

so I think the code of function get_cyclomatic_complexity(),

cfg = self.target.analyses.CFGFast( force_complete_scan=False, start_at_entry=hex(func.addr) )

This code uses CFGFast to recalculate edges for each function. Leading to low running efficiency and high memory consumption when there are too many function.

Can we optimize this ：)
