...3. Therefore I wrote a quick patch to make poolalloc 3.2 compile with llvm 3.3 (mostly adaptions to file relocations were necessary). The patch is attached as it is quite small. With the foundations working a simple test before getting serious seemed to be a good idea. So I tried to perform the LocalAnalysis (LocalDataStructures pass in poolalloc) on the running example (LLVM-IR obtained by clang) of Chris Lattner's PHD thesis (p. 44) (code attached). When this pass(LocalDataStructures) is run I can call dumpCallGraph() on it and get the correct result. But calls to hasDSGraph(const Function &...

...alysis in Almost Linear Time" by Steens , your PHD thesis and SteensGaard.cpp in LLVM this afternoon. So I think: 1. Actually the basic algorithm described originally by SteensGaard does not provide MOD/REF information for functions. 2. The context insensitive part of Data Structure Analysis (LocalAnalysis) can be deemed as an enhancement of Steens' with field sensitive and MOD/REF information 3. The implementation of -steens-aa in LLVM is through Data Structure Analysis with MOD/REF logic for functions as below: i. inComplete nodes may MODREF by all function. ii. external function do...
