Ah, sorry, my memory was wrong. The default is to perform the "SelectivePA" optimization. Since pool allocation detected that there is no point in putting a single allocation into a pool, it left it a malloc. If you really want it to be a in a pool, pass -poolalloc-heuristic=AllNodes to opt. Sorry for the confusion! -Chris > I am using this line: > opt -...

Thanks for the answer I am trying to test the PA with a program very similar to the one used as an example in the paper located here: http://llvm.cs.uiuc.edu/pubs/2003-04-29-DataStructureAnalysisTR.html The program is as follows: ========================== struct list { struct list *Next; }; struct list *makeList (int Num) { struct list *New = malloc ( sizeof ( struct list ) );
