[LLVMdev] Unexpected DSAnalysis behavior
...ior of our automatic parallelization framework, I found some, at least for me, unexpected behavior of the DataStructureAnalysis in Poolalloc. Consider the following simplified program: ==================== int ARR[4] = {1, 2, 3, 4}; int a(int pos) { return ARR[pos]; } int sum(int op_a, int op_b) { return a(op_a) + a(op_b); } int main(int argc, const char *argv[]) { return sum(1, 3); } ==================== The unexpected behavior is that the bottum-up-graphs (and consequently the top-down-graphs) of methods sum and main do not contain any hint on the read of the global variable A...
