[LLVMdev] incorrect DSCallGraph for simple indirect call with vtable nearby
...of the size of the analysis information (while doing interprocedural inlining) is to drop "illlegal" callgraph edges. This can be very useful in many cases, particularly at helping DSA scale on large codes that are hard to analyze. Anyway, one such arguably illegal pairing is a varargs/nonvarargs mismatch between callsite and callee, and filtering on this is what's causing the results you're seeing. To be maximally clear, DSA sees you calling a var-args method from a non-varargs callsite and says "nope, that's illegal, that can't be right" ("and if you really...

Well, that didn't take long. :-) I have found two new surprises in DSCallGraph as built by TDDataStructures. Consider the following program, which is complete and self-contained and which has one simple indirect call site: volatile int unknown; static void red() { } static void

OK, I have switched to TDDataStructures as well, and I am also seeing much better (for my purposes) results in simple tests. I'll keep poking at this some more and
