Identify virtual function call sites and candidate callees for it
...of virtual table pointers. I thought it might be useful. But still am not sure if this would be the correct way to solve the problem and even if it is how extend this approach to get information about potential callees. I would greatly appreciate any ideas or hints on how to solve these problems. Anahit. -------------- next part -------------- An HTML attachment was scrubbed...

llvm 3.9 Alias Analysis result for function's by-ref arguments
...hat this happens on purpose. llvm Alias Analysis marks function's by-ref arguments MayAlias, as function may be called with arguments referencing the same variable. So I would like to ask whether this is the case. And if it is, is there a way to make llvm ignore this consideration?

llvm MemorySSA def-use chains
Hi, I have a question about how llvm MemorySSA works, as seems I misunderstand something. Consider following code snippet and corresponding IR with MemorySSA annotations (got with opt -print-memoryssa) void foo(int* b) { int a = 0; int d = 12; if (b) { a = 42; d = 32; } int c = a; int e = d; } ; Function Attrs: noinline nounwind optnone uwtable
