Chris Lattner 857eb0697f Fix three bugs: ... 1. Calls to external global VARIABLES should not be treated as a call to an external function 2. Efficiently deleting an element from a vector by using std::swap with the back, then pop_back is NOT a good way to keep the vector sorted. 3. Our hope of having stuff get deleted by making them redundant just won't work. In particular, if we have three calls in sequence that should be merged: A, B, C first we unify B into A. To be sure that they appeared identical (so B would be erased) we set B = A. On the next step, we unified C into A and set C = A. Unfortunately, this is no guarantee that C = B, so we would fail to delete the dead call. Switch to a more explicit scheme. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17357 91177308-0d34-0410-b5e6-96231b3b80d8		2004-10-30 05:41:23 +00:00
