2004-10-30Fix three bugs:Chris Lattner
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

* change some uses of NH.getNode() in a bool context to use !NH.isNull() * Fix a bunch of places where we depended on the (undefined) order of evaluation of arguments to function calls to ensure that getNode() was called before getOffset().

2004-10-12This nutty patch has been in my tree since before 1.3 went out, and it needsChris Lattner
to go in. This patch allows us to compute the trip count of loops controlled by values loaded from constant arrays. The cannonnical example of this is strlen when passed a constant argument: for (int i = 0; "constantstring"[i]; ++i) ; return i; In this case, it will compute that the loop executes 14 times, which means that the exit value of i is 14. Because of this, the loop gets DCE'd and we are happy. This also applies to anything that does similar things, e.g. loops like this: const float Array[] = { 0.1, 2.1, 3.2, 23.21 }; for (int i = 0; Array[i] < 20; ++i) and is actually fairly general. The problem with this is that it almost never triggers. The reason is that we run indvars and the loop optimizer only at compile time, which is before things like strlen and strcpy have been inlined into the program from libc. Because of this, it almost never is used (it triggers twice in specint2k). I'm committing it because it DOES work, may be useful in the future, and doesn't slow us down at all. If/when we start running the loop optimizer at link-time (-O4?) this will be very nice indeed :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16926 91177308-0d34-0410-b5e6-96231b3b80d8
