Matthijs Kooijman 477f5a2f11 Restructure ArgumentPromotion a bit. Instead of just having a single boolean ... that says "unconditional loads from this argument are safe", we now keep track of the safety per set of indices from which loads happen. This prevents ArgPromotion from promoting loads that aren't really valid. As an added effect, this will now disregard the the type of the indices passed to a GEP, so "load GEP %A, i32 1" and "load GEP %A, i64 1" will result in a single argument, not two. This fixes PR2598, for which a testcase has been added as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54159 91177308-0d34-0410-b5e6-96231b3b80d8		2008-07-29 10:00:13 +00:00
