2004-03-13This change makes two big adjustments.Chris Lattner
* Be a lot more accurate about what the effects will be when inlining a call to a function when an argument is an alloca. * Dramatically reduce the penalty for inlining a call in a large function. This heuristic made it almost impossible to inline a function into a large function, no matter how small the callee is. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12363 91177308-0d34-0410-b5e6-96231b3b80d8
2004-03-13This little patch speeds up the loop used to update the dominator set analysis.Chris Lattner
On the testcase from GCC PR12440, which has a LOT of loops (1392 of which require preheaders to be inserted), this speeds up the loopsimplify pass from 1.931s to 0.1875s. The loop in question goes from 1.65s -> 0.0097s, which isn't bad. All of these times are a debug build. This adds a dependency on DominatorTree analysis that was not there before, but we always had dominatortree available anyway, because LICM requires both loop simplify and DT, so this doesn't add any extra analysis in practice. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12362 91177308-0d34-0410-b5e6-96231b3b80d8
