Hi, this is the fourth in a series of patches to cleanup and improve the LLVM Profiling Infrastructure. It depends on the previous patches from http://lists.cs.uiuc.edu/pipermail/llvmdev/2009-July/023569.html http://lists.cs.uiuc.edu/pipermail/llvmdev/2009-July/023602.html http://lists.cs.uiuc.edu/pipermail/llvmdev/2009-July/023642.html This patch introduces an implementation of the ProfileInfo that estimates a profile as proposed in [Ball94]. (It distributes incoming flow in an block equally to the successor edges and assumes an loop iteration count of 10.) A...

Hi Andreas, First, thanks again for undertaking this work and submitting it back. There is a lot of good stuff here and it would be great to see it get back into the tree. I have a few major high-level comments on the patch. First off, the patch is quite large and should be broken down into separate incremental changes which are easier to review and apply. I think the patches should more or less

Hi all, as proposed in http://lists.cs.uiuc.edu/pipermail/llvmdev/2009-February/020396.html I implemented the algorithm presented in [Ball94]. It only instruments the minimal number of edges necessary for edge profiling. The main changes introduced by this patch are: *) a interface compatible rewrite of ProfileInfo *) a cleanup of ProfileInfoLoader (some functionality in ProfileInfoLoader
