Patch from Preston Briggs <preston.briggs@gmail.com>. This is an updated version of the dependence-analysis patch, including an MIV test based on Banerjee's inequalities. It's a fairly complete implementation of the paper Practical Dependence Testing Gina Goff, Ken Kennedy, and Chau-Wen Tseng PLDI 1991 It cannot yet propagate constraints between coupled RDIV subscripts (discussed in Section 5.3.2 of the paper). It's organized as a FunctionPass with a single entry point that supports testing for dependence between two instructions in a function. If there's no dependence, it returns null. If there's a dependence, it returns a pointer to a Dependence which can be queried about details (what kind of dependence, is it loop independent, direction and distance vector entries, etc). I haven't included every imaginable feature, but there's a good selection that should be adequate for supporting many loop transformations. Of course, it can be extended as necessary. Included in the patch file are many test cases, commented with C code showing the loops and array references. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165708 91177308-0d34-0410-b5e6-96231b3b80d8

This patch implements ProfileDataLoader which loads profile data generated by -insert-edge-profiling and updates branch weight metadata accordingly. Patch by Alastair Murray. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162799 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-04New BranchProbabilityInfo analysis. Patch by Jakub Staszak!Andrew Trick
BranchProbabilityInfo provides an interface for IR passes to query the likelihood that control follows a CFG edge. This patch provides an initial implementation of static branch predication that will populate BranchProbabilityInfo for branches with no external profile information using very simple heuristics. It currently isn't hooked up to any external profile data, so static prediction does all the work. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132613 91177308-0d34-0410-b5e6-96231b3b80d8

Modified patch by Adam Preuss. This builds on the existing framework for block tracing, edge profiling and optimal edge profiling. See -help-hidden for new flags.

boolean values were distinguishable from integers. The attached patch introduces "typedef int LLVMBool;", and uses LLVMBool instead of int throughout the C API, wherever a boolean value is called for."
