I am trying to implement if-conversion as an LLVM pass. My reference is Chapter 7 of the book ""Optimizing Compilers for Modern Architectures", based on the suggestion here: https://groups.google.com/d/msg/llvm-dev/FlDGnqSGbR8/eH5hO9IBbXYJ Some steps in the if-conversion pass require simplification of Boolean Expressions. Is this doable within the LLVM API? llvm::ConstantExpr seems like the data structure to use, but I haven't found a way to simplify a value represented by a ConstantExpr. Thanks for any advice you m...

...me if there is any way to make If conversion work on programs like this. Below is an older message from 2013 about the status of if conversion from LLVM at that date (from http://lists.llvm.org/pipermail/llvm-dev/2013-November/067427.html or https://groups.google.com/forum/#!msg/llvm-dev/FlDGnqSGbR8/YZUN3h4IzA8J ). > Hi Rob, > > I chose to answer on the list since from time to time people come back > to this. > > That said, I did implement the generic variant of if-conversion that is > called "control-flow to data-flow conversion" as a basis for SIMD >...
