Hello, I'd be interested in knowing which pass performs loop inversion, i.e. transforms while loop into do/while wrapped with if. So, it's pretty easy to understand concept, http://en.wikipedia.org/wiki/Loop_inversion provides description of how its done and motivation, googling gives several relevant references, i.e. it's pretty settled term. I also see this transform to be actually performed on trivial strlen function by clang -O2. However opt --help or grepping LLVM doesn't give any hints. However,...
