clang-p2996/llvm/test/Transforms/InstCombine/double-float-shrink-2.ll
Bjorn Pettersson 0676acb6fd [test] Switch to use -passes syntax in a bunch of test cases 
Should cover most of the tests for GVN, GVNHoist, GVNSink, GlobalOpt,
GlobalSplit, InstCombine, Reassociate, SROA and TailCallElim that
had not been updated earlier.
