When transforming a call to a bitcast function into a direct call with cast parameters and cast return value (if any), instcombine was prepared to cast any non-void return value into any other, whether castable or not. Add a new predicate for testing whether casting is valid, and check it both for the return value and (as a cleanup) for the parameters. llvm-svn: 45657 2008-01-06 18:12:28 +08:00
