Summary: processFunctionBeforeCalleeSavedScan was renamed to determineCalleeSaves and now takes a BitVector parameter as of rL242165, reviewed in http://reviews.llvm.org/D10909 WebAssembly is still marked as experimental and therefore doesn't build by default. It does, however, grep by default! I notice that processFunctionBeforeCalleeSavedScan is still mentioned in a few comments and error messages, which I also fixed. Reviewers: qcolombet, sunfish Subscribers: jfb, dsanders, hfinkel, MatzeB, llvm-commits Differential Revision: http://reviews.llvm.org/D11199 llvm-svn: 242242
