options. This commit changes the command line arguments (PassInfo::PassArgument) of two passes, MachineFunctionPrinter and MachineScheduler, to avoid collisions with command line options that have the same argument strings. This bug manifests when the PassList construct (defined in opt.cpp) is used in a tool that links with codegen passes. To reproduce the bug, paste the following lines into llc.cpp and run llc. #include "llvm/IR/LegacyPassNameParser.h" static llvm:🆑:list<const llvm::PassInfo*, bool, llvm::PassNameParser> PassList(llvm:🆑:desc("Optimizations available:")); rdar://problem/19212448 llvm-svn: 224186
