Hello, Is there currently a way to set options, like -time-passes or -regalloc from C++? I looked at the code in lib/Support/CommandLine.cpp, but the stuff that comes closest to providing such functionality (mostly GetOptionInfo()) is marked static. Thanks, Paul

You can manipulate the command-line you pass to llvm::cl::ParseCommandLineOptions; other than that, there isn't any easy way to do it. Patches to expose functionality using an option into the C++ API are generally welcome if they are clean. In an ideal world, I guess we...

...Error: Argument 'machine-licm' defined more than once! > ellsif: CommandLine Error: Argument 'machine-licm' defined more than once! I recently had a similar problem when I wrote a new pass and built it into opt. This error message is confusing because the code that prints it, in GetOptionInfo() in lib/Support/CommandLine.cpp: cerr << ProgramName << ": CommandLine Error: Argument '" << OptionNames[0] << "' defined more than once!\n"; should be printing OptionNames[i], not OptionNames[0]. (Once I had fixed this, i...

I'm linking a program (my ellsif driver) that basically brings in most of the LLVM stuff: bitcode reading, optimizations, linking, and target code generation. All of a sudden, I'm getting the following when I run: [~/elsa/ellsif] dev% ./ellsif -v test/ofmt.i test/sieve.i -time-actions -O5 <premain>: CommandLine Error: Argument 'machine-licm' defined more than once!

...ts? >From looking at the code and debugging, it appears that the call to Clang.ExecuteAction(*Act) the second time around causes llvm::cl::RegisteredOptionList (from lib/Support/CommandLine.cpp) to contain a huge (unbounded?) number of nodes. This becomes an issue when the list is processed in GetOptionInfo(). Any ideas?
