I have a very naive question. I've written a pass that gets an argument from
the command line with the following code:
static cl::opt<int> LineNum("line-number", cl::Hidden,
cl::Required,cl::desc("line of variable being observed"));
Now when I run it, it seems like it cant see that I've put in an argument on
the command line:
opt -load /Users/sam/llvm/llvm-2.6/Release/lib/LLVMHello.dylib -hello2
which "18" is the argument. Stupidly enough I've put this argument any where
in the command line and it wont work it keeps telling me:
opt: Too many positional arguments specified!
Can specify at most 1 positional arguments: See: opt --help
opt: for the -line-number option: must be specified at least once!
Can someone please help me out. Thank you
