[llvm-commits] [PATCH] Support for multi-valued options in CommandLine

[Mikhail Glushenkov]

Hi,

this adds support for multi-valued options to CommandLine (needed to  
implement some Darwin-specific options in llvmc).

Used like this:

// Zero or more occurences, 2 values
cl::list<std::string> MultiValuedOption("multi-valued", cl::multi_val(2));

// One and only one occurence, 3 values
cl::list<std::string> MultiValuedOption("multi-valued",  
cl::multi_val(3), cl::Required);
