[kaniandr]

Summary

This fixes problem when using FilteredPassNameParser. It inherits PassNameParser which has no default constructor. However, PassNameParser has constructor with one argument (cl::Option) which can be used.

include/llvm/IR/LegacyPassNameParser.h

 /// true for passes to be registered as command-line options.
 ///
 template<typename Filter>
 class FilteredPassNameParser : public PassNameParser {
 private:
   Filter filter;
 
 public:
+  FilteredPassNameParser(cl::Option &O) : PassNameParser(O) {}
+
   bool ignorablePassImpl(const PassInfo *P) const override {
     return !filter(*P);
   }
 };
