Summary

Remove unused function

[lbenes]

I can confirm that gcc 10.1.1 no longer warns after this patch is applied. This fixes the issue for me.

llvm/lib/MC/MCParser/MasmParser.cpp

private:
   bool emitFieldInitializer(const FieldInfo &Field,
                             const StructFieldInfo &Contents,
                             const StructFieldInfo &Initializer);
 
   bool emitStructInitializer(const StructInfo &Structure,
                              const StructInitializer &Initializer);
 
   // User-defined types (structs, unions):
-  bool emitStructValue(const StructInfo &Structure,

   bool emitStructValues(const StructInfo &Structure);
   bool addStructField(StringRef Name, const StructInfo &Structure);
   bool parseDirectiveStructValue(const StructInfo &Structure,
                                  StringRef Directive, SMLoc DirLoc);
   bool parseDirectiveNamedStructValue(const StructInfo &Structure,
                                       StringRef Directive, SMLoc DirLoc,
                                       StringRef Name);
