Allows the compiler to package individual functions in the form of packaged functions (COMDATs).
Syntax
/Gy[-]
Remarks
The linker requires that functions be packaged separately as COMDATs to exclude or order individual functions in a DLL or .exe file.
You can use the linker option /OPT (Optimizations) to exclude unreferenced packaged functions from the .exe file.
You can use the linker option /ORDER (Put Functions in Order) to include packaged functions in a specified order in the .exe file.
Inline functions are always packaged if they are instantiated as calls (which occurs, for example, if inlining is off or you take a function address). In addition, C++ member functions defined in the class declaration are automatically packaged; other functions are not, and selecting this option is required to compile them as packaged functions.
Note
The /ZI option, used for Edit and Continue, automatically sets the /Gy option.
To set this compiler option in the Visual Studio development environment
Open the project's Property Pages dialog box. For details, see Set C++ compiler and build properties in Visual Studio.
Select the Configuration Properties > C/C++ > Code Generation property page.
