Re: Conditional Compilation support in INF file

["Gao, Liming" <liming.gao@intel.com>]

I have same question. What flexibility is expected in INF? I see one request in [Depex] section. So, PCD support in [Depex] is added. 

Edk2 INF is used to describe the source code behavior. If the source uses Ppi/Protocol/Guid/Pcd, these information are always required to be described in INF file. The compiler can optimize the code and remove the unused Ppi/Protocol/Guid/Pcd. It doesn't need developer specify the conditional statement. 

Thanks
