Subject: Show members of DeclContexts (i.e., class members) in Visual Studio native visualizers
X-Git-Tag: llvmorg-3.9.0-rc1~11463
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a814d3d288382baab2fd000a686e2c9095a4027c;p=platform%2Fupstream%2Fllvm.git

Show members of DeclContexts (i.e., class members) in Visual Studio native visualizers

This change shows members of DeclContext objects in the Visual Studio debugger. It will also cast a TagType like a class or a struct to a DeclContext, so its methods and fields are visualized.
