[cfe-commits] [PATCH] Explicitly Build __builtin_va_list

[Inge, Meador]

Hi All,

As discussed here [1], I have been working on a patch to explicitly build the target specific __builtin_va_list type instead of just injecting a string into the preprocessor input.  This will provide a cleaner separation between preprocessor input and builtin types, will allow us to remove the special casing in 'Sema::ActOnTypedefNameDecl' to notify the AST context of __builtin_va_list, and will allow us to remove the extra tracking added for PR 12665 in r158085.

OK to commit?  If this is accepted, I will go backout the tracking portions of r158085 in another commit.
