[cfe-dev] CodeGen and AnnotateAttr objects

[Mark Brown]

I'm trying to figure out how Clang's CodeGen deals with AnnotateAttr
objects. The only uses of "AnnotateAttr" I can find in the CodeGen directory
seem to point to CodeGenModule::EmitAnnotateAttr(). The comment here seems
to imply that this function will only handle AnnotateAttrs on GlobalValues.

How/where does it handle AnnotateAttrs on VarDecls, or even regular Decls?
I'm asking because I have added some AnnotateAttrs to VarDecls in a plugin,
had that plugin write out its AST file and then let clang compile it(with -S
-emit-llvm). There was no references to my string(used in the AnnotateAttrs)
or even of something like @llvm.var.annotation. So for some reason they are
not making it to the IR and I have no idea why.

Thank you
