[LLVMdev] Inserting annotations

[Gordon Henriksen]

Read about the @llvm.annotation family of intrinsics.

http://llvm.org/docs/LangRef.html#int_var_annotation

llvm::Annotatable is a deprecated means of maintaining "on the side"  
data structures internal to the compiler. Its name is misleading, and  
it has nothing to do with the sort of annotations most people are  
interested in. We would like it to go away; it is currently used only  
to attach the temporary MachineFunction data structure to a Function  
during code generation. Developers with interest Annotatable as it  
stands are advised to use a SmallPtrSet instead.
