llvm dev - Mar 2009 - [LLVMdev] Inserting annotations

Hello together,

how can i insert annotations in IR ?

I want actually write something like:
CallInst *call = CallInst::Create( ??? , aBasicBlock);

in my pass.


Regards
Raad

See http://llvm.org/docs/LangRef.html#int_annotation.

It's illegal to take the address of a basic block in LLVM IR.

Hi,

As far as I know, Instruction class does not inherit "Annotable"
Class. Only
Function inherits annotable according to the documentation of annotable
class.

What you are asking would require adding annotations at instruction level,
which does not seem to be possible. You can maintain external maps between
instructions and your annotations,

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.
