llvm dev - Aug 2004 - [LLVMdev] How could I get memory address for each basic block?

On the pervious mail, I am trying to add label for each basic basic because I
think I could get address by using nm if nm can show the address of each label,
but it seems not . so do you guys have some idea how to get address for each
basic block? Thanks.

Thanks for any >response.

LLVM does not have a notion of C-style 'labels' that you can address and
use as parameters.  LLVM labels are simply NAMES of basic blocks, and
they are printed out as `labels'.

You can 'set' a name for a BasicBlock, but that's not what you are
looking for, please see my other email for more details.

Qiuyu,

The dynamic optimization project (an internal research project in our 
group) uses some way to map LLVM basic blocks to native code addresses. 
  If this is what you want, perhaps you can ask Brian Gaeke 
(gaeke at uiuc.edu) to give you some information about how that is done.
