Hi! In some cases the use of blockaddress() crashes llc. I've attached two test-cases, one that crashes and for reference a slightly modified one (just 2 lines are commented) that works.

Hi Brenda, you can bitcast a BlockAdress to an intptr and then manipulate it as you want. Unfortunately, there' is no guarentee that you can do anything appart jumping to this adress from the same function, as described in the langref http://llvm.org/docs/LangRef.html#addresses-of-basic-blocks This value only has defined behavior...

Hi all, I have a question concerning block address class in LLVM. I am currently working on a project where I need to obtain and manipulate basic block virtual addresses. I was searching the web and found the llvm::BlockAddress class (http://llvm.org/doxygen/classllvm_1_1BlockAddress.html). With this class I was able to obtain a printout like this: i8* blockaddress(@func_name, %bb_label) How do
