Hi Tehila,
You can try to use function outlining implemented in clang. It is based on class CapturedStmt.
You can try it with the the following construct:
#pragma clang __debug captured
<Code to be outlined>
Implementation is in clang/lib/Parse/ParsePragma.cpp, StmtResult Parser::HandlePragmaCaptured()
Best regards,

Hi,
I have some questions regarding outlining (extracting piece of code into a function):
1. Is there an outlining pass in llvm (IR)? I've found out CodeExtractor pass, but I'm not sure it’s exactly the same idea.
2. How do I set the function name?
And another question:
Where do I control the execution of my pass? I'm writing a pass that first works on loops, than on a function (outlined from the loop) and then again on loops.
How can I do that?
Thanks and happy new year,
Tehila.
