[LLVMdev] outlining in llvm

[Bataev, Alexey]

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,
Alexey Bataev
