[llvm-dev] Modifying Address Sanitizer

[Aayushi Agrawal via llvm-dev]

Thank you for the response.

Suppose I want to make changes in the LLVM part of Address Sanitizer.
Is there still a way to test the changes made to address sanitizer as a
standalone.

Also can a pass be run after Address Sanitizer Pass is ran, where I can
access the variables created by address sanitizer [LLVM Code] so that I
avoid making changes directly to the address sanitizer?
