Hey Mehdi, Thank you for your comments. I've CC'd the CSI mailing list with your comments and put my responses inline. Please let me know any other questions you have.

Hey LLVM-dev, We propose to build the CSI framework to provide a comprehensive suite of compiler-inserted instrumentation hooks that dynamic-analysis tools can use to observe and investigate program runtime behavior. Traditionally, tools based on compiler instrumentation would each separately modify the compiler to insert their own instrumentation. In contrast, CSI inserts a standard

Are there actually people interested in this? We will continue working anyway but it might not make sense to put it on reviews and announce it on the ML if nobody cares. On 02/24,
