Thanks John. I appreciate your help and I look forward to obtaining the code. A proper LLVM sub-project: No rush on this and please take your time.

Hello John et al - I have been struggling to implement static backwards slicing with LLVM. After digging llvmdev postings for some time, I see that other people were having similar difficulties and John's got almost complete code that may be shared. May I get a copy of it, too? Better yet, it would be helpful for many other people if the code were checked in to an example directory or

Hi, I'm trying to implement a module pass as a share object to process an entire program as a unit. The target program is built from multiple object files, hence multiple bitcode files. However, it seems that opt does not take the whole program, but just one bitcode file, "test.bc" in the example run shown below. $ opt -load mypass.dylib -mymodulepass < test.bc > /dev/null

Hello, My opt plugin contains multiple passes in it and each pass produces some results and saves them in a global data structure. $ opt -load myplugin.dylib -pass1 -pass2 -pass3 test.bc After all passes finish running, I need to flush out the collected results to a disk file. But I don't know when I can do it. Is there a way/callback for my plugin to know when opt is done with it?
