Hi, I tried to use the LiveValues pass without success. I did exactly as you wrote me but no luck for me. I am getting this error : [rotem at localhost ~]$ opt -load /home/rotem/Desktop/install/Release/lib/BBPass.so -BBPass < /home/rotem/Desktop/tmp/BBtry.bc > /dev/null Error opening '/home/rotem/Desktop/install/Release/lib/BBPass.so': /home/rotem/Desktop/install/Release/lib/BBPass.so: undefined symbol: _ZN4llvm10LiveValues2IDE -load request ignored. opt: Unknown command line argument '-...

Yes; it's a standard analysis pass. See http://llvm.org/docs/WritingAnLLVMPass.html for information about interactions between passes. > How do i get/use the

Hi, I need the Instructions live out, so i will be able to run my pass. One option that i already discussed is to compute it myself. Second option, use the LiveValues Pass(include/llvm/Analysis/LiveValues). This questions are on the LiveValues pass: Do i need to set the "LiveValues" pass in the PassManager as a prerequisite? if so how do i get the results ?How do i get/use the results

The patch below basically hammers out some ideas as to where I'd like to take the passmanager in LLVM. I've tried thinking things through, but I'm still a n00b, so some criticism would be more than welcome. =) Starting from line 191 down. If you're wondering why I created a patch, well that's because I found thinking in passmanagert.h the most productive. -- Regards.
