...i<num; i++) { sum += getV(i); } return 0; } -------------------------------------------------------- 2. Then, I translated it to LLVM bitcode by: llvm-gcc -emit-llvm -c test.c 3. Then, I performed some optimization passes as: opt -loop-rotate -loops -loopvr -indvars -loopsimplify -f < test.o > n.o 4. I tried to dump the loop trip count by my own pass (cfginst): opt -load lib/libLLVMCFGInst.so -cfginst < n.o ----------------------------------------------- But I got the following messages: Function getV doesn't have loops Function main h...

Hi Ryan, In this case there already is an implementation for this, it's just hard to find being in the internals of the LoopVR pass. I'm planning to pull the multiply and udiv support out of there. Your patch looks good but beyond what Dan mentioned you have a bug calculating NewUpper: the constant ranges are half-open intervals where "[5, 10)" includes the value 9 but not 10. This means you need to subt...

Thanks a lot for your guys' help!!! I guess once I am able to get *V* (which probably is a pointer to a Value object), then, I can instrument some code at the IR level to dump V. As long as I maintain V at this pass stage, I should be able to dump the loop trip count. This is true, isn't it? Basically, what I am going to do is to add a function call before the loop body, such as:

Hi, I was working on alias analysis using LLVM-2.6 previously. But I just downloaded LLVM-2.7 and found AndersenAA is not there. What happened for andersen's IPA alias analysis? Has it been deleted for some reason? Thanks. Lei -------------- next part -------------- An HTML attachment was scrubbed... URL:
