Dear All Is there is a way to recompile a function at runtime? It seems that I need to -like - invalidate the recompiled function to force the MCJIT to recompile it, cause when I just call runFunction, it neglects any modifications in the function code. Thanks in advance.

Dear All Is there is a way I can get the original hogh level code (e.g c++ code) of an IR function within MCJIT?

Dear All I need to create a pass that is triggered to run at a specific point during runtime. Also, this pass needs to have access to object file and to be able to modify the original IR. Any idea how to make such pass?

Hi Marwa, MCJIT doesn't provide any support for recompilation. The best you can do is use multiple MCJIT instances and destroy whichever one contains the function "foo" that you want to recompile. MCJIT does not do any dependence tracking either, so you'll also need to destroy and recompi...

...and I really appreciate any help. I'm trying to extract variable values at interrupt of some program. And I want to do that from JIT. The situation is that the JIT will interrupt at certain point of executing some code and tries to get the variables' values. Any help about that?

...the making was successful, by just following steps 1,2 and 3. I found that one of the problems was that I modify in a wrong Passes.h, as there are 2. My question now is: How I can apply this pass? (call, use ... etc) >From what I've read I found that I can't call it from opt.

...that inserts a new basic block at the start of a loop. However when I try to change predecessor/successor relations, it does not consider the new block in the loop at all. So I got that just inserting a loop in a function before another loop is not enough. So how exactly to do this job?

...dragonegg, llgo and so. However, I've checked them and configuration went on. Now I'm stuck at build stage, specifically at dragonegg. First it could not find gmp.h, I've solved this by installing libgmp-dev. Now, it can't find auto-host.h. I couldn't solve this.

...And I tried to rebuild the llvm to make it take my pass into account. I placed my pass in the llvm/lib/CodeGen folder. But - as I predicted - it didn't work.

...re void @foo(i32 ()*, label) call: call void @foo(i32 ()* @main, label %for.cond) But when I try to run the resulting .ll file using lli, everything explodes! This the first 2 lines before the stacktrace: Can't get register for value! UNREACHABLE executed at /home/marwayusuf/llvm-env/llvm/lib/CodeGen/SelectionDAG/SelectionDAGBuilder.cpp:1158! I concluded that the problem is it can't find the foo function. If this is the problem, how can I create the callinst correctly?

This is effectively exactly what a debugger does when introspecting the state of a running program. Your JIT'ed code will need to use the program's debug information to get what it wants. -Jim On Apr 3, 2013, at 5:24 AM, marwayusuf at feng.bu.edu.eg wrote: > Dear all > I have a question and I really appreciate any help. > I'm trying to extract variable values at interrupt of some program.
