[LLVMdev] LVLM runtime optimization during LLVM Analysis Passes.

[Sri]

Hi Philip
            I understood what you have said here. Basically you are 
saying , identifying the hot path during the runtime and compile those 
section again would be hard in llvm-IR. I am currently looking forward 
to do some analysis work on adaptive mechanism for llvm JIT so that , we 
can see some improvement when we see that high frequent function call 
during the run time. Do you have any idea , which approach would be more 
convenient to start this work.
Thanks.

Regards
Sri.
