Dear All, I'm a new bee in using LLVM environment. I have certain doubts in using compiler and profiler. Please, someone explain how and why it is so? compiler: What is the default optimization level in llvm-gcc? profiler: 1. During basic block profiling why all functions are not listed. 2. In function execution frequencies, why only 6 functions are listed? 3. There is no information about main() function in profiling many of the applications. Why is it so? With Thanks, R.D.PATEL Research Scholar,E.C.E. Department MANIT, Bhopal M:(91)8085090402, H:(91)8602677554 -------------- next part -------------- An HTML attachment was scrubbed...
