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?
