(original) (raw)

I am PhD student. My work deals with finding the memory (RAM) consumption as indicated by linux RSS output and execution time as indicated by linux time command at compile time using LLVM. How can I do this? Like if i pass dataset size and application to llvm compiler, it should tell the estimated memory consumption and time taken to execute given application with given dataset, but all at compile time? I am trying to avoid profiling here. I wont get accurate values, hence rough estimated values of memory consumption and time are enough...

Can llvm-mca help me in finding these statistics? or I need to write a new compiler analysis pass to find these values?

Please help how to proceed.

Thank You
