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
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.
