Can anyone tell how changing the optimization levels ( -O) in llvm changes
if the arguments are passed to a function by value or by reference? For
example if we pass an argument by value to a function can changing the
optimization level can force it to be pass by reference if at all it makes
the code optimized in some way. Please guide.
