Well, it works, but then again it really does not. For example, the
original implementation doesn't even look at the alignment of var.

to have some test cases to demonstrate that the intraprocedural

That would be very nice !

L.S.,
Due to the discussion on register allocation, I went back to a hobby of
mine: Studying the assembly output of the compiler.

front end, reals are 32 bit floating point numbers):
