You talk about "writing it in assembly language for each MPU

these modern inventions, called compilers that do that type of
work for us. They translate high level instructions, not
into assembler but into machine language.
Actually, all of the compilers I'm familiar with (gcc and a
handful of cross compilers for various microprocessors)
translate from high-level languages (e.g. C, C++) into
assembly, which is then assembled into relocatable object
files, which are then linked/loaded to produce machine
language.
I just learned something I did not know. I was under the impression that they
translated directly to machine code without ever actually generating Assembler
text files. Seems like a waste to generate the text and turn around run that
through the assembler, but what do I know. I guess that way the compiler can
have pluggable assembler back-ends.
