it's fun to imagine starting from scratch: writing a primitive assembler in machine code, then a primitive compiler in assembly, then slowly bootstrapping that into a complete system

on the other hand, how exactly are we writing the machine code without a computer? once upon a time i think you could toggle this stuff directly into memory using switches or something on the side of the storage system, but those days are gone. and why did They Who Done The Event wipe all the drives but not any of the firmware? maybe somebody hid a compiler in the firmware. oh, and a kernel, that would be grand

What if the firmware is OpenFirmware and you already have a nice Forth to play with?

again, totally not the use case for C (operating systems, low level programs and embedded code too big for assembly)

use java or Visual Basic or whateverthefuck

It's nothing to do with that, it's because single pass compilers were important in like 1970 because their computers were slow and had the memory of a modern microwave. Theres no real excuse for it in 2017 and it would have no effect on what actual code is generated.
