How much work would adding a new backend be?

[AbleTheAbove]

I have been looking for a small c compiler to hack a backend into for my bytecode virtual machine and so far most are not approachable at all..

[rofl0r]

the amount of needed code seems to be roughly 2 KLOC judging by the removal of a backend: 2a18041
now divide that linecount by your average LOC/h and you know how much work it will be.

If you're OK with everything (int, float, pointer/address) being 32-bit and smaller (16-bit and 8-bit for smaller integer types) and your architecture is sufficiently regular, it should be relatively straightforward. Look at that removed code generator mentioned above or the MIPS32 code generator (they're similar to one another). Supporting 64-bit types with the current design/implementation of SmallerC is quite hard.
