You can take a look at the other backends (*gen.c, *link.c) for how this is done in tcc. As you can see in i386-gen.c, the code generator can be done in ~852 LOC for x86. It's probably useful to start with the assembler (asm), linker (link) first. For the corresponding ISA documentation you could use when adding it, see [1], [2].
