I don't know about TinyCC's internals but RV64 and RV32 are very similar. There 
are only a couple of opcodes that change and some instructions (loads and 
stores) have to be adjusted but that's most of it.

In some months I should be reading tinycc's internals so I could give a better 
answer or even implement this myself but I can't promise anything at the moment.
