I never did anything like that ... but I'm trying. Look at
https://github.com/mildred/self/commits/x86_64
I don't think I'll see the same things that you did, as x86_64 is kind of
compatible with i386.

First, I plan to make the VM compile, replacing int32 to a pointer-length
integer when necessary. I hope the assembler files will compile with not too
much problems and I plan on trying to run the VM. Then, it'll probably crash
and I'll have to debug it.

Do you think the assembler files are necessary, can't they be replaced by C
files?

For sure, vmDate.s could be replaced already.
