word register 0 refers to the first 8 bytes of the dynamic array. Hence the used counter should be at least 8 bytes. This deals with those issues. Also print more useful information in vm_print_registers (how many byte|hword|word registers are currently in use, how many are available).
Oreo's Virtual Machine (OVM)
A stack based virtual machine in C11. Deals primarily in bytes, doesn't make assertions about typing and is very simple to target.
Instructions to target
You need to link with the object files for
base.c, darr.c and
inst.c to be able to properly target the OVM.
The basic idea is to create instructions via inst_t then using the
inst(s)_write_* API to generate bytecode (and write to a file).
Then to execute the program, the virtual machine interpreter ovm.out
is used.
For clarity, one may build lib (make lib) then use the resulting
object files to link and create bytecode for the virtual machine.
