An embeddable implementation of the Ngaro Virtual Machine for Go programs

ngaro's Issues

vm: remove Image type and rename Instance.Image to Mem

asm: support string literals in .dat

something like

.dat "hello"

with automatic 0 termination.

Use a delegate config struct for Option

vm.Option directly set Intsance fields, which is bad, it should use a delegate config structure.

With the recent addition of Ticker where using Option would be safe, we need cater for most use cases
before switching to a cfg struct.

For example, a ticker function might need to remove itself, or change the tick interval.

Also need to provide more control over the instance to Go code running it.

vm: field Intsance.Tos should be turned into a getter/setter pair

External code cannot write freely to Instance.Tos because of stack underflow protection that mandates that TOS be 0 if stack depth = 0, so writing must be done via a setter (that's why access to NOS was a getter function in the first place).

vm: change Cell type to int

Support for both 32/64 bits target by just recompiling for the proper target.

Need to add support in cmd/retro for loading 32 bits images on amd64.

vm: improve test coverage
