- Program can be validaded either before execution or when executing
# Traps
| Name | Parameters | Cause |
|:-------------:|:----------------:|:--------------------------:|
| LoadAccessEx | Accessed address | Loading invalid address |
| StoreAccessEx | Accessed address | Storing to invalid address |
| InvalidOpcode | Loaded opcode | Executing invalid opcode |
| Ecall | None | Ecall instruction |
Program should at least implement these traps:
- Environment call
- Invalid instruction exception
- Load address exception
- Store address exception
and executing environment should be able to get information about them,
like the opcode of invalid instruction or attempted address to load/store.
Details about these are left as an implementation detail.
