AbstractVM is a stack machine that evaluates simple arithmetic expressions. These expressions are supplied to the machine by programs written in a language similar to the assembler.
| Instruction | Description |
|---|---|
| push "Value" | Push the value "Value" |
| pop | Pop a value from the top of the stack |
| add | Pop two values a and b, calculate the sum b + a, and push the result into the stack |
| sub | Pop two values a and b, calculate the difference b - a, and push the result into the stack |
| mul | Pop two values a and b, calculate the product b * a, and push the result into the stack |
| div | Pop two values a and b, calculate the quotient b / a, and push the result into the stack |
| mod | Pop two values a and b, calculate the modulo b % a, and push the result into the stack |
| assert "Value" | Check if the top value of the stack is equal to "Value" |
| dump | Pritnt all the content of the stack |
| Check if the top value of the stack is of int8 type, and print the corresponding ASCII code | |
| exit | Exit the program |
