Compiler for a simple programming language named harakiri to an assembly. It's implemented without LLVM or GCC backend.
- Aarch64
All supported constructions are used in the code below:
def fib(n) {
if n <= 2 {
return 1
}
return fib(n-1) + fib(n-2)
}
def print_interval(from, to) {
while from < to {
echo(from)
from = from + 1
}
}
def main() {
echo("Enter mode: 0 - interval printer, 1 - fibonacci calculator")
a = -1
while 1 {
a = input()
if a != 0 && a != 1 {
echo("Mode must be equal to 0 or 1")
} else {
break
}
}
if a == 0 {
echo("enter start value")
a = input()
echo("enter end value")
b = input()
print_interval(a, b)
} else {
echo("enter n to get n-th fibonacci number")
a = input()
echo(a, "-th fibonacci number is: ", fib(a))
}
}
