This is a simple example of Proteus processing. Note that the ll file is provided so you may skip the production of this.

Produce the ll file

Below is a simple c program that generates numbers in the fibonacci series (src)
/* Simple Program to generate fibonacci numbers */ #include <stdio.h> int main(int argc, char * argv[]) { int n; int i; int current; int next; int sum; printf("How many Fibonacci numbers do you want to calculate? "); scanf("%d", &n); if (n<=0) printf("The number should be positive.\n"); else { printf("\n\tI \t Fibonacci(I) \n\t=====================\n"); next = current = 1; for (i=1; i<=n; i++) { printf("\t%d \t %d\n", i, current); sum = current+next; current = next; next = sum; } } }
Using the below command line the ll file was generated
llvm-gcc fibonacci.c -S --emit-llvm -o fibonacci.ll

Compile with Proteus

Now using this ll file generate an executable jar

To generate a jar in the current directory which contains all necessary classes
java -jar Proteus.jar fibonacci.ll

Run the generated java executable

java -jar fibonacci.jar
