8cc.js
C code
// You can run a larger C program (FizzBuzz) by changing this condition. // Note you may not want to do this for slower backends (e.g., Brainfuck). #if 1 int putchar(int c); int main() { const char* p = "Hello, world!\n"; for (; *p; p++) putchar(*p); return 0; } #else #include <stdio.h> int main() { for (int i = 1; i <= 100; i++) { if (i % 5) { if (i % 3) { printf("%d\n", i); } else { printf("Fizz\n"); } } else { printf("FizzBuzz\n" + i * i % 3 * 4); } } return 0; } #endif

"Compile" runs 8cc.js on JavaScript to generate ELVM IR.
"Assemble" runs ELVM's assembler (elc.js) for specified language. Language selection makes sense only when you assemble EIR.
"Run EIR" runs ELVM IR on JavaScript (eli.js).
"Run JS" runs "Assembled code" as JavaScript.
