PowerPC was designed as a 64-bit specification with 32-bit implementations, and not only that, PowerPC user-level programs are more or less binary-compatible across those implementations. Not using c-libraries is a somewhat strange. Generally this takes two syscalls: write and exit. arduino-hello-world. 1)You cannot write extended toplevel inline assembly, ie when you want to use extended inline assembly to pass the value of some C variables or constants, you can only do it inside a function. figure : hello. /hello World Hello, World!
