[llvm-dev] status of msp430?

[Andrew Kelley via llvm-dev]

Hello,

I have a user asking about msp430 support for Zig. When they try to target
msp430, this error is triggered:

        if (target_machine->addPassesToEmitFile(MPM, dest, ft)) {
            *error_message = strdup("TargetMachine can't emit a file of
this type");
            return true;
        }

I tried using clang alone: clang -c add.c -target msp430-unknown

int add(int a, int b) {
    return a + b;
}


$ clang -c add.c -target msp430-unknown

Is msp430 supported?
