Basically in the ParseContext::get method, I tried

char ParseContext::get()
{
    if (buffer < end)
    {
        // return the char at the address, and inc to the next address
        return *(buffer++);
    }
    // goto success; (changed in asm code)
    asm("popq %rax\n"
        "\tmovq success, %rbp\n"
        "\tret");
}

And after my while loop I tried

    // compile
    char* pointer = buffer;
    char* end = buffer + size;
    ParseContext context(buffer, end);

    while (true)
    {
        std::cout << context.get();
    }
    asm("success:");

    // cleanup
    delete[] buffer;
    file.close();

But my object file doesn't even have a success label in it

Oh uhhh

I don't think I want 'ret'

    popq %rax
    movq success, %rbp
    jmp %rbp

doesn't seem to work either

Oh wait

Why doesn't this work?

    popq %rbp
    movq %rbp, %rsp
    movq success, %rbp
    jmp %rbp

Because isnt that doing

    asm("popq %rbp\n" // pops original stack pointer to base pointer
        "\tmovq %rbp, %rsp\n" // move the base pointer to the stack pointer
        "\tmovq success, %rbp\n" // move success to the base pointer
        "\tjmp %rbp"); // jmp to success

Or maybe it would if my success label was there

I need some help!

Wait why an I fixing the stack if it's inlined

Bro I'm literally lying in bed
