Update comments now that LLVM PR3861 has been fixed. However, since conditionally removing the workaround makes the ABI dependent on LLVM version, I reconsidered that. (The same revision of LDC compiling for the same target should probably produce code that follows the same ABI, right?)

module alignment;

align(1) struct S
{
    ubyte b;
    int i;
    ubyte[2] b2;
    long l;
    real r;
}

void main()
{
    byte b;
    short s;
    int i;
    long l;
    float f;
    double d;
    real r;
}
