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?)

template toInt(char[4] arg)
{
	const uint toInt = (cast(uint[]) arg)[0];
	}
	 
	 void main()
	 {
	   auto i = toInt!("abcd");
	   }
