Description siegelords_abode 2012年01月22日 21:27:26 UTC

When compiled with dmd 2.057 on 64 bit Linux OS the following code gives an error:
void main()
{
	asm
	{
		xadd qword ptr [RAX],RDX;
	}
}
test.d(5): bad type/size of operands 'xadd'
LDC2 compiles that code fine on the same system. I don't know enough assembly to tell who is wrong.
