Hi Jakob,

Thanks for your reviewing.
Are you suggesting to first fix the DAG framework to let it support untyped nodes, and then in ARM inline asm, we use copyToReg/CopyFromReg instead of creating virtual regs?

No, I mean the DAG for an inline asm that reads or writes a GPRPair should look like the one you already made for ldrexd/strexd.
