Hi,

This kind of inline assembly is given in the GCC Test suits

asm ("" : "=3Dr" (tmp) : "0" (tmp));

As per my understanding the input and output remains in the same
register.But there is no instruction in the first double coats("").

The Question is=20

What will be the value of r(tmp) after this instruction.Whether it is
equivalent to

ld r2,#0x0

Thanks in advance,
Chris
