Hi,
This kind of inline assembly is given in the GCC Test suits
asm ("" : "=r" (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
What will be the value of r(tmp) after this instruction.Whether it is
equivalent to
ld r2,#0x0
Thanks in advance,
Chris
