Is there any documentation on inline assembly syntax for gcc?

regards,

There's a few morsels of inline assembly documentation in the gcc
manual, in the section
  Assembler Instructions with C Expression Operands
  http://www.delorie.com/gnu/docs/gcc/gcc_86.html
.
Please tell me if you find anything better.

tmp will be unchanged from whatever was in it before.  TGhe "0" is a constraint 
saying tmp should start out in the same register as the result of that asm.

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
