How to make the objdump disassembled code work with gas?

[Peng Yu]

I got the following intel syntax assembly code.

$ objdump -w -d -M intel -- 1.o
...
   0:	0f 1f 44 00 00       	nop    DWORD PTR [rax+rax*1+0x0]

When I try to use the same code with gas, it shows the following
error. How to make it work?

$ cat 2.asm
.intel_syntax
nop    DWORD PTR [rax+rax*1+0x0]
$ as 2.asm
2.asm: Assembler messages:
2.asm:2: Error: invalid operands (*UND* and *ABS* sections) for `*'
