The .code16gcc directive was added to binutils back in 1999:

---
   '.code16gcc' provides experimental support for generating 16-bit code
from gcc, and differs from '.code16' in that 'call', 'ret', 'enter',
'leave', 'push', 'pop', 'pusha', 'popa', 'pushf', and 'popf'
instructions default to 32-bit size.  This is so that the stack pointer
is manipulated in the same way over function calls, allowing access to
function parameters at the same stack offsets as in 32-bit mode.
'.code16gcc' also automatically adds address size prefixes where
necessary to use the 32-bit addressing modes that gcc generates.
---

It encodes 32-bit assembly instructions generated by GCC in 16-bit format
so that GCC can be used to generate 16-bit instructions.  To do that, the
.code16gcc directive must be placed at the very beginning of the assembly
code.  This patch adds -m16 to x86 backend by:

1. Add -m16 and make it mutually exclusive with -m32, -m64 and -mx32.
2. Treat -m16 like -m32 so that --32 is passed to assembler.
3. Output .code16gcc at the very beginning of the assembly code.
4. Turn off 64-bit ISA when -m16 is used.
