Why does gas put a stop bit in a bundle?

["H. J. Lu" <hjl at lucon dot org>]

GAS adds a stop bit at the last bundle in the current section
automatically.

# gcc -c -o gcc.o bundle.s
# objdump -d gcc.o 
gcc.o:     file format elf64-ia64-little
 
Disassembly of section .text:
 
0000000000000000 <.text>:
   0:   0d 40 00 40 18 10       [MFI]       ld8 r8=[r32]
   6:   00 00 00 02 00 00                   nop.f 0x0
   c:   00 00 04 00                         nop.i 0x0;;
  10:   0d 30 00 04 18 10       [MFI]       ld8 r6=[r2]
  16:   00 00 00 02 00 00                   nop.f 0x0
  1c:   00 00 04 00                         nop.i 0x0;;

Why does gas do that? I'd like to turn it off.
