Another example:

[hjl@gnu-cfl-3 pr31323]$ cat y.s
        xorq $0xe0, foo(%eax,%edx), %rdx
[hjl@gnu-cfl-3 pr31323]$ make y.o
./as   -o y.o y.s
y.s: Assembler messages:
y.s:1: Warning: instruction length of 16 bytes exceeds the limit of 15
[hjl@gnu-cfl-3 pr31323]$ ./objdump -dw y.o

y.o:     file format elf64-x86-64


Disassembly of section .text:

0000000000000000 <.text>:
   0:   67 62 f4 ec 18 81 b4 10 00 00 00 00 e0 00 00    (bad)
        ...
