--- Comment #1 from Luis Machado <lgustavo at codesourcery dot com> ---
I hit a different unsupported instruction with this testcase.
0x7ffff7dee6e7 <_dl_runtime_resolve_avx+71>: vmovdqa %ymm0,(%rsp)
The current mechanism for supporting these instructions is really inefficient.
Everytime we find a new unsupported instruction we need to hardcode the
knowledge inside gdb.
