This is really a question for the assembler, not for gcc. The
assembler is not part of gcc. It is part of the GNU binutils. See
http://sourceware.org/binutils/ .
The wunpckelub instruction only exists on processors which support the
iwmmxt instructions. You can indicate that your processor supports
those extensions by doing something like -Wa,-march=armv5te+iwmmxt.
See the assembler manual. Needless to say, this will only work if
your processor does in fact support iwmmxt.
