--- Comment #6 from Rhys Kidd <rhyskidd@gmail.com> ---
pmovzxbd is an SSE4.1 instruction.
SSE4 isn't supported in 32 bit mode, only 64 bit mode. 32 bit mode supports
only up to and including SSSE3.
http://www.valgrind.org/docs/manual/manual-core.html#manual-core.limits
There are no current plans to support SSE4 on 32-bit. Please use 64-bit.
