# TODO(mark): Unicorn 1.0.1 does not support reading YMM registers,
# and simply returns back zero. If a unicorn emulated instruction writes to an
# XMM reg, we will read back the corresponding YMM register, resulting in an
# incorrect zero value being actually written to the XMM register. This is
# fixed in Unicorn PR #819, so when that is included in a release, delete
# these two lines.

# XXX(yan): This concretizes the entire register state. This is overly
