# Encodings for Neon data processing instructions where the T32 encoding
# is a simple transformation of the A32 encoding.
# More specifically, this file covers instructions where the A32 encoding is
# 0b1111_001p_qqqq_qqqq_qqqq_qqqq_qqqq_qqqq
# and the T32 encoding is
# 0b111p_1111_qqqq_qqqq_qqqq_qqqq_qqqq_qqqq
# This file works on the A32 encoding only; calling code for T32 has to
# transform the insn into the A32 version first.
