Subject: target/mips: Convert MSA I5 instruction format to decodetree
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Convert instructions with a 5-bit immediate value to decodetree.
Since the 'data format' field is a constant value, use
tcg_constant_i32() instead of a TCG temporary.
