[PATCH 02/33] target/mips: Fix MSA MADDV.B opcode |
Date: |

The result of the 'Vector Multiply and Add' opcode is incorrect
with Byte vectors. Probably due to a copy/paste error, commit
7a7a162adde mistakenly used the $wt (target register) instead
of $wd (destination register) as first operand. Fix that.
