LGTM with few small changes, the most important being the addition of the entries missing from the MipsGenericItineraries table.

lib/Target/Mips/Mips32r6InstrInfo.td

248

Can we move the InstrItinClass parameter at the of the parameter list, in order to have the instruction's operands next to each other? Similarly for the 2-3 cases below.

lib/Target/Mips/MipsSchedule.td

39

We don't have an entry for this in the MipsGenericItineraries table. Similarly for II_BCCC below.

test/CodeGen/Mips/divrem.ll

158

I think that we have to use -DAG here as the order of the div/mod instructions doesn't require a strict order. Similarly for the cases below.

test/CodeGen/Mips/llvm-ir/mul.ll

172–175

We should use the -DAG suffix for these. Also, can you rename the temporaries in order to have an increasing numbering. Similarly, for 64R6 below.

Addressed comments, can you commit on my behalf? Thanks.
