[mips] interAptiv based generic schedule model

[sdardis]

Summary

This scheduler describes a processor which covers all MIPS ISAs based
around the interAptiv and P5600 timings.

[dsanders]

LGTM with the ResourceCycles corrected, a couple other minor changes, and an explanation for the dsr-fixed-objects.ll change

lib/Target/Mips/Mips.td

If MipsGenericItineraries is no longer used can we delete it (in a follow-up patch)?

lib/Target/Mips/MipsScheduleGeneric.td

203–204

Could you uncomment these and add II_MFHC0 to the microMIPSR6 definitions? We don't seem to have MFHC0 for the other ISA's it exists for.

350–381

I doubt these are working as intended since there are two ResourceCycles elements but only one resource and ResourceCycles are paired up with the resources. I think the current definition for GenericWriteFPUSqrtD is saying that it consumes the GenericFPUDivSqrt resource for a single cycle which is equivalent to a fully-pipelined divide path.

I think you need to remove each of the '1' elements since these corresponded with an issue port on the P5600 definitions.

Likewise for GenericDiv other places where ResourceCycles is set.

Could you explain why this changed?

This change occurred as an instruction moved before a label.

Ok, thanks.

This might just need a clean build, looking into that now.

I included that missing file in rL280377 . Sorry about the breakage.

That seems to have fixed it, thanks!
