The LEON5 can often dual issue instructions from the same 64-bit aligned
double word if there are no data dependencies. Add scheduling information
to avoid scheduling unpairable instructions back-to-back.
gcc/ChangeLog:

* config/sparc/sparc.c (struct processor_costs): Add LEON5 costs

on ALU instruction and FPU anti-dependencies.

OK for whatever branches you deem relevant, modulo a couple of nits:
+;; Avoid scheduling load/store, FPU, and multiplication instructions back
and multiply instructions
+;; Schedule three instructions between load and dependant instruction.
dependent
