Performance numbers before/after on MIPS-74kc @ 1GHz:
lowlevel-blt-bench results
Referent (before):
over_reverse_n_8888 = L1: 15.25 L2: 17.41 M: 13.53 ( 35.98%) HT: 6.43 VT: 5.98 R: 5.94 RT: 2.18 ( 22Kops/s)
in_n_8_8 = L1: 52.14 L2: 28.49 M: 58.28 (116.33%) HT: 36.30 VT: 35.57 R: 30.52 RT: 12.18 ( 50Kops/s)
Optimized:
over_reverse_n_8888 = L1: 60.07 L2: 47.72 M: 28.58 ( 76.01%) HT: 23.68 VT: 22.88 R: 22.04 RT: 12.62 ( 60Kops/s)
in_n_8_8 = L1: 89.10 L2: 84.76 M: 65.39 ( 43.44%) HT: 44.84 VT: 41.62 R: 40.66 RT: 17.65 ( 66Kops/s)
