I had done that on alpha, but didn't initially report the figures.  Would
a comparison to 2.95 also be useful?

gcc version 3.3 20020802 (experimental)

---------------------------------------------------------------------------
cc1 -O2 reload.i

issues/cycles = 0.51  issues/dcache_miss = 26.93  issues/dtb_miss = 1214.36

---------------------------------------------------------------------------
cc1 reload.i

issues/cycles = 0.52  issues/dcache_miss = 31.29  issues/dtb_miss = 1854.16
