@kellabyte@FransBouma does you know why the cache probing function isn't something less trivial? Seems like it should be possible…
@loganb @kellabyte @FransBouma Cache lookups are often on the critical path; extra complexity may reduce clock speed or add a pipe stage.

@danluu@kellabyte@FransBouma I guess, I'm just surprised there's not enough wiggle room to stuff in a XOR'ing w/the higher bits… -
@loganb@kellabyte@FransBouma My guess is that the effect is negligible for 8-way. See badly reproduced diagram http://web.cs.dal.ca/~mheywood/CSCI3121/Memory/02-MissRateReduction.pdf … - 1 more reply
