outweight its computational costs. This patch removes all compaction table handling from the bcreader and bcwriter. For the record, here's the difference betweeen having and not having compaction tables for some tests: Test With Without Size Chg Olden/mst 5,602 5,598 +0.1% viterbi 18,026 17,795 +1.3% obsequi 162,133 166,663 -2.8% burg 224,090 228,148 -1.8% kimwitu++ 4,933,263 5,121,159 -3.8% 176.gcc 8,470,424 9,141,539 -7.3% It seems that it is more beneficial to larger files, but even on the largest test case we have (176.gcc) it only amounts ot an I/O saving of 7.3%. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33661 91177308-0d34-0410-b5e6-96231b3b80d8
