2007-05-04allow the 8-bit abbrev to be used for either bb or other valuesChris Lattner

2007-05-04shave another 150K off of kc++, by using a 7-bit encoding for BB namesChris Lattner
where we can. This shrinks kc++'s down to 3368K, with a VST record of: Block ID #14 (VALUE_SYMTAB): Num Instances: 2345 Total Size: 1.29508e+07b/1.61885e+06B/404713W Average Size: 5522.73b/690.342B/172.585W % of file: 48.0645 Tot/Avg SubBlocks: 0/0 Tot/Avg Abbrevs: 7035/3 Tot/Avg Records: 120924/51.5667 % Abbrev Recs: 100 Isn't it nice to be able to optimizer bc size without touching the reader? :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@36759 91177308-0d34-0410-b5e6-96231b3b80d8
2007-05-04where possible, encode symtab names with 7 bits per char instead of 8. ThisChris Lattner

2007-05-04Encode all value symtab strings as arrays of 8-bit fixed width integers,Chris Lattner
instead of the default inefficient encoding. This shrinks kc++ from 4134K to 3629K git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@36755 91177308-0d34-0410-b5e6-96231b3b80d8
