| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This shrinks the type_block of kc++ from 139901 bits to 99389 bits (0.55% to 0.39% of the file), a 40% reduction.

| | | | | | | | | | | | | | | | | | | | | with 6 bits where possible. This shrinks kc++ from 3324164B to 3183584B.

* Implement support for globally associating abbrevs with block IDs, whichChris Lattner2007-05-055-64/+264
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | relieves us from having to emit the abbrevs into each instance of the block. This shrinks kc.bit from 3368K to 3333K, but will be a more significant win once instructions are abbreviated.

| | | | | | | | | | | | | | | | | | 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? :) llvm-svn: 36759

* Add an "implies" field to features. This indicates that, if the currentBill Wendling2007-05-045-66/+132
