* The ModuleLevel vector is often quite sparse. Switch it to a DenseMap. ThisChris Lattner2007-02-102-18/+24
| | | | | | speeds up bcwriting of 447.dealII by 40%, from 4.63s to 3.32s. llvm-svn: 34135
* Make the ModuleLevel datastructure more sane. When a function-local valueChris Lattner2007-02-102-33/+19
| | | | | | | | is inserted into the table, it remembers that the value needs to be popped off. This makes purgeFunction much faster, speeding up bcwriting of 447.dealII from 6.8->4.6s (47%). llvm-svn: 34133
* Only compute the module levels info once per module, instead of onceChris Lattner2007-02-101-15/+7

* 1. constants can never occur in the symbol table.Chris Lattner2007-02-093-21/+0
| | | | | | | | | | | 2. All function-level constants are now incorporated into the module-level constant pool, since the compaction table was removed. Eliminate extra work to check for them. This speeds up the bcwriter from 24.4s to 13.1s on 447.dealII and .73 -> .56s on kc++ in a release build. llvm-svn: 34084

* For PR411:Reid Spencer2007-02-057-61/+73
| | | | | | | | | | This patch replaces the SymbolTable class with ValueSymbolTable which does not support types planes. This means that all symbol names in LLVM must now be unique. The patch addresses the necessary changes to deal with this and removes code no longer needed as a result. This completes the bulk of the changes for this PR. Some cleanup patches will follow. llvm-svn: 33918
* Changes to support making the shift instructions be true BinaryOperators.Reid Spencer2007-02-021-7/+0
| | | | | | | | | | | | This feature is needed in order to support shifts of more than 255 bits on large integer types. This changes the syntax for llvm assembly to make shl, ashr and lshr instructions look like a binary operator: shl i32 %X, 1 instead of shl i32 %X, i8 1 Additionally, this should help a few passes perform additional optimizations. llvm-svn: 33776

* Bye, Bye Compaction Tables. The benefit compaction tables provides doesn'tReid Spencer2007-01-306-722/+35
| | | | | | | | | | | | | | | | | | | 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%. llvm-svn: 33661
