* Part of bug 122:Reid Spencer2004-05-261-1/+1
| | | | | | | | | | This change removes the BuildBytecodeInfo flag from the SlotCalculator class. This flag was needed to distinguish between the Bytecode/Writer and the AsmWriter. Now that AsmWriter doesn't use SlotCalculator, we can remove this flag and simplify some code. Also, some minor name changes to CachedWriter.h needed to be committed (missed in previous commit). llvm-svn: 13785

| | | | | | | | | | | | | the Abstract Data Type that holds slot number values and associates them with Type* and Value*. The SlotTable is simply the holder of the slot numbers and provides a controlled interface for building the table. It does not enforce any particular idiom or functionality for manipulating the slot numbers. This is part of bug_122. The SlotCalculator and SlotMachine classes will follow. llvm-svn: 13764

| | | | | | | | This shrinks the bytecode file for 176.gcc by about 200K (10%), and 254.gap by about 167K, a 25% reduction. There is still a lot of room for improvement in the encoding of the compaction table. llvm-svn: 10915

* The new bytecode format supports emitting strings a special case. This isChris Lattner2004-01-143-21/+63
| | | | | | | | | | | | intended to save size (and does on small programs), but on big programs it actually increases the size of the program slightly. The deal is that many functions end up using the characters that the string contained, and the characters are no longer in the global constant table, so they have to be emitted in function specific constant pools. This pessimization will be fixed in subsequent patches. llvm-svn: 10864
