2004-09-01Changes For Bug 352Reid Spencer
Move include/Config and include/Support into include/llvm/Config, include/llvm/ADT and include/llvm/Support. From here on out, all LLVM public header files must be under include/llvm/. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16137 91177308-0d34-0410-b5e6-96231b3b80d8
2004-08-17Bytecode File Format Changes:Reid Spencer
- File format version number bumped to 4 - Writer will now align nothing - Reader now only expects alignment for version 3 or earlier git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15875 91177308-0d34-0410-b5e6-96231b3b80d8
2004-07-25bug 263:Reid Spencer
- encode/decode target triple and dependent libraries bug 401: - fix encoding/decoding of FP values to be little-endian only bug 402: - initial (compatible) cut at 24-bit types instead of 32-bit - reduce size of block headers by 50% Other: - cleanup Writer by consolidating to one compilation unit, rem. other files - use a std::vector instead of std::deque so the buffer can be allocated in multiples of 64KByte chunks rather than in multiples of some smaller (default) number. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15210 91177308-0d34-0410-b5e6-96231b3b80d8
2004-07-04Add new methods outputTypes and outputCompactionTypes for handling TypesReid Spencer
separately from Values. This needed for bug 122. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14609 91177308-0d34-0410-b5e6-96231b3b80d8

2004-01-18Add support for writing bytecode files with compactiontables for bytecode files.Chris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10915 91177308-0d34-0410-b5e6-96231b3b80d8
2004-01-15If these blocks are empty, there is no reason to even emit the bytecode blocks.Chris Lattner
This saves about 15K in 176.gcc, coupled with another patch that I'm working on. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10889 91177308-0d34-0410-b5e6-96231b3b80d8
2004-01-14The new bytecode format supports emitting strings a special case. This isChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10864 91177308-0d34-0410-b5e6-96231b3b80d8
2004-01-10Refactor writer stuff out of include/llvm/Bytecode/Primitives.h. This isChris Lattner
internal implementation details for the writer, not public interfaces! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10738 91177308-0d34-0410-b5e6-96231b3b80d8
2003-12-01Emit & read more compressed bytecode by not emitting a bytecodeblock forChris Lattner
each basic block in function. Instead, just emit a stream of instructions, chopping up basic blocks based on when we find terminator instructions. This saves a fairly substantial chunk of bytecode space. In stripped, sample cases, for example, we get this reduction in size: 197.parser: 163036 -> 137180: 18.8% reduction 254.gap : 844936 -> 689392: 22.6% 255.vortex: 621724 -> 528444: 17.7% ... Not bad for something this simple. :) Note that this doesn't require a new bytecode version number at all, though version 1.1 should not need to support the old format. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10280 91177308-0d34-0410-b5e6-96231b3b80d8

2003-03-19Changes to the V2 bytecode format:Chris Lattner
- Null values are implicitly encoded instead of explicitly, this makes things more compact! - More compactly represent ConstantPointerRefs - Bytecode files are represented as: Header|GlobalTypes|GlobalVars/Function Protos|Constants|Functions|SymTab instead of Header|GlobalTypes|Constants|GlobalVars/Function Protos|Functions|SymTab which makes a lot of things simpler. Writer changes: - We now explictly encode versioning information in the bytecode files. - This allows new code to read bytecode files produced by old code, but new bytecode files can have enhancements such as the above. Although this makes the reader a bit more complex (having to deal with old formats), the writer only needs to be able to produce the most recent version. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@5749 91177308-0d34-0410-b5e6-96231b3b80d8
