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
2004-01-17Bytecode format for LLVM 1.2 no longer explicitly encodes zeros in primitiveChris Lattner
type planes. This saves about 5k on 176.gcc, and is needed for a subsequent patch of mine I'm working on. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10908 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
2004-01-15Fix PR73: bytecode format inconsistentChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10876 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
2004-01-14Ok, I can't handle it. This is a temporary checkin of a ton of statistics thatChris Lattner
i'm using in my work to reduce the bytecode file sizes. These will eventually be removed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10849 91177308-0d34-0410-b5e6-96231b3b80d8

2004-01-10Do not bother to emit a BytecodeBlock for an empty symbol table. This commonlyChris Lattner
occurs when the symbol table for a module has been stripped, making all of the function local symbols go away. This saves 6728 bytes in the stripped bytecode file of 254.gap (which obviously has 841 functions), which isn't a ton, but helps and was easy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10750 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

more efficient encoding of varargs calls, and the new varargs intrinsics. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9221 91177308-0d34-0410-b5e6-96231b3b80d8

2003-10-16Add support for 'weak' linkage.Chris Lattner
For now, we translate linkonce into weak linkage in the bytecode format because we don't have enough bits to represent it. We will rev the bytecode version soon anyways, so this will be fixed in the near future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9170 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
