2004-01-14When emitting bytecode, handle strings specially. Do not add the charactersChris Lattner
that make up the strings to the slotcalculator. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10862 91177308-0d34-0410-b5e6-96231b3b80d8
2004-01-14It is obvious that this has never been used for outputing more than a singleChris Lattner
byte, it's totally endian incorrect! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10857 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
2004-01-14Toggle sense of flagChris Lattner

2004-01-14The only clients of the slot calculator are now the asmwriter and bcwriter.Chris Lattner
Since this really only makes sense for these two, change hte instance variable to reflect whether we are writing a bytecode file or not. This makes it reasonable to add bcwriter specific stuff to it as necessary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10837 91177308-0d34-0410-b5e6-96231b3b80d8

2004-01-11Fix a regression that I introduced yesterday. :(Chris Lattner

2004-01-10Check in two changes:Chris Lattner
The first change (which is disabled) compactifies all of the function constant pools into the global constant pool, in an attempt to reduce the amount of duplication and overhead. Unfortunately, as the comment indicates, this is not yet a win, so it is disabled. The second change sorts the typeid's so that those types that can be used by instructions in the program appear earlier in the table than those that cannot (such as structures and arrays). This causes the instructions to be able to use the dense encoding more often, saving about 5K on 254.gap. This is only a .65% savings though, unfortunately. :( git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10754 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

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
