2004-01-20Major changes. Now we only compactify individual type planes if it is inChris Lattner
fact "profitable" to do so. This makes compactification "free" for small programs (ie, it is completely disabled) and even helps large programs by not having to encode pointless compactification planes. On 176.gcc, this saves 50K from the bytecode file, which is, alas only a couple percent. This concludes my head bashing against the bytecode format, at least for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10922 91177308-0d34-0410-b5e6-96231b3b80d8
2004-01-18Add support for building the compactiontable for bytecode files. This shrinksChris Lattner
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@10913 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

2004-01-14When 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
2004-01-14The 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

2004-01-10Check 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
