* Add support for reading bytecode files with compactiontables for bytecode files.Chris Lattner2004-01-183-41/+186
| | | | | | | | | 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@10914 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix PR#193.John Criswell2003-12-201-3/+12
| | | | | | | | | | | Modified ReadArchiveBuffer() so that it dynamically allocates the std::string object used to hold the bytecode object file's name. This is necessary because it is passed by reference to the new Module that is allocated to represent the bytecode object, and previously we were using a std::string that disappeared on function exit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10565 91177308-0d34-0410-b5e6-96231b3b80d8

In ReadArchiveBuffer(), implement support for 4.4BSD/MacOSX long filenames. This is kind of invasive, because they prepend the long filename to the archive member data, and then lie about the size. So we have to keep track of the real size. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10392 91177308-0d34-0410-b5e6-96231b3b80d8
* Emit & read more compressed bytecode by not emitting a bytecodeblock forChris Lattner2003-12-012-2/+44
| | | | | | | | | | | | | | | | | | | | 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
