* Fix the bug that was preventing the parser from working on all bytecodeReid Spencer2004-06-081-5/+5

* Commit For New Tool: llvm-abcd (Analysis of ByteCode Dumper). This toolReid Spencer2004-06-076-0/+1881
| | | | | | | | | | | | | | | | | | | | | will (eventually) provide statistical analysis of bytecode files as well as the ability to dump them in a low level format (slot numbers not resolved). The purpose of this is to aid in the Type!=Value change of bug 122. With this initial release, llvm-abcd merely dumps out the bytecode. However, the infrastructure for separating bytecode parsing from handling the parsing events is in place. The style chosen is similar to SAX XML parsing where a handler object is called to handlign the parsing events. This probably isn't useful to anyone but me right now as there is no analysis yet, and the dumper doesn't work on every bytecode file. It will probably be useful by the end of this week. Note that there is some duplication of code from the bytecode reader. This was done to eliminate errors from being introduced in the reader and to minimize the impact to other LLVM developers. At some point, the Analyzer and the Reader will be integrated to use the same infrastructure. Also, sorry for the minor change to Instruction.h but I just couldn't bring myself to write code that depends on Instruction internals. llvm-svn: 14048

* 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. llvm-svn: 10914

* 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. llvm-svn: 10565

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. llvm-svn: 10392
* 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. llvm-svn: 10280

This dramatically reduces the number of allocations/deallocations performed by the bytecode reader, and speeds up parsing of Kimwitu++ from 34s to 17s. This is to help address PR127 llvm-svn: 10085
