* Use the true, decoded name of the archive member in getObjectType.Brian Gaeke2004-03-311-7/+10
| | | | | | | In ReadArchiveBuffer, make sure that MemberName is set in the case where getObjectType would want to return SVR4LongFilename. llvm-svn: 12567

* Save another 30K from 176.gcc by encoding the compaction table a bit moreChris Lattner2004-01-181-4/+17
| | | | | | intelligently. llvm-svn: 10918
* 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
* Bytecode format for LLVM 1.2 no longer explicitly encodes zeros in primitiveChris Lattner2004-01-172-10/+22
| | | | | | | type planes. This saves about 5k on 176.gcc, and is needed for a subsequent patch of mine I'm working on. llvm-svn: 10908
* Allow bytecode files to refer directly to global values as constants, insteadChris Lattner2004-01-151-2/+6
| | | | | | | | of forcing them to go through ConstantPointerRef's. This allows bytecode files to mirror .ll files, allows more efficient encoding, and makes it easier to eventually eliminate CPR's. llvm-svn: 10883

* Change all of the bytecode reader primitives to throw exceptions instead ofChris Lattner2004-01-155-244/+131
| | | | | | | | | | returning error codes. Because they don't return an error code, they can return the value read, which simplifies the code and makes the reader more efficient (yaay!). Also eliminate the special case code for little endian machines. llvm-svn: 10871

* 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
* Make getObjectType() smarter about ranlibbed Mac OS X archives.Brian Gaeke2003-12-171-0/+2

* Throw better error messages, by calling strerror(errno) when weBrian Gaeke2003-12-121-4/+9

* In getObjectType(), doxygenify comment, and take a pointer to theBrian Gaeke2003-12-111-50/+43
| | | | | | | | | | | | | beginning of the archive member data as an argument. Get rid of ParseLongFilenameSection(), which is dead. 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
* * Finegrainify namespacificationChris Lattner2003-11-192-73/+47
| | | | | | | | | | | | | * Strength reduce several data structures which were left over from the "bad old days" * Minor efficiency improvements * Major efficiency improvement: In BytecodeParser::insertValue, do not allocate a new ValueTab entry just because some value exists with a large type. 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
