* Rename Type::PrimitiveID to TypeId and ::getPrimitiveID() to ::getTypeID()Chris Lattner2004-06-171-2/+2
| | | | llvm-svn: 14201
* Implement support for a new LLVM 1.3 bytecode format, which uses uint'sChris Lattner2004-04-051-3/+8
| | | | | | | to index into structure types and allows arbitrary 32- and 64-bit integer types to index into sequential types. llvm-svn: 12651
* Remove a bunch of cruft that was used to be backwards compatible with the lastChris Lattner2004-04-031-26/+5
| | | | | | | prerelease format for LLVM bytecode files. Now we only are compatible with LLVM 1.0+. llvm-svn: 12643
* Make error message a bit nicer.Chris Lattner2004-03-291-1/+1

* 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 Lattner2004-01-181-30/+129
| | | | | | | | 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 Lattner2004-01-171-8/+14
| | | | | | | 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
* Fix PR73Chris Lattner2004-01-151-1/+10
| | | | llvm-svn: 10875
* Change all of the bytecode reader primitives to throw exceptions instead ofChris Lattner2004-01-151-37/+18
| | | | | | | | | | 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
* Version 1.2 now supports encoding strings as a special case, to avoid havingChris Lattner2004-01-141-2/+5
| | | | | | to emit all of those sbyte constants. llvm-svn: 10863

* Emit & read more compressed bytecode by not emitting a bytecodeblock forChris Lattner2003-12-011-1/+41
| | | | | | | | | | | | | | | | | | | 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 Lattner2003-11-191-59/+34
| | | | | | | | | | | | | * 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
* Minor speedup to do less linear time searches of information we already have.Chris Lattner2003-11-191-2/+3
| | | | | | speeds up disassembly of kc++ by .6s llvm-svn: 10079
* Put all LLVM code into the llvm namespace, as per bug 109.Brian Gaeke2003-11-111-0/+4
| | | | llvm-svn: 9903
* Added LLVM project notice to the top of every C++ source file.John Criswell2003-10-201-0/+7
| | | | | | Header files will be on the way. llvm-svn: 9298
* Fix warningChris Lattner2003-10-181-0/+1

* add support for new linkage typesChris Lattner2003-10-181-4/+14
| | | | llvm-svn: 9228
* * New revised variable argument handling supportChris Lattner2003-10-181-33/+30
| | | | | | | * More dense bytecode encoding for varargs calls (like printf) * Eliminated the extremely old bytecode format. rev #0 is now 1.0 llvm-svn: 9220
* Add support for 'weak' linkage.Chris Lattner2003-10-161-2/+12
| | | | | | | | For now, we translate linkonce into weak linkage in the bytecode format because we don't have enough bits to represent it. We will rev the bytecode version soon anyways, so this will be fixed in the near future. llvm-svn: 9170
* Minor cleanupsChris Lattner2003-10-131-2/+2
| | | | llvm-svn: 9079
* Avoid calling getTypeSlot moreChris Lattner2003-10-131-3/+7
| | | | llvm-svn: 9077
* Ok, the "fix" for this is to do a real associative container. Symbol tablesChris Lattner2003-10-101-15/+11
| | | | | | | are ordered by name, not by slot, so the previous solution wasn't any good. On a large testcase, this reduces time to parse from 2.17s to 1.58s. llvm-svn: 9002
* Another 10% performance improvement by not using replaceAllUsesWithChris Lattner2003-10-091-13/+20
| | | | llvm-svn: 8994
* Use the version of getValue that takes the type plane instead of the typeChris Lattner2003-10-091-1/+2
| | | | | | if possible. This provides a consistent 8.5% speedup. llvm-svn: 8991
* Pass a vector around to reduce dynamic allocationChris Lattner2003-10-091-1/+2
| | | | | | Throw the RawInst class in an anon namespace llvm-svn: 8990
* Change getConstantValue to throw an exception on error, not return nullChris Lattner2003-10-091-1/+4
| | | | llvm-svn: 8988
* Remove potentially N^2 algorithm from symbol table reader. No speedupChris Lattner2003-10-091-5/+13
| | | | | | in practice though llvm-svn: 8985
* Major refactoring of the bytecode reader. This includes the followingChris Lattner2003-10-091-31/+18
| | | | | | | | | | | | | | | changes: * BytecodeReader::getType(...) used to return a null pointer on error. This was only checked about half the time. Now we convert it to throw an exception, and delete the half that checked for error. This was checked in before, but psmith crashed and lost the change :( * insertValue no longer returns -1 on error, so callers don't need to check for it. * Substantial rewrite of InstructionReader.cpp, to use more efficient, simpler, data structures. This provides another 5% speedup. This also makes the code much easier to read and understand. llvm-svn: 8984
* Significantly clean up parsing of instructions. This exceptionizes andChris Lattner2003-10-091-4/+1
| | | | | | | simplifies the control flow a bit. This provides a small (~3%) speedup, but it's primarily a cleanup exercise. llvm-svn: 8983
* Eliminate the instruction placeholder. Simplify a bunch of code.Chris Lattner2003-10-091-1/+1
| | | | | | This results in no significant speedup, but does provide simpler code llvm-svn: 8980
* Eliminate the old LateResolveValues data structure, replacing it with aChris Lattner2003-10-091-23/+25
| | | | | | | | | | | | | new, simpler, ForwardReferences data structure. This is just the first simple replacement, subsequent changes will improve the code more. This simple change improves the performance of loading a file from HDF5 (contributed by Bill) from 2.36s to 1.93s, a 22% improvement. This presumably has to do with the fact that we only create ONE placeholder for a particular forward referenced values, and also may be because the data structure is much simpler. llvm-svn: 8979
* Remove a dead methodChris Lattner2003-10-091-11/+0
| | | | llvm-svn: 8978
* This patch substantially simplifies and cleans up handling of basic blocksChris Lattner2003-10-081-22/+57
| | | | | | | | | | | | | in the bytecode parser. Before we tried to shoehorn basic blocks into the "getValue" code path with other types of values. For a variety of reasons this was a bad idea, so this patch separates it out into its own data structure. This simplifies the code, makes it fit in 80 columns, and is also much faster. In a testcase provided by Bill, which has lots of PHI nodes, this patch speeds up bytecode parsing from taking 6.9s to taking 2.32s. More speedups to follow later. llvm-svn: 8977
* Inline the postResolveValues method. It was poorly named anywayChris Lattner2003-10-081-29/+24
| | | | llvm-svn: 8976
* Various cleanups and simplifications. This speeds up reading a bytecode fileChris Lattner2003-10-081-43/+38
| | | | | | Bill gave me from 8.69s to 6.90s. llvm-svn: 8971
* Transform two methods to return pointers directly instead of returning themChris Lattner2003-10-041-26/+18
| | | | | | as 'by reference' arguments. llvm-svn: 8849
* Use V for values, not D.Chris Lattner2003-10-041-16/+15
| | | | llvm-svn: 8848
* Just rethrow previous exception instead of making a new oneChris Lattner2003-09-261-1/+1
| | | | llvm-svn: 8718
* Suggestions made by Chris:Misha Brukman2003-09-231-10/+14
| | | | | | | | | * Instead of a #define, use inline function * Fix the name on the #define, errr... now inline function to be more logical: it doesn't CHECK the alignment, it PERFORMS the alignment * To get string name of a Type*, use getDescription(), not getName() llvm-svn: 8683
* * Cleaned up code:Misha Brukman2003-09-221-262/+161
| | | | | | | | | - no more passing around a string pointer to set errors - no more returning booleans and checking for errors, we use C++ exceptions * Broke functionality into 2 new classes, one reads from file, one from a stream * Implemented lazy function streaming - the parser can read in a function at-a-time llvm-svn: 8671
* Fixed spelling and grammar.Misha Brukman2003-09-111-1/+1

* Allow modules to have 'any' pointer size and endianness. Luckily, we hadChris Lattner2003-08-241-11/+20
