2004-06-29Remove files no longer needed. ConstantReader and InstructionReader wereReid Spencer
integrated into Reader. Parser.* was just a bad idea. AnalyzerInternals.h is no longer needed. ReaderPrimitives.h was integrated into Reader.h and Reader.cpp. Dumper.cpp was integrated into Analyzer.cpp. ReaderInternals.h became Reader.h. AnalyzerWrappers.cpp was integerated into ReaderWrappers.cpp git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14496 91177308-0d34-0410-b5e6-96231b3b80d8

2004-04-05Implement support for a new LLVM 1.3 bytecode format, which uses uint'sChris Lattner
to index into structure types and allows arbitrary 32- and 64-bit integer types to index into sequential types. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12651 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-03Remove a bunch of cruft that was used to be backwards compatible with the lastChris Lattner

2004-01-18Add support for reading bytecode files with compactiontables for bytecode files.Chris Lattner
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
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

2004-01-15Change all of the bytecode reader primitives to throw exceptions instead ofChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10871 91177308-0d34-0410-b5e6-96231b3b80d8

2003-12-01Emit & read more compressed bytecode by not emitting a bytecodeblock forChris Lattner
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
2003-11-19* Finegrainify namespacificationChris Lattner
* 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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10085 91177308-0d34-0410-b5e6-96231b3b80d8

2003-10-09Major refactoring of the bytecode reader. This includes the followingChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8984 91177308-0d34-0410-b5e6-96231b3b80d8
2003-10-09Significantly clean up parsing of instructions. This exceptionizes andChris Lattner
simplifies the control flow a bit. This provides a small (~3%) speedup, but it's primarily a cleanup exercise. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8983 91177308-0d34-0410-b5e6-96231b3b80d8
2003-10-09Eliminate the instruction placeholder. Simplify a bunch of code.Chris Lattner
This results in no significant speedup, but does provide simpler code git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8980 91177308-0d34-0410-b5e6-96231b3b80d8
2003-10-09Eliminate the old LateResolveValues data structure, replacing it with aChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8979 91177308-0d34-0410-b5e6-96231b3b80d8

2003-10-08This patch substantially simplifies and cleans up handling of basic blocksChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8977 91177308-0d34-0410-b5e6-96231b3b80d8

2003-03-19* Bug fixes:Chris Lattner
- Fix problems where the constant table would not get updated when resolving constants causes other constants to change. Changes to the V2 bytecode format - Null values are implicitly encoded instead of explicitly, this makes things more compact! - More compactly represent ConstantPointerRefs - Bytecode files are represented as: Header|GlobalTypes|GlobalVars/Function Protos|Constants|Functions|SymTab instead of Header|GlobalTypes|Constants|GlobalVars/Function Protos|Functions|SymTab which makes a lot of things simpler. Changes to the reader: - Function loading code is much simpler.
