2003-10-18* New revised variable argument handling supportChris Lattner
* More dense bytecode encoding for varargs calls (like printf) * Eliminated the extremely old bytecode format. rev #0 is now 1.0 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9220 91177308-0d34-0410-b5e6-96231b3b80d8
2003-10-16Add support for 'weak' linkage.Chris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9170 91177308-0d34-0410-b5e6-96231b3b80d8

2003-10-13Avoid calling getTypeSlot moreChris Lattner

2003-10-10Ok, the "fix" for this is to do a real associative container. Symbol tablesChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9002 91177308-0d34-0410-b5e6-96231b3b80d8
2003-10-09Another 10% performance improvement by not using replaceAllUsesWithChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8994 91177308-0d34-0410-b5e6-96231b3b80d8
2003-10-09Use the version of getValue that takes the type plane instead of the typeChris Lattner
if possible. This provides a consistent 8.5% speedup. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8991 91177308-0d34-0410-b5e6-96231b3b80d8
2003-10-09Pass a vector around to reduce dynamic allocationChris Lattner
Throw the RawInst class in an anon namespace git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8990 91177308-0d34-0410-b5e6-96231b3b80d8
2003-10-09Change getConstantValue to throw an exception on error, not return nullChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8988 91177308-0d34-0410-b5e6-96231b3b80d8
2003-10-09Remove potentially N^2 algorithm from symbol table reader. No speedupChris Lattner
in practice though git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8985 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
2003-10-09Remove a dead methodChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8978 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
2003-10-08Inline the postResolveValues method. It was poorly named anywayChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8976 91177308-0d34-0410-b5e6-96231b3b80d8
2003-10-08Various cleanups and simplifications. This speeds up reading a bytecode fileChris Lattner
Bill gave me from 8.69s to 6.90s. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8971 91177308-0d34-0410-b5e6-96231b3b80d8
2003-10-04Transform two methods to return pointers directly instead of returning themChris Lattner
as 'by reference' arguments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8849 91177308-0d34-0410-b5e6-96231b3b80d8

2003-09-26Just rethrow previous exception instead of making a new oneChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8718 91177308-0d34-0410-b5e6-96231b3b80d8
2003-09-23Suggestions made by Chris:Misha Brukman
* 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() git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8683 91177308-0d34-0410-b5e6-96231b3b80d8
2003-09-22* Cleaned up code:Misha Brukman
- 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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8671 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. We now no longer make function PlaceHolderHelper objects to be replaced with real functions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@5748 91177308-0d34-0410-b5e6-96231b3b80d8
