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

2003-09-23Suggestions 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

2003-08-24Allow modules to have 'any' pointer size and endianness. Luckily, we hadChris Lattner
some space for extra flags, so we don't need to bump the revision number. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8118 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

2002-11-20 - Eliminated the deferred symbol table stuff in Module & Function, it reallyChris Lattner
wasn't an optimization and it was causing lots of bugs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4779 91177308-0d34-0410-b5e6-96231b3b80d8
2002-10-23 - Fix a really nasty bug in the bytecode reader that caused it to failChris Lattner
reading bytecode files with > 255 types in them, but only when optimization is enabled. This was caused by GCC shrinking an enum to a single byte instead of a whole word. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4266 91177308-0d34-0410-b5e6-96231b3b80d8

2002-10-14There is no way to guarantee that constants are not forward referenced.Chris Lattner
Handle forward referenced constants in a general way. This fixes bug: Assembler/2002-10-13-ConstantEncodingProblem.llx and allows the SPEC 197.parser benchmark to be built git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4161 91177308-0d34-0410-b5e6-96231b3b80d8

2002-08-17 - Finally nailed: test/Regression/Assembler/2002-08-16-ConstExprInlined.llxChris Lattner
- ParseConstantPool was resolving reference to value using the function slot # instead of the global slot #. - Bytecode reader changes: - Remove the failure<> template from Bytecode Reader - Remove extraneous #includes - s/method/function/ a bit - Eliminate the fwdRefs class that just added abstraction where it was not needed, making things more complex. - Use a vector instead of a list for function signatures. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@3366 91177308-0d34-0410-b5e6-96231b3b80d8
