* 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9170 91177308-0d34-0410-b5e6-96231b3b80d8

* 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9002 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | tasty 15% speedup on the testcase from Bill. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8993 91177308-0d34-0410-b5e6-96231b3b80d8
* Use the version of getValue that takes the type plane instead of the typeChris Lattner2003-10-092-17/+18
| | | | | | | 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

* Major refactoring of the bytecode reader. This includes the followingChris Lattner2003-10-094-315/+171
| | | | | | | | | | | | | | | | 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
* Significantly clean up parsing of instructions. This exceptionizes andChris Lattner2003-10-093-144/+106
| | | | | | | | 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
* Eliminate the instruction placeholder. Simplify a bunch of code.Chris Lattner2003-10-092-15/+1
| | | | | | | 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
* Eliminate the old LateResolveValues data structure, replacing it with aChris Lattner2003-10-092-25/+27
| | | | | | | | | | | | | | 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
* Remove a dead methodChris Lattner2003-10-092-12/+0
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8978 91177308-0d34-0410-b5e6-96231b3b80d8
* This patch substantially simplifies and cleans up handling of basic blocksChris Lattner2003-10-083-60/+84
| | | | | | | | | | | | | | 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
* Inline the postResolveValues method. It was poorly named anywayChris Lattner2003-10-082-34/+26

* Various cleanups and simplifications. This speeds up reading a bytecode fileChris Lattner2003-10-083-61/+57
| | | | | | | 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

* Rename AbstractModuleProvider -> ModuleProvider, to match the header file name,Chris Lattner2003-10-042-7/+5
