* 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

* 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

* 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
