2005-04-27Implement Value* tracking for loads and stores in the selection DAG. This ↵Andrew Lenharth
enables one to use alias analysis in the backends. (TRUNK)Stores and (EXT|ZEXT|SEXT)Loads have an extra SDOperand which is a SrcValueSDNode which contains the Value*. Note that if the operation is introduced by the backend, it will still have the operand, but the value* will be null. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21599 91177308-0d34-0410-b5e6-96231b3b80d8

2005-04-27This is a cleanup commit:Reid Spencer
* Correct stale documentation in a few places * Re-order the file to better associate things and reduce line count * Make the pass thread safe by caching the Function* objects needed by the optimizers in the pass object instead of globally. * Provide the SimplifyLibCalls pass object to the optimizer classes so they can access cached Function* objects and TargetData info * Make sure the pass resets its cache if the Module passed to runOnModule changes * Rename CallOptimizer LibCallOptimization. All the classes are named *Optimization while the objects are *Optimizer. * Don't cache Function* in the optimizer objects because they could be used by multiple PassManager's running in multiple threads * Add an optimization for strcpy which is similar to strcat * Add a "TODO" list at the end of the file for ideas on additional libcall optimizations that could be added (get ideas from other compilers). Sorry for the huge diff. Its mostly reorganization of code. That won't happen again as I believe the design and infrastructure for this pass is now done or close to it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21589 91177308-0d34-0410-b5e6-96231b3b80d8

2005-04-26Fix some bugs found by running on llvm-test:Reid Spencer
* MemCpyOptimization can only be optimized if the 3rd and 4th arguments are constants and we weren't checking for that. * The result of llvm.memcpy (and llvm.memmove) is void* not sbyte*, put in a cast. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21570 91177308-0d34-0410-b5e6-96231b3b80d8
2005-04-26Changes From Review Feedback:Reid Spencer
* Have the SimplifyLibCalls pass acquire the TargetData and pass it down to the optimization classes so they can use it to make better choices for the signatures of functions, etc. * Rearrange the code a little so the utility functions are closer to their usage and keep the core of the pass near the top of the files. * Adjust the StrLen pass to get/use the correct prototype depending on the TargetData::getIntPtrType() result. The result of strlen is size_t which could be either uint or ulong depending on the platform. * Clean up some coding nits (cast vs. dyn_cast, remove redundant items from a switch, etc.) * Implement the MemMoveOptimization as a twin of MemCpyOptimization (they only differ in name). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21569 91177308-0d34-0410-b5e6-96231b3b80d8
