* [llvm.py] Initial skeleton for Python LLVM bindingsGregory Szorc2012-03-097-0/+361
| | | | | | | | | | | | | | | This contains a semi-functional skeleton for the implementation of the LLVM bindings for Python. The API for the Object.h interface is roughly designed but not implemented. MemoryBufferRef is implemented and actually appears to work! The ObjectFile unit test fails with a segmentation fault because the LLVM library isn't being properly initialized. The build system doesn't know about this code yet, so no alerts should fire. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152397 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | caused several clients to select the slow variation. =[ This is extra annoying because we don't have any realistic way of testing this -- by design, these two functions *must* compute the same value. Found while inspecting the output of some benchmarks I'm working on. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152369 91177308-0d34-0410-b5e6-96231b3b80d8
* Undo a previous restriction on the inline cost calculation which NickChandler Carruth2012-03-092-107/+187
| | | | | | | | | | | | | | | | | | | | | | introduced. Specifically, there are cost reductions for all constant-operand icmp instructions against an alloca, regardless of whether the alloca will in fact be elligible for SROA. That means we don't want to abort the icmp reduction computation when we abort the SROA reduction computation. That in turn frees us from the need to keep a separate worklist and defer the ICmp calculations. Use this new-found freedom and some judicious function boundaries to factor the innards of computing the cost factor of any given instruction out of the loop over the instructions and into static helper functions. This greatly simplifies the code, and hopefully makes it more clear what is happening here. Reviewed by Eric Christopher. There is some concern that we'd like to ensure this doesn't get out of hand, and I plan to benchmark the effects of this change over the next few days along with some further fixes to the inline cost. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152368 91177308-0d34-0410-b5e6-96231b3b80d8

* Taken into account Duncan's comments for r149481 dated by 2nd Feb 2012:Stepan Dyatkovskiy2012-03-0825-211/+302
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20120130/136146.html Implemented CaseIterator and it solves almost all described issues: we don't need to mix operand/case/successor indexing anymore. Base iterator class is implemented as a template since it may be initialized either from "const SwitchInst*" or from "SwitchInst*". ConstCaseIt is just a read-only iterator. CaseIt is read-write iterator; it allows to change case successor and case value. Usage of iterator allows totally remove resolveXXXX methods. All indexing convertions done automatically inside the iterator's getters. Main way of iterator usage looks like this: SwitchInst *SI = ... // intialize it somehow for (SwitchInst::CaseIt i = SI->caseBegin(), e = SI->caseEnd(); i != e; ++i) { BasicBlock *BB = i.getCaseSuccessor(); ConstantInt *V = i.getCaseValue(); // Do something. } If you want to convert case number to TerminatorInst successor index, just use getSuccessorIndex iterator's method. If you want initialize iterator from TerminatorInst successor index, use CaseIt::fromSuccessorIndex(...) method. There are also related changes in llvm-clients: klee and clang. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152297 91177308-0d34-0410-b5e6-96231b3b80d8
