2016-04-18[NFC] Header cleanupMehdi Amini1-1/+0
Removed some unused headers, replaced some headers with forward class declarations. Found using simple scripts like this one: clear && ack --cpp -l '#include "llvm/ADT/IndexedMap.h"' | xargs grep -L 'IndexedMap[<]' | xargs grep -n --color=auto 'IndexedMap' Patch by Eugene Kosov <claprix@yandex.ru> Differential Revision: http://reviews.llvm.org/D19219 From: Mehdi Amini <mehdi.amini@apple.com> llvm-svn: 266595

2013-09-09Revert patches to add case-range support for PR1255.Bob Wilson1-4/+4
The work on this project was left in an unfinished and inconsistent state. Hopefully someone will eventually get a chance to implement this feature, but in the meantime, it is better to put things back the way the were. I have left support in the bitcode reader to handle the case-range bitcode format, so that we do not lose bitcode compatibility with the llvm 3.3 release. This reverts the following commits: 155464, 156374, 156377, 156613, 156704, 156757, 156804 156808, 156985, 157046, 157112, 157183, 157315, 157384, 157575, 157576, 157586, 157612, 157810, 157814, 157815, 157880, 157881, 157882, 157884, 157887, 157901, 158979, 157987, 157989, 158986, 158997, 159076, 159101, 159100, 159200, 159201, 159207, 159527, 159532, 159540, 159583, 159618, 159658, 159659, 159660, 159661, 159703, 159704, 160076, 167356, 172025, 186736 llvm-svn: 190328
2013-01-02Move all of the header files which are involved in modelling the LLVM IRChandler Carruth1-4/+4
into their new header subdirectory: include/llvm/IR. This matches the directory structure of lib, and begins to correct a long standing point of file layout clutter in LLVM. There are still more header files to move here, but I wanted to handle them in separate commits to make tracking what files make sense at each layer easier. The only really questionable files here are the target intrinsic tablegen files. But that's a battle I'd rather not fight today. I've updated both CMake and Makefile build systems (I think, and my tests think, but I may have missed something). I've also re-sorted the includes throughout the project. I'll be committing updates to Clang, DragonEgg, and Polly momentarily. llvm-svn: 171366
2012-12-04Sort the #include lines for tools/...Chandler Carruth1-7/+5
Again, tools are trickier to pick the main module header for than library source files. I've started to follow the pattern of using LLVMContext.h when it is included as a stub for program source files. llvm-svn: 169252

2012-03-08Taken into account Duncan's comments for r149481 dated by 2nd Feb 2012:Stepan Dyatkovskiy1-5/+9
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. llvm-svn: 152297
2012-02-01SwitchInst refactoring.Stepan Dyatkovskiy1-4/+4
The purpose of refactoring is to hide operand roles from SwitchInst user (programmer). If you want to play with operands directly, probably you will need lower level methods than SwitchInst ones (TerminatorInst or may be User). After this patch we can reorganize SwitchInst operands and successors as we want. What was done: 1. Changed semantics of index inside the getCaseValue method: getCaseValue(0) means "get first case", not a condition. Use getCondition() if you want to resolve the condition. I propose don't mix SwitchInst case indexing with low level indexing (TI successors indexing, User's operands indexing), since it may be dangerous. 2. By the same reason findCaseValue(ConstantInt*) returns actual number of case value. 0 means first case, not default. If there is no case with given value, ErrorIndex will returned. 3. Added getCaseSuccessor method. I propose to avoid usage of TerminatorInst::getSuccessor if you want to resolve case successor BB. Use getCaseSuccessor instead, since internal SwitchInst organization of operands/successors is hidden and may be changed in any moment. 4. Added resolveSuccessorIndex and resolveCaseIndex. The main purpose of these methods is to see how case successors are really mapped in TerminatorInst. 4.1 "resolveSuccessorIndex" was created if you need to level down from SwitchInst to TerminatorInst. It returns TerminatorInst's successor index for given case successor. 4.2 "resolveCaseIndex" converts low level successors index to case index that curresponds to the given successor. Note: There are also related compatability fix patches for dragonegg, klee, llvm-gcc-4.0, llvm-gcc-4.2, safecode, clang. llvm-svn: 149481

2010-08-24Check in a couple of changes that I apparently never committed:John McCall1-0/+33
- teach DifferenceEngine to unify successors of calls and invokes in certain circumstances - basic blocks actually don't have their own numbering; did that change? - add llvm-diff to the Makefile and CMake build systems llvm-svn: 111909

2010-07-29When unifying instructions during a block diff, actually complain aboutJohn McCall1-1/+1
any differences we see. This should only happen if there are "non-structural" differences between the instructions, i.e. differences which wouldn't cause diff to return true. llvm-svn: 109742

in despite not ever incrementing any path costs, so that the only nonzero costs arose from the all-left path in the first column. Anyway. Perform the diff starting from the beginning of the block to avoid capturing (say) loads of allocas. Vastly improves diff results on code that hasn't been mem2reg'ed. llvm-svn: 109741
