| 2010-11-13 | Fix typo pointed out by Trevor Harmon. | Duncan Sands | 1 | -1/+1 | |
| llvm-svn: 119001 | |||||
| 2010-10-12 | Begin adding static dependence information to passes, which will allow us to | Owen Anderson | 1 | -1/+3 | |
| perform initialization without static constructors AND without explicit initialization by the client. For the moment, passes are required to initialize both their (potential) dependencies and any passes they preserve. I hope to be able to relax the latter requirement in the future. llvm-svn: 116334 | |||||
| 2010-10-07 | Now with fewer extraneous semicolons! | Owen Anderson | 1 | -1/+1 | |
| llvm-svn: 115996 | |||||
| 2010-09-06 | pull a simple method out of LICM into a new | Chris Lattner | 1 | -6/+10 | |
| Loop::hasLoopInvariantOperands method. Remove a useless and confusing Loop::isLoopInvariant(Instruction) method, which didn't do what you thought it did. No functionality change. llvm-svn: 113133 | |||||
| 2010-07-23 | Eliminate getCanonicalInductionVariableIncrement's last user and | Dan Gohman | 1 | -17/+5 | |
| eliminate it. llvm-svn: 109270 | |||||
| 2010-07-23 | Simplify this code; it can use the regular CFG utlities rather than | Dan Gohman | 1 | -13/+7 | |
| the BlockTraits abstractions. llvm-svn: 109268 | |||||
| 2010-07-21 | Fix batch of converting RegisterPass<> to INTIALIZE_PASS(). | Owen Anderson | 1 | -2/+1 | |
| llvm-svn: 109045 | |||||
| 2010-07-09 | cache result of operator* | Gabor Greif | 1 | -3/+4 | |
| llvm-svn: 107967 | |||||
| 2010-04-15 | Fix a bunch of namespace polution. | Dan Gohman | 1 | -2/+2 | |
| llvm-svn: 101376 | |||||
| 2010-03-10 | Add a DominatorTree argument to isLCSSA so that it doesn't have to | Dan Gohman | 1 | -9/+2 | |
| compute a set of reachable blocks for itself each time it is called, which is fairly frequently. llvm-svn: 98179 | |||||
| 2010-03-09 | Make isLCSSA ignore uses in blocks not reachable from the entry block, | Dan Gohman | 1 | -3/+14 | |
| as LCSSA no longer transforms such uses. llvm-svn: 98033 | |||||
| 2010-01-05 | Restore dump() methods to Loop and MachineLoop. | Dan Gohman | 1 | -0/+5 | |
| llvm-svn: 92772 | |||||
| 2009-12-18 | Add Loop contains utility methods for testing whether a loop | Dan Gohman | 1 | -1/+1 | |
| contains another loop, or an instruction. The loop form is substantially more efficient on large loops than the typical code it replaces. llvm-svn: 91654 | |||||
| 2009-12-11 | Make getUniqueExitBlocks's precondition assert more precise, to | Dan Gohman | 1 | -3/+3 | |
| avoid spurious failures. This fixes PR5758. llvm-svn: 91147 | |||||
| 2009-11-20 | Teach getSmallConstantTripMultiple about Shl operators. | Dan Gohman | 1 | -0/+5 | |
| llvm-svn: 89426 | |||||
| 2009-11-09 | Minor tidiness fixes. | Dan Gohman | 1 | -4/+3 | |
| llvm-svn: 86565 | |||||
| 2009-11-05 | Factor out the predicate code for loopsimplify form exit blocks into | Dan Gohman | 1 | -6/+8 | |
| a separate helper function. llvm-svn: 86159 | |||||
| 2009-10-20 | Fix another place that calls Loop::contains a lot to construct a sorted | Dan Gohman | 1 | -1/+4 | |
| container of the blocks and do efficient lookups. This makes isLoopSimplifyForm much faster on large loops, fixing a significant compile-time issue in builds with assertions enabled. llvm-svn: 84673 | |||||
| 2009-09-28 | Move the dominator verification code out of special code embedded within | Dan Gohman | 1 | -0/+21 | |
| the PassManager code into a regular verifyAnalysis method. Also, reorganize loop verification. Make the LoopPass infrastructure call verifyLoop as needed instead of having LoopInfo::verifyAnalysis check every loop in the function after each looop pass. Add a new command-line argument, -verify-loop-info, to enable the expensive full checking. llvm-svn: 82952 | |||||
| 2009-09-08 | Re-apply r80926, with fixes: keep the domtree informed of new blocks | Dan Gohman | 1 | -0/+10 | |
| that get created during loop unswitching, and fix SplitBlockPredecessors' LCSSA updating code to create new PHIs instead of trying to just move existing ones. Also, optimize Loop::verifyLoop, since it gets called a lot. Use searches on a sorted list of blocks instead of calling the "contains" function, as is done in other places in the Loop class, since "contains" does a linear search. Also, don't call verifyLoop from LoopSimplify or LCSSA, as the PassManager is already calling verifyLoop as part of LoopInfo's verifyAnalysis. llvm-svn: 81221 | |||||
| 2009-09-06 | Revert r80926. It causes loop unswitch assertion and slow down some JIT ↵ | Evan Cheng | 1 | -10/+0 | |
| tests significantly. llvm-svn: 81101 | |||||
| 2009-09-03 | Smallvectorize switchExitBlocks. | Dan Gohman | 1 | -1/+1 | |
| llvm-svn: 80942 | |||||
| 2009-09-03 | Add a verifyAnalysis to LoopInfo, LoopSimplify, and LCSSA form that verify | Dan Gohman | 1 | -0/+10 | |
| that these passes are properly preserved. Fix several transformation passes that claimed to preserve LoopSimplify form but weren't. llvm-svn: 80926 | |||||
| 2009-09-03 | Move getUniqueExitBlocks from LoopBase to Loop, since they depend on | Dan Gohman | 1 | -0/+68 | |
| LoopSimplify form, which is currently only available on Loops (and not MachineLoops). Also, move the code out of the header file. llvm-svn: 80923 | |||||
| 2009-08-23 | remove uses of llvm/Support/Streams.h. | Chris Lattner | 1 | -1/+0 | |
| llvm-svn: 79838 | |||||
| 2009-08-23 | Change Pass::print to take a raw ostream instead of std::ostream, | Chris Lattner | 1 | -3/+2 | |
| update all code that this affects. llvm-svn: 79830 | |||||
| 2009-08-23 | eliminate the std::ostream form of WriteAsOperand and update clients. | Chris Lattner | 1 | -0/+6 | |
| This also updates dominator related stuff. llvm-svn: 79825 | |||||
| 2009-07-17 | Replace isTrapping with a new, similar method called | Eli Friedman | 1 | -7/+2 | |
| isSafeToSpeculativelyExecute. The new method is a bit closer to what the callers actually care about in that it rejects more things callers don't want. It also adds more precise handling for integer division, and unifies code for analyzing the legality of a speculative load. llvm-svn: 76150 | |||||
| 2009-07-16 | Add an isLoopSimplifyForm() predicate, following the example of | Dan Gohman | 1 | -0/+24 | |
| isLCSSAForm(), to test whether a loop is in the form guaranteed by the LoopSimplify pass. llvm-svn: 76077 | |||||
| 2009-07-15 | Make makeLoopInvariant report whether it made any changes or not, | Dan Gohman | 1 | -4/+7 | |
| and use this to simplify more code. llvm-svn: 75722 | |||||
| 2009-07-14 | Introduce a new LoopInfo utility function makeLoopInvariant, which | Dan Gohman | 1 | -1/+62 | |
| works similar to isLoopInvariant, except that it will do trivial hoisting to try to make the value loop invariant if it isn't already. This makes it easier for transformation passes to clear trivial instructions out of the way (the regular LICM pass doesn't run until relatively late). This is code factored out of LoopSimplify and other places. llvm-svn: 75578 | |||||
| 2009-07-13 | Move isLCSSAForm, isLoopInvariant, getCanonicalInductionVariable, | Dan Gohman | 1 | -0/+178 | |
| and related functions out of LoopBase and into Loop, since they are specific to BasicBlock-based loops. This also allows the code to be moved out-of-line. llvm-svn: 75523 | |||||
| 2009-06-27 | Eliminate a layer of indirection in LoopInfo and MachineLoopInfo. | Dan Gohman | 1 | -1/+1 | |
| llvm-svn: 74394 | |||||
| 2009-06-05 | Remove some unnecessary #includes. | Dan Gohman | 1 | -1/+0 | |
| llvm-svn: 72948 | |||||
| 2009-05-01 | Change the description string of the LoopInfo pass. | Dan Gohman | 1 | -1/+1 | |
| "Construction" makes it sound like a pass that might modify the CFG to construct natural loops. llvm-svn: 70580 | |||||
| 2008-12-18 | Remove dead comments. | Evan Cheng | 1 | -3/+0 | |
| llvm-svn: 61201 | |||||
| 2008-05-06 | Remove uses of llvm/System/IncludeFile.h that are no longer needed. | Dan Gohman | 1 | -3/+0 | |
| llvm-svn: 50695 | |||||
| 2008-03-20 | These passes preserve CFG. | Devang Patel | 1 | -1/+1 | |
| This patch fixes Benchmarks/Trimaran/enc-pc1/enc-pc1 failure reported by Grawp-PIC i386 nightly tester llvm-svn: 48623 | |||||
| 2008-03-20 | Restore isCFGOnly property of various analysis passes. | Devang Patel | 1 | -1/+1 | |
| llvm-svn: 48579 | |||||
| 2008-03-19 | PassInfo keep tracks whether a pass is an analysis pass or not. | Devang Patel | 1 | -1/+1 | |
| llvm-svn: 48554 | |||||
| 2007-12-29 | Remove attribution from file headers, per discussion on llvmdev. | Chris Lattner | 1 | -2/+2 | |
| llvm-svn: 45418 | |||||
| 2007-11-27 | Make LoopInfoBase more generic, in preparation for having MachineLoopInfo. ↵ | Owen Anderson | 1 | -1/+1 | |
| This involves a small interface change. llvm-svn: 44348 | |||||
| 2007-11-15 | More templatization. | Owen Anderson | 1 | -230/+1 | |
| llvm-svn: 44158 | |||||
| 2007-11-14 | Start the process of making MachineLoopInfo possible by templating Loop. | Owen Anderson | 1 | -396/+0 | |
| llvm-svn: 44097 | |||||
| 2007-08-21 | Use SmallVector. | Devang Patel | 1 | -3/+3 | |
| llvm-svn: 41230 | |||||
| 2007-08-21 | No need to hardcode SmallVector size. | Devang Patel | 1 | -3/+3 | |
| llvm-svn: 41228 | |||||
| 2007-08-21 | Use SmallVector instead of std::vector. | Devang Patel | 1 | -3/+3 | |
