| * | Resurrect r1.25. | Nick Lewycky | 2006-10-25 | 1 | -117/+154 | |
| | | | | | | | Fix and comment the "or", "and" and "xor" transformations. llvm-svn: 31189 | |||||

| | | | | | llvm-svn: 31184 | |||||
| * | Revert back to r1.21, which was the last revision of predsimplify that | Chris Lattner | 2006-10-24 | 1 | -134/+109 | |
| | | | | | | | passes llvm-gcc bootstrap. llvm-svn: 31146 | |||||
| * | Remove the Backwards operation. Resolving now works at the time when a | Nick Lewycky | 2006-10-23 | 1 | -90/+102 | |
| | | | | | | | | property is added by running through the list of uses of the value and adding resolved properties to the property set. llvm-svn: 31126 | |||||

| | | | | | llvm-svn: 31121 | |||||
| * | Handle "if ((x|y) != 0)" for ints like we do for bools. Fixes missed | Nick Lewycky | 2006-10-22 | 1 | -10/+13 | |
| | | | | | | | optimization opportunity pointed out by Chris Lattner. llvm-svn: 31118 | |||||
| * | AllocaInst can't return a null pointer. Fixes missed optimization | Nick Lewycky | 2006-10-22 | 1 | -0/+6 | |
| | | | | | | | opportunity pointed out by Andrew Lewycky. llvm-svn: 31115 | |||||
| * | Replace custom dispatch code with two uses of InstVisitor. Improves | Nick Lewycky | 2006-10-12 | 1 | -93/+113 | |
| | | | | | | | compile-time performance. llvm-svn: 30896 | |||||
| * | Simplify logic further. | Nick Lewycky | 2006-10-03 | 1 | -17/+8 | |
| | | | | | | | | Ensure that we copy KnownProperties before calling visitBasicBlock, else we may leak properties into blocks where they don't belong. llvm-svn: 30705 | |||||
| * | Simplify, now that predsimplify depends on break-crit-edges. | Nick Lewycky | 2006-10-03 | 1 | -26/+8 | |
| | | | | | | | Fix SwitchInst where dest-block is the same as one of the cases. llvm-svn: 30700 | |||||
| * | Move break-crit-edges before the predicate simplifier. Allows us to | Nick Lewycky | 2006-10-03 | 1 | -7/+3 | |
| | | | | | | | optimize in more cases. llvm-svn: 30699 | |||||
| * | Eliminate ConstantBool::True and ConstantBool::False. Instead, provide | Chris Lattner | 2006-09-28 | 1 | -40/+33 | |
| | | | | | | | ConstantBool::getTrue() and ConstantBool::getFalse(). llvm-svn: 30665 | |||||
| * | Style changes only. Remove dead code, fix a comment. | Nick Lewycky | 2006-09-23 | 1 | -11/+4 | |
| | | | | | llvm-svn: 30588 | |||||
| * | Don't rewrite ConstantExpr::get. | Nick Lewycky | 2006-09-21 | 1 | -44/+20 | |
| | | | | | llvm-svn: 30552 | |||||
| * | Once we're down to "setcc type constant1, constant2", at least come up | Nick Lewycky | 2006-09-20 | 1 | -18/+14 | |
| | | | | | | | with the right answer. llvm-svn: 30550 | |||||
| * | Use a total ordering to compare instructions. | Nick Lewycky | 2006-09-20 | 1 | -87/+101 | |
| | | | | | | | Fixes infinite loop in resolve(). llvm-svn: 30540 | |||||
| * | Walk down the dominator tree instead of the control flow graph. That means | Nick Lewycky | 2006-09-18 | 1 | -150/+90 | |
| | | | | | | | | that we can't modify the CFG any more, at least not until it's possible to update the dominator tree (PR217). llvm-svn: 30469 | |||||
| * | Add some more consistency checks. | Nick Lewycky | 2006-09-13 | 1 | -1/+20 | |
| | | | | | llvm-svn: 30305 | |||||
| * | Fix unionSets so that it can merge correctly. | Nick Lewycky | 2006-09-13 | 1 | -22/+34 | |
| | | | | | llvm-svn: 30304 | |||||
| * | Erase dead instructions. | Nick Lewycky | 2006-09-13 | 1 | -2/+3 | |
| | | | | | llvm-svn: 30298 | |||||
| * | Skip the linear search if the answer is already known. | Nick Lewycky | 2006-09-11 | 1 | -20/+22 | |
| | | | | | llvm-svn: 30251 | |||||
| * | Replace EquivalenceClasses with a custom-built data structure. Many common | Nick Lewycky | 2006-09-10 | 1 | -133/+259 | |
| | | | | | | | | | | operations (like findProperties) should be faster, at the expense of unionSets being slower in cases that are rare in practise. Don't erase a dead Instruction. This fixes a memory corruption issue. llvm-svn: 30235 | |||||
| * | Improve handling of SelectInst. | Nick Lewycky | 2006-09-02 | 1 | -31/+44 | |
| | | | | | | | | | Reorder operations to remove duplicated work. Fix to leave floating-point types out of the optimization. Add tests to predsimplify.ll for SwitchInst and SelectInst handling. llvm-svn: 30055 | |||||
| * | Don't confuse canonicalize and lookup. Fixes predsimplify.reg4.ll. Also | Nick Lewycky | 2006-09-01 | 1 | -21/+20 | |
| | | | | | | | corrects missing optimization opportunity removing cases from a switch. llvm-svn: 30009 | |||||
| * | Properties where both Values weren't in the union (as being equal to | Nick Lewycky | 2006-08-31 | 1 | -24/+18 | |
| | | | | | | | | | another Value) weren't being found by findProperties. This fixes predsimplify.ll test6, a missed optimization opportunity. llvm-svn: 29991 | |||||
| * | Move to using the EquivalenceClass ADT. Removes SynSets. | Nick Lewycky | 2006-08-30 | 1 | -165/+92 | |
| | | | | | | | | | | If a branch's condition has become a ConstantBool, simplify it immediately. Removing the edge saves work and exposes up more optimization opportunities in the pass. Add support for SelectInst. llvm-svn: 29970 | |||||
| * | Add PredicateSimplifier pass. Collapses equal variables into one form | Nick Lewycky | 2006-08-28 | 1 | -0/+744 | |
| and simplifies expressions. This implements the optimization described in PR807. llvm-svn: 29947 | ||||||
