* Rework InstrTypes.h so to reduce the repetition around the NSW/NUW/ExactChris Lattner2011-02-091-140/+58
| | | | | | | | | | | | | | | | | | | | versions of creation functions. Eventually, the "insertion point" versions of these should just be removed, we do have IRBuilder afterall. Do a massive rewrite of much of pattern match. It is now shorter and less redundant and has several other widgets I will be using in other patches. Among other changes, m_Div is renamed to m_IDiv (since it only matches integer divides) and m_Shift is gone (it used to match all binops!!) and we now have m_LogicalShift for the one client to use. Enhance IRBuilder to have "isExact" arguments to things like CreateUDiv and reduce redundancy within IRbuilder by having these methods chain to each other more instead of duplicating code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125194 91177308-0d34-0410-b5e6-96231b3b80d8

* FixedNumOperandTraits and VariadicOperandTraits assumed that, given aJay Foad2011-01-111-3/+5
| | | | | | | | | | | "this" pointer for any subclass of User, you could static_cast it to User* and then reinterpret_cast that to Use* to get the end of the operand list. This isn't a safe assumption in general, because the static_cast might adjust the "this" pointer. Fixed by having these OperandTraits classes take an extra template parameter, which is the subclass of User. This is groundwork for PR889. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123235 91177308-0d34-0410-b5e6-96231b3b80d8

* Include optional subclass flags, such as inbounds, nsw, etc., in theDan Gohman2009-09-041-6/+21
| | | | | | | | | | | | | | | | | | Constant uniquing tables. This allows distinct ConstantExpr objects with the same operation and different flags. Even though a ConstantExpr "a + b" is either always overflowing or never overflowing (due to being a ConstantExpr), it's still necessary to be able to represent it both with and without overflow flags at the same time within the IR, because the safety of the flag may depend on the context of the use. If the constant really does overflow, it wouldn't ever be safe to use with the flag set, however the use may be in code that is never actually executed. This also makes it possible to merge all the flags tests into a single test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80998 91177308-0d34-0410-b5e6-96231b3b80d8

* Rename Instruction::isIdenticalTo to Instruction::isIdenticalToWhenDefined,Dan Gohman2009-08-251-7/+0
| | | | | | | | | | | | | | | | | and introduce a new Instruction::isIdenticalTo which tests for full identity, including the SubclassOptionalData flags. Also, fix the Instruction::clone implementations to preserve the SubclassOptionalData flags. Finally, teach several optimizations how to handle SubclassOptionalData correctly, given these changes. This fixes the counterintuitive behavior of isIdenticalTo not comparing the full value, and clone not returning an identical clone, as well as some subtle bugs that could be caused by these.
