git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73872 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-22Store ConstantExpr's value as an APInt.Daniel Dunbar

2009-06-22Add ConstantExpr::toString (instead of using getConstantValue()).Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73870 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-15Support partial folding for Add in new constant folding builder.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73363 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-14Add NonConstantExpr, so it is possible to statically type an expression that isDaniel Dunbar
known to be not-constant. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73352 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-14Rename FoldingExprBuilder -> SimplifyingExprBuilderDaniel Dunbar
Also, start printing query # with -print-ast (for testing purposes). git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73350 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-14Kill off ExtractExpr::createByteOff.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73348 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-14Use ExprBuilder for constructing expressions in the Parser.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73345 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-14Add ExprBuilder base class, and start of implementations.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73339 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-14More ConstantExpr cleanup.Daniel Dunbar
- Change Executor::evalConstant to return ConstantExpr. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73337 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-14Remove some unused functionality.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73329 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-14Add ConstantExpr::{getLimitedValue,getZExtValue}.Daniel Dunbar
- For use in situations where the range of the constant is known to fit in a uint64 (or smaller), or the extra bits don't matter. - No (intended) functionality change. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73326 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-14Rewrite ImpliedValue to use ConstantExpr operations.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73325 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-14Add several ConstantExpr utility functions and move clients over.Daniel Dunbar
- Reducing uses of getConstantValue() so we can move to arbitrary precision constants. - No (intended) functionality change. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73324 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-14Add constant folding operations to ConstantExpr.Daniel Dunbar
- No (intended) functionality change. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73322 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-13Reverted last change that added createIff. Since we only handleCristian Cadar
bitvectors, we can just use Eq. The parser can distinguish between boolean formulas and bitvector terms. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73309 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-13Added a helper function to construct IFF expressions.Cristian Cadar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73283 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-10Move Array construction out of MemoryObject into ObjectState.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73162 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-10Change ExecutionState::symbolics to include both the MemoryObject and theDaniel Dunbar
symbolic Array. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73161 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-09More constant Array support.Daniel Dunbar
- The are parsed, printed, and solved now. - Remove some members of ArrayDecl which are only duplicates of Array members. - KLEE still doesn't create these, but you can write them by hand. The EXE style constant array optimization for STP (turning the initial writes into asserts) is now only a stones throw away, but I need to leave something fun to do tomorrow. :) git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73133 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-09Add initial support for constant Arrays.Daniel Dunbar
- This doesn't actually start using them, it just attempts to update all clients to do the right thing in the presence of them. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73130 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-09Remove Array::object.Daniel Dunbar
- The sole remaining client was IVC, which is currently disabled for other correctness issues. I patched it to compile and left a FIXME that we will have to resolve this before we can reenable IVC. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73129 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-09Remove Array::id.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73128 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-09Add Array::name field, initialized but not used for anything yet.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73125 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-09Kill off UpdateList::isRooted flag.Daniel Dunbar
- The right way to handle this is by using constant arrays, where the semantics are easier to define and implement. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73124 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-08Kill off Concat::is[248]ByteConcat, and fix FastCexSolver for this case.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73049 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-08Add klee::createDummySolver, the dummy solver always fails.Daniel Dunbar
- Useful as an alternative backend to STP for testing. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73048 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-07Make sure that ExprEvaluator will fold constant expressions (klee never createsDaniel Dunbar
these, but the parser can). git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73033 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-07Implement array declarations.Daniel Dunbar
- Printing current prints all declarations, and we allow redefinition, since the printer doesn't know what has already been printed. - Names don't print right yet, since the Array* object doesn't have the name. - Various things are unsupported. o Array domain/range must be w32/w8. o Concrete initializers for arrays are unsupported. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73026 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-05Support the extended query command syntax.Daniel Dunbar
- There are two optional lists following the constraints and the query expression. The first is a list of expressions to give values for and the second is a list of arrays to provide values for. - Update ExprPPrinter to accept extra arguments to print these arguments. - Add Parser support. - Add more ArrayDecl support. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72938 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-05Add Expr::is{Zero,True,False} methods.Daniel Dunbar
- These are too convenient to live without. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72937 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-05llvm::Casting support for Kleaver AST nodes.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72931 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-05Clean up a number of unused variable warnings when building w/oDaniel Dunbar
asserts. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72924 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-05Expr::print shouldn't introduce line breaks or extra formatting.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72921 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Make ConstantExpr's value and constructor private.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72863 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Sink getConstantValue into ConstantExpr.Daniel Dunbar
- Propogate ConstantExpr to various places, or cast as appropriate. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72862 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Change Solver::getValue to make explicit that result is a ConstantExpr.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72860 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Finish removing uses of Expr::isConstant.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72859 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Start removing uses of Expr::isConstant.Daniel Dunbar
- These should use cast<>, isa<>, or dyn_cast<> as appropriate (or better yet, changed to use ref<ConstantExpr> when the type is known). git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72857 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Change ConstantExpr::{alloc,create} to return a ref<ConstantExpr>Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72853 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Use dyn_cast<> instead of dyn_ref_cast.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72847 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Use cast<> instead of static_ref_cast.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72845 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Implement simplify_type for ref<>Daniel Dunbar
- This allows dyn_cast<> and friends to be applied to a ref. For example, if (ConstantExpr *CE = dyn_cast<ConstantExpr>(foo)) { ... do something with CE ... } - This makes working with ref<Expr>s much more convenient, with the downside that it hides a potentially dangerous operation. Since the result is not itself a ref<>; clients are resposible for making sure the returned value is only used inside the lifetime of some other ref<>. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72839 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Expr: Add LLVM style casting support instead of requiring RTTI.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72829 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Move isConstant from ref<> to Expr::Daniel Dunbar
- Ref.h is now freestanding. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72824 91177308-0d34-0410-b5e6-96231b3b80d8
