2009-06-08Removed support for the PL and Lisp languages.Cristian Cadar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73060 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-08Added CVC3's parser for the SMT-LIB grammar. Cristian Cadar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73059 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-08FastCexSolver: Start implementing exact value propogation.Daniel Dunbar
- So far this just propogates obvious equalities and reads. For example, FastCexSolver can now prove that: -- array arr219[3] : w32 -> w8 = symbolic (query [(Eq 235 N0:(Read w8 0 arr219))] (Eq 235 N0)) -- is valid. Even though this is very basic, it is good enough to solve ~50% of the valid queries on pcresymtest-[34].pc (total reduction in # of queries is ~25%). Unfortunately, this only gives a 1-2% speedup, which is disappointing, but there is a lot more we can do. I'm a little surprised the speedup is so low, this may be an indicator that there are some other things going on, for example perhaps the STP expr construction cost for arrays is very high, and we inevitably will end up paying this unless we solve so many queries that some arrays never ever make it to STP. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73058 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-08FastCexSolver: Stub out infrastructure for propogating exact values & provingDaniel Dunbar
validity. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73055 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-08FastCexSolver: Add exact value contents to CexObjectData.Daniel Dunbar
- The exact contents are a conservative approximation for the values of each array location, to be used for proving valid queries. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73054 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-08FastCexSolver: Rename forceExprTo* to propogatePossible*Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73053 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-08FastCexSolver: Lazily initialize object values and kill off ObjectFinder class.Daniel Dunbar
Also, explicitly manage the object data to avoid copy overhead. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73051 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
2009-06-08Cleanup FastCexSolver:Daniel Dunbar
- Make CexObjectData members private. - Use std::vector instead of allocating memory by hand. - Factor out method which does the propogation from the various Solver routines. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73047 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-08Fix a mistake in previous commit to turn asserts -> parse errors.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73046 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
2009-06-07Diagnose some more syntax errors instead of crashing.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73032 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-07Make sure to include arrays to be evaluated in the set of used arrays.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73030 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
2009-06-07Make sure to make up a valid VersionResult on failures.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73019 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-07Eliminate anonymous versions.Daniel Dunbar
- For now, this means the isRooted flag for arrays isn't propogated to the kquery language. We should figure out how to do this, but allow anonymous versions isn't the right way. Also, improved the error on invalid writes a bit. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73018 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-06Document the KQuery language.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72997 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

2009-06-04Sink 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

2009-06-04Start 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

2009-06-04Fixed a bug in Kleaver's parser: APInt does not allow "truncation" toCristian Cadar
the same width. Added a test case that was previously triggering an assert violation. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72850 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72841 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Fixed the code dealing with ReadLSB/ReadMSB, which was currentlyCristian Cadar
broken (it was written for n-ary Concats, but now we have binary Concats.) git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72840 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-03Kill off specialized ref<> forwarding methods, in the interest of making it aDaniel Dunbar
more standard reference counting wrapper. - The only interesting changes here are in Ref.h, everything else is just updating foo.method to use foo->method instead. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72777 91177308-0d34-0410-b5e6-96231b3b80d8

- This function should go away... git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72751 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-02Use ConstantExpr::alloc instead of ref<Expr> directlyDaniel Dunbar
- The "constant optimization" embedded inside ref<Expr> is going away. - No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72730 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-01Modify eval() to return a cell reference instead of its contents.Daniel Dunbar
Add get{Dest,Argument}Cell for computing the cell to store instructions results and arguments into, respectuvely. Prep for moving fast path constant evaluation out of the Expr libraary itself. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72692 91177308-0d34-0410-b5e6-96231b3b80d8
