2014-12-12Print nested let-abbreviations in ExprSMTLIBPrinterRaimondas Sasnauskas
This patch introduces nested let-abbreviations in the ExprSMTLIBPrinter to reduce the size of the SMTLIBv2 queries and the corresponding processing time (bugfix for #170). The current implementation of the let abbreviation mode does not consider expression intra-dependencies and prints all abbreviations in the same let scope. For a (simplified) example, it prints (assert (let ( (?B1 (A + B)) (?B2 (A + B + C)) ) (= ?B1 ?B2) ) ). This is extremely inefficient if the expressions (and there many of these!) extensively reuse their subexpressions. Therefore, it's better to print the query with nested let-expressions by reusing existing expression bindings in the new let scope: (assert (let ( (?B1 (A + B)) ) (let ( (?B2 (?B1 + C)) ) (= ?B1 ?B2) ) ) ). This patch adds a new function ExprSMTLIBPrinter::scanBindingExprDeps() that scans bindings for expression dependencies. The result is a vector of new bindings (orderedBindings) that represents the expression dependency tree. When printing in the let-abbreviation mode, the new code starts with abbreviating expressions that have no dependencies and then gradually makes these new bindings available in the upcoming let-scopes where expressions with dependencies reuse them. The effect of nested let-abbreviations is comparable to :named abbreviations. However, the latter mode is not supported by the majority of the solvers.
2014-12-02The printing of constraints and the QueryExpr have been merged into aDan Liew
single method with two different implementations. There is one version of this method for human readability (printHumanReadableQuery()) and a version for machine consumption (printMachineReadableQuery()). The reason for having two versions is because different behaviour is needed in different scenarios * In machine readable mode the entire query is printed inside a single ``(assert ...)``. This is done to allow ``(let ...)`` to abbreviate as much as possible. * In human readable mode each constraint and query expression is printed inside its own ``(assert ...)`` unless the abbreviation mode is ABBR_LET in which case all constraints and query expr are printed inside a single ``(assert ...)`` much like in the machine readable mode Whilst I was here I also fixed a bug handling identation when printing ``(let ...)`` expressions in printAssert()
2014-12-02Implement :named and let abbreviation modes in ExprSMTLIBPrinterRaimondas Sasnauskas
* Set the default abbreviation mode to let (ExprSMTLIBPrinter::ABBR_LET) * Remove the now defunct ExprSMTLIBLetPrinter * Improve performance of ExprSMTLIBPrinter::scan() by keeping track of visited Expr to avoid visiting them again * Rename ExprSMTLIBPrinter::printQuery() to ExprSMTLIBPrinter::printQueryExpr()

2014-01-20Remove the last remnants (I think) of DejaGNU. Goodbye!Dan Liew
Say hello to our new friend, llvm-lit :)
2014-01-20Fixed Expr/Parser/Simplify.pc test for llvm-lit. Escaped quote issue.Dan Liew
2014-01-20Fixed Expr/Parser/MultiByteReads.pc test.Dan Liew
2014-01-20Fixed Expr/Parser/ConstantFolding.pc test for llvm-lit (this probablyDan Liew
breaks DejaGNU tests). The issue is that in Tcl the quote needs escaping but for llvm-lit we don't need to do this. We should move to using the LLVM FileCheck tool instead of grep!
2012-10-24Patch by Dan Liew: "Added primitive test that checks kleaver's newCristian Cadar
-print-smt option. Improved Feature/ExprLogging.c test: - Now (primitive) checks the result of -write-smt2s - Now (primitive) checks the result of -write-pcs - Now (primitive) checks the result of -write-cvcs" git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@166569 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-15Fixed two test cases. Cristian Cadar
The failing test case is actually (query [false] false), which should return VALID, but currently returns INVALID. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@75747 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
2009-06-07Implement 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

2009-06-07Eliminate 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
2009-06-05Support 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 evaluation support to kleaver (now the default).Daniel Dunbar
- Currently only handles validity queries. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72933 91177308-0d34-0410-b5e6-96231b3b80d8

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

2009-05-21Initial KLEE checkin.Daniel Dunbar
- Lots more tweaks, documentation, and web page content is needed, but this should compile & work on OS X & Linux. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72205 91177308-0d34-0410-b5e6-96231b3b80d8
