2009-06-14Remove the (A < constant) => (A == 0 || A == 1 ... || A == constant - 1)Daniel Dunbar
optimization, its not the kind of thing we should always be performing. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73340 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
2009-06-14Fail with an exec error on large (> 64-bit) floating point ops.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73330 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
2009-06-14More ConstantExpr tweaks.Daniel Dunbar
- We can safely assume for now that array indices are within 32-bits (we will enforce this even on 64-bit targets). - We can also safely assume that address fit in 64-bits. - Always look up function pointers using 64-bits. - Protect a few other places by explicit checks that the type is <= 64-bits, when we can fallback to a safe path. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73328 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-14Change AddressSpace::resolveOne to take a ConstantExpr directly (and to allowDaniel Dunbar
64-bit addresses). git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73327 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
2009-06-13Switch to using constant arrays for non-symbolic objects.Daniel Dunbar
- Currently uses a dumb implementation which keeps the old flushing architecture, but converts to a constant array when the first ReadExpr is created. - Temporary --use-constant-arrays switch can be used to disable for testing. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73313 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-13pcregrep should run with klee-libc.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73312 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
2009-06-13Create new ObjectState constructor for explicitly creating symbolic objects.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73308 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-13Fix for the issue reported and diagnosed by Seungbeom, where KLEE wasCristian Cadar
skipping forks without reporting it. Added a warning the first time a fork is skipped for each of four different reasons. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73307 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-13Add CBE'ified version of pcregrep.Daniel Dunbar
- Cleaned up enough to build on Darwin & Linux. - I don't really care to have too many programs in the test suite, but this works until we have some better place for them. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73303 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
2009-06-13Removed bits of grammar dealing with quantifiers.Cristian Cadar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73280 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-13Support for parsing SMTLIB headers. Cristian Cadar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73278 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-13Changed SMTParser to return the parsed QueryCommand.Cristian Cadar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73277 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-12Removed parser_temp.h. Adapted the code to use SMTParser directly. Cristian Cadar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73215 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-12Removed unused file.Cristian Cadar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73214 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-10Move declaration of vc_DeleteExpr outside of function.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73173 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-10Updated the SMT test driver. Other small changes to parser_temp.h andCristian Cadar
smtlib.y. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73167 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-10Removed CVC3's Parser class. Cristian Cadar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73166 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-10Wrote a new SMTParser that inherits from klee::expr::Parser.Cristian Cadar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73165 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-10(Missed save) Move Array construction out of MemoryObject into ObjectState.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73163 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
2009-06-10Use Arrays instead of MemoryObject where possible.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73160 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-10Fix a bug in the logging solver which was printing the expression in aDaniel Dunbar
getInitialValues query in the wrong place. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73159 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-10Added a temporary driver to test the parser.Cristian Cadar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73155 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-10Changed expression nodes to be ExprHandle (instead of ExprHandle*), andCristian Cadar
added a quick hack to change Bison unions to structs. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73154 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-09Use env instead of hard coding python path.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73142 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
2009-06-09Do not compile SMT parser by default. Removed automatically generatedCristian Cadar
parser files: We really don't want SVN to keep track of changes in these files while working on the parser. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73132 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-09Made expression nodes int the SMT parser be pointers to ExprHandle.Cristian Cadar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73131 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
2009-06-09Switch Array* print-outs to use name instead of ID, and update a fewDaniel Dunbar
constructors I missed. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73127 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-09Use Array* to map objects instead of id.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73126 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
2009-06-09Remove unnecessary include.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73123 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-09Set svn:ignore on lib/SMT/{Debug,Release}Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73122 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-09Quick hack to build SMT LLVM style.Daniel Dunbar
- I don't want to make proper bison/flex rules, and eventually I think we should just check in the generated files since we don't expect them to change, so for now just build the files in the src directory. Eventually we will want to disable these rules so that it works for people who don't have bison/flex. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73121 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-09Remove exception.h and parser_exception.hDaniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73111 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-09Kill off uses of C++ exceptions.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73110 91177308-0d34-0410-b5e6-96231b3b80d8
