2009-09-01Update for LLVM ostream changes.Daniel Dunbar
- Includes patch by Michael Stone! git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@80665 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-28KLEE64: Regardless of the target, offsets in the memory subsystem are 32-bits. IDaniel Dunbar
don't think anyone is going to be doing symbolic execution with > 4GB buffers any time soon, and this is slightly simpler. - We know pass about half of KLEE's test suite on Darwin x86_64. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@77309 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-28Move Machine constants into Context object, initialized based on the targetDaniel Dunbar
data. - This is the first step towards having KLEE be fully target independent, its not particularly beautiful but its expedient. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@77306 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-25(llvm up) Update for llvm::Value getName() change.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@77049 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-26Simplify read/write code.Daniel Dunbar
- Get rid of unnecessary special cases. - Support read/write of large integers. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@74286 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
2009-06-14More 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
2009-06-14Add 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
2009-06-14Add 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
2009-06-13Create 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
2009-06-10Move 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
2009-06-09Kill 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
2009-06-05Clean 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
2009-06-04Finish 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
2009-06-04Move 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
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
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
