2009-08-17Update for LLVM API change.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@79217 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-03Fix computation of GetElementPtr offset for 64-bit targets.Daniel Dunbar
- Precomputed constants were being truncated to 32-bits! - This was actually the problem with new[]/delete[], I failed to look at the generated code for new[] to realize that the compiler is generating the offset pointer, not the runtime library. - All tests now pass on x86-64! git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@77930 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-02Print allocation info for adjacent objects in out-of-bounds message.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@77922 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-01Implement va_arg handling for x86_64.Daniel Dunbar
- Based on a patch by Vladimir Kuznetsov! - x86_64 has a complicated calling convention for va_args; instead of dealing with this, this patch uses a clever workaround by initializing the va_list structure so that the callee believes all arguments were passed in the stack save area. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@77819 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-01KLEE64: Fix initialization of ctype_ externals.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@77816 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-29Multiply for alloca & malloca instructions may need to coerce index expressionDaniel Dunbar
to target pointer width. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@77428 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-28KLEE64: When binding GetElementPtr constants, do evaluation in pointer width ofDaniel Dunbar
target. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@77310 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
2009-07-25(llvm up) Update for API changes.Daniel Dunbar
- This dance is getting old. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@77029 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-15[llvm up] Update for LLVM TOT changes.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@75826 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-12Simplify.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@75425 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-10Replaced createNot() by createIsZero() and "Not" macro by "Nz". Cristian Cadar
Not will become bitwise not. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@75224 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-27Start move to using APFloat (support long double).Daniel Dunbar
- Incomplete, still have to move some conversion operations. - Also, there isn't support yet for copying long double values to native memory. - Still, should be a monotonic improvement and we are no longer faking long double support. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@74363 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-26More large integer support.Daniel Dunbar
- Allow constructing a ConstantExpr from an APInt, too painful otherwise. - Parser support for large integers. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@74278 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-25Flesh out support for arbitrary bit widths in some key places (STP & constantDaniel Dunbar
creation). - Not used yet. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@74142 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-24Update for LLVM API change.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@74075 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 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
2009-06-14More 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
2009-06-14Add 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
2009-06-13Create 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
2009-06-10Change 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
2009-06-09Remove 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
2009-06-05Clean 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
2009-06-05(llvm up) Update klee for introduction of f{add,sub,mul} instructions.Daniel Dunbar
- Please update & rebuild LLVM. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72919 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
2009-06-04Start 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
2009-06-03Update a few things that got forgotten in the great "bout" to "ktest"Daniel Dunbar
renaming of '08. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72748 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
2009-06-01Kill off klee_malloc_n, we don't want to support this.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72693 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
2009-05-23Changed bout to ktest. Kept "BOUT\n" as the header of test files, for ↵Cristian Cadar
backward compatibility. Also changed KLEE_RUNTEST to KTEST_FILE. Updated tutorial-1. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72312 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
