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
2009-06-04Change ConstantExpr::{alloc,create} to return a ref<ConstantExpr>Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72853 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Use dyn_cast<> instead of dyn_ref_cast.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72847 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Use cast<> instead of static_ref_cast.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72845 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Implement simplify_type for ref<>Daniel Dunbar
- This allows dyn_cast<> and friends to be applied to a ref. For example, if (ConstantExpr *CE = dyn_cast<ConstantExpr>(foo)) { ... do something with CE ... } - This makes working with ref<Expr>s much more convenient, with the downside that it hides a potentially dangerous operation. Since the result is not itself a ref<>; clients are resposible for making sure the returned value is only used inside the lifetime of some other ref<>. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72839 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-04Expr: Add LLVM style casting support instead of requiring RTTI.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72829 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
2009-06-03Remove ref<>'s constant Expr optimization.Daniel Dunbar
- This simplifies what users of the Expr language need to deal with, and paves the way for arbitrary bit-width constant support. - The downside is that concrete interpretation just got *way* slower (2-3x). However, I have a plan for fixing this that should give us the best of both worlds in terms of performance & simplicity. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72753 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-03Update ConstantExpr::fromMemory to return a ref<Expr>.Daniel Dunbar
- This function should go away... git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72751 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-03Remove a usage of the direct ref<Expr> constructor that I missed.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72750 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-03Inline Expr::hashConstant into callers.Daniel Dunbar
(Extraneous uses are going away shortly) git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72749 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
2009-05-28Small changes to silence some gcc warnings.Cristian Cadar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72518 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-25Add include for uint64_t, needed when building withDuncan Sands
gcc-4.4. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72380 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
2009-05-22Add "name" argument to klee_make_symbolic, and kill off klee_make_symbolic_name.Daniel Dunbar
- For compatibility we still accept 2 argument form of klee_make_symbolic, but this will go away eventually. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@72265 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
