2011-10-17Fix some -Wunused-variable warnings.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@142310 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-24Applied patch by Leandro Sales that makes Kleaver compatible with theCristian Cadar
recent changes to array names. Modified FastCexSolver.pc to catch this issue. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@135896 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-20Deprecate LLVM_VERSION_MAJOR and LLVM_VERSION_MINOR in favour ofPeter Collingbourne
version codes. This makes the preprocessor-based version tests more concise and less error prone. Also, fix the version tests in lib/Expr/Parser.cpp (immutable zext and trunc were introduced in LLVM 2.9); now 2.9 passes "make test". git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@135583 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-18Maintain an equivalence set during comparison operationsPeter Collingbourne
This results in a significant speedup of certain comparisons involving large partially shared expression trees. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@131585 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-18Support for arbitrary sized types in ConstantExpr::fromMemoryPeter Collingbourne
git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@131583 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-23Patch by arrowdodger ↵Cristian Cadar
(http://keeda.stanford.edu/pipermail/klee-dev/2011-April/000617.html) for compiling KLEE with the latest LLVM changes. Tested against LLVM 2.7 and 2.8. The AsmAddresses test fails in 2.8 unless assertions are explicitely enabled (--enable-assertions). git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@130065 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

2009-06-27Start 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
2009-06-25Kill off last getConstantValue uses.Daniel Dunbar
- ConstantExpr should now fully support arbitrary width operations. - Still numerous holes in parsing, solver, etc. to plug. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@74151 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@74149 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@74148 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73872 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-22Store ConstantExpr's value as an APInt.Daniel Dunbar

2009-06-14The expansion for Read{MSB,LSB} needs to continue to use the folding methods,Daniel Dunbar
otherwise we build expressions that won't be matched later when we print them. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@73347 91177308-0d34-0410-b5e6-96231b3b80d8

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

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
2009-06-14Add 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
2009-06-13Reverted 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
2009-06-13Added 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
2009-06-10Move 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
2009-06-10(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
2009-06-09More 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
2009-06-09Add 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
