2013-07-11Bug fix by Jonathan Neuschäfer: "Without this patchCristian Cadar
NotExpr::computeHash() will have a local variable with the name "hashValue" and assign the newly computed hash to that instead of the member variable with the same name that should be set by the computeHash method of every Expr subclass." git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@186102 91177308-0d34-0410-b5e6-96231b3b80d8
2013-05-08Patch by Dan Liew: "Renamed ExprSMTLIBPrinter method mangleQuery() to ↵Cristian Cadar
negateQueryExpression() to make it clear what it does." git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@181445 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-24Patch by Dan Liew: "Moved PrintContext class out of ExprPrinter.cpp soCristian Cadar
it can be used by other classes. It has also been improved so it can be used with the soon to be added ExprSMTLIBPrinter classes." git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@166555 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-24Patch by Dan Liew: " Modified ConstantExpr::toString() to take anCristian Cadar
optional radix (base e.g. 2,10,16). This will be needed by the ExprSMTLIBPrinter that will soon be added." git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@166553 91177308-0d34-0410-b5e6-96231b3b80d8

arrays from the Array and UpdateNode classes. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@166214 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

2011-04-23Patch 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
