2018-10-30Base time API upon std::chronoFrank Busse
This should not change the behaviour of KLEE and mimics the old API. - functions moved from util into time namespace - uses time points and time spans instead of double - CLI arguments now have the form "3h5min8us" Changed command line parameters: - batch-time (double to string) - istats-write-interval (double to string) - max-instruction-time (double to string) - max-solver-time (double to string) - max-time (double to string) - min-query-time-to-log (double to string) - seed-time (double to string) - stats-write-interval (double to string) - uncovered-update-interval (double to string) - added: log-timed-out-queries (replaces negative max-solver-time)

2017-11-30Implemented bounded merging functionalityLukas Wölfer
2017-07-23Remove support for LLVM < 3.4Martin Nowack
Request LLVM 3.4 as minimal requirement for KLEE
2016-07-08Add deterministic allocation of memoryMartin Nowack
Deterministic allocation provides an internal allocator which mmaps memory to a fixed static address. This way, same allocation is assured across different KLEE runs for the same application assuming a deterministic searcher. In addition, this patch provides following options: -allocate-determ: switch on/off deterministic allocation -allocate-determ-size: adjust preallocated memory -null-on-zero-malloc: returns null pointer in case a malloc of size 0 was requested. According to standard, also a non-null pointer can be returned (which happens with the default glibc malloc implementation) -allocation-space: space between allocations can be adjusted. KLEE is not able to detect out-of-bound accesses which are inside another but wrong object. Due the implementation of typical allocators adjacent mallocs have space in between for management purposes. This spaces helped KLEE to detect off-by-1/2 accesses. For higher numbers, the allocation space has to be increased. -allocate-determ-start-address: adjust deterministic start address. The addres has to be page aligned. KLEE fails if it cannot acquire this address
2015-04-03Fixed issue introduce during a previous refactoring, related to field ordering.Cristian Cadar
2015-04-02Silenced some compilation warnings.Cristian Cadar
2015-04-02Removed unused fakeState field from ExecutionStateCristian Cadar
2015-04-02Removed underConstrained field, which I believe was re-introduced byCristian Cadar
mistake in the last cleanup commit.
2015-04-02[Core] Documentation and cleanupMartin Nowack
* Removed unused member ShadowObjects in ExecutionState * Added documentation of members and reorder according to categories
2014-09-19Removed code related to underConstrained, as it is unused (issue pointed out ↵Cristian Cadar
by @hpalikareva).
2014-05-29Refactoring from std::ostream to llvm::raw_ostreamMartin Nowack
According to LLVM: lightweight and simpler implementation of streams.
2013-08-27Port to LLVM 3.3Martin Nowack
Major changes are: - Switching to llvm-link to build archive files - Use GetMallocUsage instead of GetTotalMemoryUsage (be aware of bug in LLVM 3.3 http://llvm.org/bugs/show_bug.cgi?id=16847) - intrinsic library functions like memcpy/mov/set use weak linkage to be replaced by e.g. uclibc functions - rewrote linking with library - enhanced MemoryLimit test case to check if mallocs were successful
2012-01-18Nice patch by Gang Hu, Heming Cui and Junfeng Yang fixing a memoryCristian Cadar
leak in KLEE. From Gang Hu: "The memory leak is caused by two reasons. First, the MemoryObject objects are not freed, until the MemoryManager is destroyed. Second, when KLEE allocates a non-fixed MemoryObject object, KLEE also allocates a block of memory which is the same as the object's size. This block of memory is never freed. So, this patch generally does reference counting on the MemoryObject objects, and frees them as soon as the reference count drops to zero." Many thanks to Paul Marinescu as well, who tested this patch thoroughly on the Coreutils benchmarks. On 1h runs, the memory consumption typically goes down by 1-5%, but some applications which see more significant gains. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@148402 91177308-0d34-0410-b5e6-96231b3b80d8

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

2009-06-02Use 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
2009-05-21Initial 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
