2020-09-26Replace llvm::CallSite with llvm::CallBase on LLVM 8+Lukas Zaoral
This is in preparation for LLVM 11 as the llvm:CallSite class has been removed.
2020-08-19DiscretePDF: use IDs instead of pointers (see PR #739)Frank Busse
2020-07-30introduce --rng-initial-seed=<unsigned>Frank Busse
* move global theRNG into Executor * pass theRNG via ctor to searchers * remove some type warnings from RNG.cpp Fixes #1023.
2020-07-01Use constraint sets and separate metadata for timing solver invocationMartin Nowack
Decouple ExecutionState from TimingSolver Instead of providing an execution state to the timing solver use a set of constraints and an additional object for metadata. Fixes: * correct accounting of metadata to a specific state * accounting of all solver invocations (e.g. solver-getRange was not accounted) * allows to invoke the solver without a state (avoids costly copying of states/constraints)

2020-06-29Revert "refactor PTree: use unique_ptr"Timotej Kapus
This reverts commit 0aed7731210d0eb41c0ea767edb8067130cf6252.

appropriate existing directories and a new directory Statistics; a few missing renames.

2019-12-12[Searchers] Remove weight from es, add nurs_depthTimotej Kapus
Having both weight and depth in execution state is wasteful, therefore this patch removes weight. The nurs:depth searcher is replaced by nurs:rp, which uses pow to compute the weight A new nurs:depth searcher is introduced that biases the search with depth, making it the only other searcher that prefers to go deep (similar to dfs).

2019-09-20refactor PTree: remove split(), add attach() methodFrank Busse
2019-03-21drop support for LLVM <= 3.7Julian Büning
2019-03-16Added support for disabling --batch-instructions and --batch-time by setting ↵Cristian Cadar
them to 0
2019-03-12time: add double type for span multiplicationsFrank Busse
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)

MartinNowack-fix_bfs2
2016-11-09Fix BFS searcherMartin Nowack
For performance reasons, if KLEE branches, one state is reused and it is progressed by adding new constraints. Make sure both new states end up at the end of the BFS searcher queue.
2016-11-08add nicer error messages for --use-merge and add explanation why it ↵Hoang M. Le

2016-09-26Modified logging information to steer the usage of klee_message, ↵Andrea Mattavelli

Deterministic adding/removing of states.

2014-09-14[LLVM3.5] Update for move of CFG.h into IR.Daniel Dunbar
- Mostly fixed by removing unnecessary references.

2014-05-29Refactoring from std::ostream to llvm::raw_ostreamMartin Nowack
According to LLVM: lightweight and simpler implementation of streams.
2014-04-24Removed ununsed Executor field in WeightedRandomSearcher to silenceDan Liew
clang warning.
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
