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).

2019-10-29ExecutorTimers: refactor and move to support libFrank Busse
- moves timer handling from Executor into support lib - introduces TimerGroup, removes TimerInfo/WriteStatsTimer/UpdateReachableTimer/WriteIStatsTimer classes - removes ExecutorTimers.cpp and ExecutorTimerInfo.h - removes -max-instruction-time flag (see #1114)
2019-09-03Moved solver-related header files into a separate klee/Solver/ directory.Cristian Cadar
2019-07-30Use #include "klee/..." (instead of #include <klee/...>) consistently.Cristian Cadar
2019-07-30Consolidated Expr-related include files into a single include/klee/Expr ↵Cristian Cadar
directory. This improves the organization of the code, and also makes it easier to reuse Expr outside KLEE.

libutil.h header there.

2019-03-05workaround for LLVM PR39177Julian Büning
provides a workaround for LLVM bug PR39177, which affects LLVM versions 3.9 - 7.0.0: https://bugs.llvm.org/show_bug.cgi?id=39177 This commit is intended to be reverted once support for LLVM versions <= 7 is dropped from KLEE.
2018-11-02Introduced a constraint solving option category to which all the options in ↵Cristian Cadar
CmdLineOptions.cpp are currently added.
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)
2018-10-26llvm6: SetVersionPrinter now passes down a streamJiri Slaby
I.e. klee::printVersion should now have a parameter -- the output stream. Change both the prototype and the implementation to handle this properly. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
2018-10-26llvm5: handle getOrInsertFunction terminatorJiri Slaby
llvm 5 does not terminate getOrInsertFunction parameters with NULL, take care of that. Since commit 9d54400bba7eb04bca80fce97fa170452d19eaf1. Signed-off-by: Jiri Slaby <jirislaby@gmail.com>
