It starts a simple web server that acts as a simple JSON datasource for grafana
|
|
Improves querying of the .stats file, reduces its size, speeds up reads and
writes and has better defined fail behaviour.

* Added handling of --sym-arg
* Resolved the crash when minimum and maximum number of arguments for --sym-args are equal
* Replaced "range" with "n_args" produced by --sym-args
* Added model_version variable (constrained to 1), to prevent klee complaining about insufficient input
* Allow a single dash to prefix an option
* Arrange the elements in the correct order: command-line arguments, files, stdin, stdout
* Added test/Runtime/POSIX/GenRandomBout.c test, with a substitution for %gen-random-bout in test/lit.cfg
|

|
|
* remove wrapper script invocation and script
* add build instruction to test cases
* added additional checks
* add check to avoid execution of tests if KLEE is not compiled with
libc++

* switch to Python 3
* add file encoding
* some PEP8 reformatting
* fix TOCTOU for open
* replace trimZeros() with rstrip
* remove unused pos/args variables
* remove --write-ints (print by default)
* remove progname section (unused)
* added/modified output rows
- "data:" now shows the Python representation (for use in scripts)
- "hex :" shows the hex representation
- "text:" shows ASCII, all out-of-range/non-printable characters are replaced by a dot
- "int :"/"uint:" print (unsigned) 8/16/32/64 bit integers
* reduce width for object counter to needed minimum instead of 4
* refactor printing into function

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)

concrete arguments and files.
* Sample use cases:
* Using an interesting input as a seed, such as a crashing input.
* Analyzing the path condition of a crashing input.
* Also added the test: test/Runtime/POSIX/GenBout.c

Starting with llvm 5, arguments of a function are not an iterator, but
an array. So they cannot be incremented in-place. Add a local auto
variable and increment that.
Otherwise we see:
../tools/klee/main.cpp:661:23: error: expression is not assignable
Value *oldArgv = &*(++mainFn->arg_begin());

and introduce klee_open_compressed_output_file with similar behavior
along some other minor improvements
|
|
to have only solver options.
|
|
|
|
* also adds klee-replay as dependency for systemtests
|
|
LLVM 4 renamed and splitted some headers. Take this into account in
includes.

To enable the POSIX support, the former implementation instrumented the
main function and inserted a call to `klee_init_env` at the beginning.
This has multiple disadvantages:
* debugging information was not correctly propagated leaving the call to
`klee_init_env` without debug information
* the main function always required `int arg, char**` as part of the
function definition of `main`
Based on the new linking infrastructure, we can now add an additional
wrapper `__klee_posix_wraper(int, char**)` that gets always called when
POSIX support is enabled. It executes `klee_init_env` and after that
calls the `main` function.
Enabling POSIX support only requires the renaming of the user provided
`main` into `__klee_posix_wrapped_main` in addition to linking.

Replace the remaining occurrences of `Inst::Create()` with
`llvm::Builder` to manage metadata automatically and to fold
instructions.
C++11 it and clang-format

No need to flush it, see llvm-mirror/llvm@d4177b2
