afl-4.21c-bp156.2.3.1

- updated to 4.21c
  * afl-fuzz
  - fixed a regression in afl-fuzz that resulted in a 5-10% performace loss
    do a switch from gettimeofday() to clock_gettime() which should be rather
    three times faster. The reason for this is unknown.
  - new queue selection algorithm based on 2 core years of queue data
    analysis. gives a noticable improvement on coverage although the results
    seem counterintuitive :-)
  - added AFL_DISABLE_REDUNDANT for huge queues
  - added `AFL_NO_SYNC` environment variable that does what you think it does
  - fix AFL_PERSISTENT_RECORD
  - run custom_post_process after standard trimming
  - prevent filenames in the queue that have spaces
  - minor fix for FAST schedules
  - more frequent stats update when syncing (todo: check performance impact)
  - now timing of calibration, trimming and syncing is measured seperately,
    thanks to @eqv!
  - -V timing is now accurately the fuzz time (without syncing), before
    long calibration times and syncing could result in now fuzzing being
    made when the time was already run out until then, thanks to @eqv!
  - fix -n uninstrumented mode when ending fuzzing
  - enhanced the ASAN configuration
  - make afl-fuzz use less memory with cmplog and fix a memleak
  * afl-cc:
  - re-enable i386 support that was accidently disabled
  - fixes for LTO and outdated afl-gcc mode for i386
  - fix COMPCOV split compare for old LLVMs
  - disable xml/curl/g_ string transform functions because we do not check
    for null pointers ... TODO
  - ensure shared memory variables are visible in weird build setups
  - compatability to new LLVM 19 changes
  * afl-cmin
  - work with input files that have a space
  * afl-showmap
  - fix memory leak on shmem testcase usage (thanks to @ndrewh)
  - minor fix to collect coverage -C (thanks to @bet4it)
  * Fixed a shmem mmap bug (that rarely came up on MacOS)
  * libtokencap: script generate_libtoken_dict.sh added by @a-shvedov

- updated to 4.20c
  + A new forkserver communication model is now introduced. afl-fuzz is
    backward compatible to old compiled targets if they are not built
    for CMPLOG/Redqueen, but new compiled targets will not work with
    old afl-fuzz versions!
  + Recompile all targets that are instrumented for CMPLOG/Redqueen!
  - AFL++ now supports up to 4 billion coverage edges, up from 6 million.
  - New compile option: `make PERFORMANCE=1` - this will enable special
    CPU dependent optimizations that make everything more performant - but
    the binaries will likely won't work on different platforms. Also
    enables a faster hasher if the CPU requirements are met.
  - The persistent record feature (see config.h) was expanded to also
    support replay, thanks to @quarta-qti !
  - afl-fuzz:
  - the new deterministic fuzzing feature is now activated by default,
    deactivate with -z. Parameters -d and -D are ignored.
  - small improvements to CMPLOG/redqueen
  - workround for a bug with MOpt -L when used with -M - in the future
    we will either remove or rewrite MOpt.
  - fix for `-t xxx+` feature
  - -e extension option now saves the queue items, crashes, etc. with the
    extension too
  - fixes for trimmming, correct -V time and reading stats on resume by eqv
    thanks a lot!
  - afl-cc:
  - added collision free caller instrumentation to LTO mode. activate with
    `AFL_LLVM_LTO_CALLER=1`. You can set a max depth to go through single
    block functions with `AFL_LLVM_LTO_CALLER_DEPTH` (default 0)

  - fix for GCC_PLUGIN cmplog that broke on std::strings
  - afl-whatsup:
  - now also displays current average speed

  - afl-fuzz:
  - default power schedule is now EXPLORE, due a fix in fast schedules
    explore is slightly better now.
  - fixed minor issues in the mutation engine, thanks to @futhewo for
    reporting!
  - better deterministic fuzzing is now available, benchmarks have shown
    to improve fuzzing. Enable with -D. Thanks to @kdsjZh for the PR!
  - afl-cc:
  - large rewrite by @SonicStark which fixes a few corner cases, thanks!
  - LTO mode now requires llvm 12+

    `instrumentation/README.injections.md` how to activate/use/expand.
  - compcov/LAF-intel:
  - floating point splitting bug fix by @hexcoder
  - due a bug in LLVM 17 integer splitting is disabled there!
  - when splitting floats was selected, integers were always split as well,
    fixed to require AFL_LLVM_LAF_SPLIT_COMPARES or _ALL as it should
  - dynamic instrumentation filtering for LLVM NATIVE, thanks @Mozilla!
    see utils/dynamic_covfilter/README.md
  - qemu_mode:
  - plugins are now activated by default and a new module is included that

    speed is in comparison to other setups.

- updated to 4.08c
  - afl-fuzz:
  - new mutation engine: mutations that favor discovery more paths are
    prefered until no new finds for 10 minutes then switching to mutations
    that favor triggering crashes. Modes and switch time can be configured
    with `-P`. Also input mode for the target can be defined with `-a` to
    be `text` or `binary` (defaults to `generic`)
  - new custom mutator that has the new afl++ engine (so it can easily
    incorporated into new custom mutators), and also comes with a standalone
    command line tool! See custom_mutators/aflpp/standalone/
  - display the state of the fuzzing run in the UI :-)
  - fix timeout setting if '+' is used or a session is restarted
  - -l X option to enable base64 transformation solving

    fuzz inputs
  - you can set the time for syncing to other fuzzer now with
    AFL_SYNC_TIME

  - better auto detection of map size
  - fix sanitizer settings (bug since 3.10c)
  - fix an off-by-one overwrite in cmplog
  - add non-unicode variants from unicode-looking dictionary entries
  - Rust custom mutator API improvements
  - Imported crash stats painted yellow on resume (only new ones are red)
  - afl-cc:
  - added AFL_NOOPT that will just pass everything to the normal
    gcc/clang compiler without any changes - to pass weird configure
    scripts
  - fixed a crash that can occur with ASAN + CMPLOG together plus
    better support for unicode (thanks to @stbergmann for reporting!)
  - fixed a crash in LAF transform for empty strings
  - handle erroneous setups in which multiple afl-compiler-rt are
    compiled into the target. This now also supports dlopen()
    instrumented libs loaded before the forkserver and even after the
    forkserver is started (then with collisions though)
  - the compiler rt was added also in object building (-c) which
    should have been fixed years ago but somewhere got lost :(
  - Renamed CTX to CALLER, added correct/real CTX implementation to
    CLASSIC
  - qemu_mode:
  - added AFL_QEMU_EXCLUDE_RANGES env by @realmadsci, thanks!
  - if no new/updated checkout is wanted, build with:
    NO_CHECKOUT=1 ./build_qemu_support.sh
  - we no longer perform a "git drop"
  - afl-cmin: support filenames with spaces
- afl-3.0c-fix-paths.patch: refreshed

- update to 3.10c
  - Mac OS ARM64 support
  - Android support fixed and updated by Joey Jiaojg - thanks!
  - New selective instrumentation option with __AFL_COVERAGE_* commands
    to be placed in the source code.
    Check out instrumentation/README.instrument_list.md
  - afl-fuzz
  - Making AFL_MAP_SIZE (mostly) obsolete - afl-fuzz now learns on
    start the target map size
  - upgraded cmplog/redqueen: solving for floating point, solving
    transformations (e.g. toupper, tolower, to/from hex, xor,
    arithmetics, etc.). This is costly hence new command line option
    `-l` that sets the intensity (values 1 to 3). Recommended is 2.
  - added `AFL_CMPLOG_ONLY_NEW` to not use cmplog on initial seeds
    from `-i` or resumes (these have most likely already been done)
  - fix crash for very, very fast targets+systems (thanks to mhlakhani
    for reporting)
  - on restarts (`-i`)/autoresume (AFL_AUTORESUME) the stats are now
    reloaded and used, thanks to Vimal Joseph for this patch!
  - changed the meaning of '+' of the '-t' option, it now means to
    auto-calculate the timeout with the value given being the max
    timeout. The original meaning of skipping timeouts instead of
    abort is now inherent to the -t option.
  - if deterministic mode is active (`-D`, or `-M` without `-d`) then
    we sync after every queue entry as this can take very long time
    otherwise
  - added minimum SYNC_TIME to include/config.h (30 minutes default)
  - better detection if a target needs a large shared map
  - fix for `-Z`
  - fixed a few crashes

  - cmplog/redqueen can now process basic libc++ and libstdc++
    std::string comparisons (no position or length type variants)
  - added support for __afl_coverage_interesting() for LTO and our
    own PCGUARD (llvm 10.0.1+), read more about this function and
    selective coverage in instrumentation/README.instrument_list.md
  - added AFL_LLVM_INSTRUMENT option NATIVE for native clang pc-guard
    support (less performant than our own), GCC for old afl-gcc and
    CLANG for old afl-clang
  - fixed a potential crash in the LAF feature
  - workaround for llvm bitcast lto bug
  - workaround for llvm 13

  - afl-fuzz
  - not specifying -M or -S will now auto-set "-S default"
  - deterministic fuzzing is now disabled by default and can be enabled with
  - D. It is still enabled by default for -M.
  - a new seed selection was implemented that uses weighted randoms based on
    a schedule performance score, which is much better that the previous
    walk the whole queue approach. Select the old mode with -Z (auto enabled
    with -M)
  - Marcel Boehme submitted a patch that improves all AFFast schedules :)
  - the default schedule is now FAST
  - memory limits are now disabled by default, set them with -m if required

  - loaded extras now have a duplication protection
  - If test cases are too large we do a partial read on the maximum
    supported size
  - longer seeds with the same trace information will now be ignored
    for fuzzing but still be used for splicing
  - crashing seeds are now not prohibiting a run anymore but are
    skipped - they are used for splicing, though
  - update MOpt for expanded havoc modes
  - setting the env var AFL_NO_AUTODICT will not load an LTO autodictionary
  - added NO_SPLICING compile option and makefile define

  - somewhere we broke -n dumb fuzzing, fixed
  - added afl_custom_describe to the custom mutator API to allow for easy
    mutation reproduction on crashing inputs
  - instrumentation
  - We received an enhanced gcc_plugin module from AdaCore, thank you
    very much!!
  - not overriding -Ox or -fno-unroll-loops anymore
  - we now have our own trace-pc-guard implementation. It is the same as
  - fsanitize-coverage=trace-pc-guard from llvm 12, but: it is a) inline
    and b) works from llvm 10.0.1 + onwards :)
  - new llvm pass: dict2file via AFL_LLVM_DICT2FILE, create afl-fuzz
  - x dictionary of string comparisons found during compilation
  - LTO autodict now also collects interesting cmp comparisons,
    std::string compare + find + ==, bcmp

    https://github.com/AFLplusplus/Grammar-Mutator
  - a few QOL changes for Apple and its outdated gmake
  - afl-fuzz:
  - fix for auto dictionary entries found during fuzzing to not throw out
    a -x dictionary
  - added total execs done to plot file
  - AFL_MAX_DET_EXTRAS env variable added to control the amount of
    deterministic dict entries without recompiling.
  - AFL_FORKSRV_INIT_TMOUT env variable added to control the time to wait
    for the forkserver to come up without the need to increase the overall
    timeout.

  - Due to the instrumentation needing more memory, the initial memory sizes
    for -m have been increased
  - afl-fuzz:
  - added -F option to allow -M main fuzzers to sync to foreign fuzzers,
    e.g. honggfuzz or libfuzzer
  - added -b option to bind to a specific CPU
  - eliminated CPU affinity race condition for -S/-M runs
  - expanded havoc mode added, on no cycle finds add extra splicing and
    MOpt into the mix

  - support for AFL_LLVM_ALLOWLIST/AFL_LLVM_DENYLIST (previous
    AFL_LLVM_WHITELIST and AFL_LLVM_INSTRUMENT_FILE are deprecated and
    are matched to AFL_LLVM_ALLOWLIST). The format is compatible to llvm
    sancov, and also supports function matching :)
  - added neverzero counting to trace-pc/pcgard
  - fixes for laf-intel float splitting (thanks to mark-griffin for
    reporting)
  - fixes for llvm 4.0
  - skipping ctors and ifuncs for instrumentation
  - LTO: switch default to the dynamic memory map, set AFL_LLVM_MAP_ADDR
    for a fixed map address (eg. 0x10000)
  - LTO: improved stability for persistent mode, no other instrumentation
    has that advantage
  - LTO: fixed autodict for long strings
  - LTO: laf-intel and redqueen/cmplog are now applied at link time
    to prevent llvm optimizing away the splits
  - LTO: autodictionary mode is a fixed default now

- updated to 2.66c
  - renamed blacklist/whitelist to ignorelist/instrumentlist ->
    AFL_LLVM_INSTRUMENT_FILE and AFL_GCC_INSTRUMENT_FILE
  - warn on deprecated environment variables
  - afl-fuzz:
  - -S secondary nodes now only sync from the main node to increase
    performance, the -M main node still syncs from everyone. Added checks
    that ensure exactly one main node is present and warn otherwise
  - Add -D after -S to force a secondary to perform deterministic fuzzing
  - If no main node is present at a sync one secondary node automatically
    becomes a temporary main node until a real main nodes shows up

  - Ensure that the targets are killed on exit
  - fix/update to MOpt (thanks to arnow117)
  - added MOpt dictionary support from repo
  - added experimental SEEK power schedule. It is EXPLORE with ignoring
    the runtime and less focus on the length of the test case
  - llvm_mode:
  - the default instrumentation is now PCGUARD if the llvm version is >= 7,
    as it is faster and provides better coverage. The original afl
    instrumentation can be set via AFL_LLVM_INSTRUMENT=AFL. This is
    automatically done when the instrument_file list feature is used.
  - PCGUARD mode is now even better because we made it collision free - plus
    it has a fixed map size, so it is also faster! :)
  - some targets want a ld variant for LD that is not gcc/clang but ld,
    added afl-ld-lto to solve this
  - lowered minimum required llvm version to 3.4 (except LLVMInsTrim, which
    needs 3.8.0)
  - instrument_file list feature now supports wildcards (thanks to sirmc)

    compiled by default anymore.
  - allow running in /tmp (only unsafe with umask 0)
  - persistent mode shared memory testcase handover (instead of via
    files/stdin) - 10-100% performance increase

  - added former post_library examples to examples/custom_mutators/
  - Dockerfile upgraded to Ubuntu 20.04 Focal and installing llvm 11 and
    gcc 10 so afl-clang-lto can be build

- updated to 2.65c
  - afl-fuzz:
  - AFL_MAP_SIZE was not working correctly
  - better python detection
  - an old, old bug in afl that would show negative stability in rare
    circumstances is now hopefully fixed
  - AFL_POST_LIBRARY was deprecated, use AFL_CUSTOM_MUTATOR_LIBRARY
    instead (see docs/custom_mutators.md)
  - llvm_mode:
  - afl-clang-fast/lto now do not skip single block functions. This
    behaviour can be reactivated with AFL_LLVM_SKIPSINGLEBLOCK
  - if LLVM 11 is installed the posix shm_open+mmap is used and a fixed
    address for the shared memory map is used as this increases the
    fuzzing speed
  - InsTrim now has an LTO version! :-) That is the best and fastest mode!
  - fixes to LTO mode if instrumented edges > MAP_SIZE
  - CTX and NGRAM can now be used together
  - CTX and NGRAM are now also supported in CFG/INSTRIM mode
  - AFL_LLVM_LAF_TRANSFORM_COMPARES could crash, fixed
  - added AFL_LLVM_SKIP_NEVERZERO to skip the never zero coverage counter
    implementation. For targets with few or no loops or heavily called
    functions. Gives a small performance boost.
  - qemu_mode:
  - add information on PIE/PIC load addresses for 32 bit
  - better dependency checks
  - gcc_plugin:
  - better dependency checks
  - unicorn_mode:
  - validate_crash_callback can now count non-crashing inputs as crash as well
  - better submodule handling
  - afl-showmap: fix for -Q mode
  - added examples/afl_network_proxy which allows to fuzz a target over the
    network (not fuzzing tcp/ip services but running afl-fuzz on one system
    and the target being on an embedded device)
  - added examples/afl_untracer which does a binary-only fuzzing with the
    modifications done in memory (intel32/64 and aarch64 support)
  - added examples/afl_proxy which can be easily used to fuzz and instrument
    non-standard things
  - all:
  - forkserver communication now also used for error reporting
  - fix 32 bit build options
  - make clean now leaves qemu-3.1.1.tar.xz and the unicornafl directory
    intact if in a git/svn checkout - unless "deepclean" is used

    Additionally, this allows to run dictionaries, radamsa and cmplog.
  - fix for cmplog/redqueen mode if stdin was used
  - fix for writing a better plot_data file
  - qemu_mode: fix for persistent mode (which would not terminate or get stuck)
  - compare-transform/AFL_LLVM_LAF_TRANSFORM_COMPARES now transforms also
    static global and local variable comparisons (cannot find all though)
  - extended forkserver: map_size and more information is communicated to
    afl-fuzz (and afl-fuzz acts accordingly)
  - new environment variable: AFL_MAP_SIZE to specify the size of the shared map
  - if AFL_CC/AFL_CXX is set but empty afl compilers did fail, fixed
    (this bug is in vanilla afl too)
  - added NO_PYTHON flag to disable python support when building afl-fuzz
  - more refactoring

- updated to 2.63c
  - all:
  - big code changes to make afl-fuzz thread-safe so afl-fuzz can spawn
    multiple fuzzing threads in the future or even become a library
  - afl basic tools now report on the environment variables picked up
  - more tools get environment variable usage info in the help output
  - force all output to stdout (some OK/SAY/WARN messages were sent to
    stdout, some to stderr)
  - uninstrumented mode uses an internal forkserver ("fauxserver")
  - now builds with `-D_FORTIFY_SOURCE=2`
  - drastically reduced number of (de)allocations during fuzzing
  - afl-fuzz:
  - python mutator modules and custom mutator modules now use the same
    interface and hence the API changed
  - AFL_AUTORESUME will resume execution without the need to specify `-i -`
  - added experimental power schedules (-p):
  - mmopt: ignores runtime of queue entries, gives higher weighting to
    the last 5 queue entries
  - rare: puts focus on queue entries that hits rare branches, also ignores
    runtime
  - llvm_mode:
  - added SNAPSHOT feature (using https://github.com/AFLplusplus/AFL-Snapshot-LKM)
  - added Control Flow Integrity sanitizer (AFL_USE_CFISAN)
  - added AFL_LLVM_INSTRUMENT option to control the instrumentation type
    easier: DEFAULT, CFG (INSTRIM), LTO, CTX, NGRAM-x (x=2-16)
  - made USE_TRACE_PC compile obsolete
  - LTO collision free instrumented added in llvm_mode with afl-clang-lto -
    note that this mode is amazing, but quite some targets won't compile
  - Added llvm_mode NGRAM prev_loc coverage by Adrean Herrera
    (https://github.com/adrianherrera/afl-ngram-pass/), activate by setting
    AFL_LLVM_INSTRUMENT=NGRAM-<value> or AFL_LLVM_NGRAM_SIZE=<value>
  - Added llvm_mode context sensitive branch coverage, activated by setting
    AFL_LLVM_INSTRUMENT=CTX or AFL_LLVM_CTX=1
  - llvm_mode InsTrim mode:
  - removed workaround for bug where paths were not instrumented and
    imported fix by author
  - made skipping 1 block functions an option and is disabled by default,
    set AFL_LLVM_INSTRIM_SKIPSINGLEBLOCK=1 to re-enable this
  - qemu_mode:
  - qemu_mode now uses solely the internal capstone version to fix builds
    on modern Linux distributions
  - QEMU now logs routine arguments for CmpLog when the target is x86

  - Redqueen input-2-state mutator (cmp instructions only ATM)
  - all Python 2+3 versions supported now
  - changed execs_per_sec in fuzzer_stats from "current" execs per second
    (which is pointless) to total execs per second
  - bugfix for dictionary insert stage count (fix via Google repo PR)
  - added warning if -M is used together with custom mutators with _ONLY option
  - AFL_TMPDIR checks are now later and better explained if they fail
  - llvm_mode
  - InsTrim: three bug fixes:
    1. (minor) no pointless instrumentation of 1 block functions

    should be
    3. (major) incorrect prev_loc was written, fixed!
  - afl-clang-fast:
  - show in the help output for which llvm version it was compiled for
  - now does not need to be recompiled between trace-pc and pass

  - Added dates for releases (retroactively for all of 2017).
- Version 2.48b
  - Added AFL_ALLOW_TMP to permit some scripts to run in /tmp.
  - Fixed cwd handling in afl-analyze (similar to the quirk in afl-tmin).
  - Made it possible to point -o and -f to the same file in afl-tmin.
- Version 2.47b
  - Fixed cwd handling in afl-tmin. Spotted by Jakub Wilk.
- Version 2.46b
  - libdislocator now supports AFL_LD_NO_CALLOC_OVER for folks who do not
    want to abort on calloc() overflows.
  - Made a minor fix to libtokencap. Reported by Daniel Stender.
  - Added a small JSON dictionary, inspired on a dictionary done by Jakub Wilk.

    with -S / -d. See the discussion of FidgetyAFL in:
    https://groups.google.com/forum/#!topic/afl-users/fOPeb62FZUg
    While this does not implement the approach proposed by the authors of
    the CCS paper, the solution is a result of digging into that research;
    more improvements may follow as I do more experiments and get more
    definitive data.
- Version 2.30b:
  - Made minor improvements to persistent mode to avoid the remote
    possibility of "no instrumentation detected" issues with very low
    instrumentation densities.
  - Fixed a minor glitch with a leftover process in persistent mode.
    Reported by Jakub Wilk and Daniel Stender.
  - Made persistent mode bitmaps a bit more consistent and adjusted the way
    this is shown in the UI, especially in persistent mode.
- Version 2.29b:
  - Made a minor #include fix to llvm_mode. Suggested by Jonathan Metzman.
  - Made cosmetic updates to the docs.
- Version 2.28b:
  - Added "life pro tips" to docs/.
  - Moved testcases/_extras/ to dictionaries/ for visibility.
  - Made minor improvements to install scripts.
  - Added an important safety tip.
- Version 2.27b:
  - Added libtokencap, a simple feature to intercept strcmp / memcmp and
    generate dictionary entries that can help extend coverage.
  - Moved libdislocator to its own dir, added README.
  - The demo in experimental/instrumented_cmp is no more.
- Version 2.26b:
  - Made a fix for libdislocator.so to compile on MacOS X.
  - Added support for DYLD_INSERT_LIBRARIES.
  - Renamed AFL_LD_PRELOAD to AFL_PRELOAD.
- Version 2.25b:
  - Made some cosmetic updates to libdislocator.so, renamed one env
    variable.
- Version 2.24b:
  - Added libdislocator.so, an experimental, abusive allocator. Try
    it out with AFL_LD_PRELOAD=/path/to/libdislocator.so when running
    afl-fuzz.
- Version 2.23b:
  - Improved the stability metric for persistent mode binaries. Problem
    spotted by Kurt Roeckx.
  - Made a related improvement that may bring the metric to 100% for those
    targets.
- Version 2.22b:
  - Mentioned the potential conflicts between MSAN / ASAN and FORTIFY_SOURCE.
    There is no automated check for this, since some distros may implicitly
    set FORTIFY_SOURCE outside of the compiler's argv[].
  - Populated the support for AFL_LD_PRELOAD to all companion tools.
  - Made a change to the handling of ./afl-clang-fast -v. Spotted by
    Jan Kneschke.

  * Minor UI fixes
- includes changes from 2.20b:
  * Revamp handling of variable paths
  * Stablility improvements
  * Include current input bitmap density in UI
  * Add experimental support for parallelizing -M.
- includes changes from 2.19b:
  * Ensure auto CPU binding happens at non-overlapping times
- includes changes from 2.18b
  * Performance improvements

- afl 2.17b:
  * Remove error-prone and manual -Z option
  * automatically bind to the first free core

- afl 2.14b:
  - Added FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION as a macro
    defined when compiling with afl-gcc and friends
  - Refreshed some of the non-x86 docs.

- afl 2.13b:
  * Fixed a spurious build test error with trace-pc and
    llvm_mode/Makefile.
  * Fixed a cosmetic issue with afl-whatsup
- includes changes from 2.12b
  * Fixed a minor issue in afl-tmin that can make alphabet
    minimization less efficient during passes > 1

- afl 2.11b:
  - Fixed a minor typo in instrumented_cmp
  - Added a missing size check for deterministic insertion steps.
  - Made an improvement to afl-gotcpu when -Z not used.

  * Made several documentation updates.
  * Added some visual indicators to promote and simplify the use
    of -Z.

    Inspired by a request from Christian Holler.
  * Added a new benchmarking option, as requested by Kostya
    Serebryany.
- Changes for 2.07b
  * Added CPU affinity option (-Z) on Linux. With some caution,
    this can offer a significant (10%+) performance bump and
    reduce jitter. Proposed by Austin Seipp.
  * Updated afl-gotcpu to use CPU affinity where supported.
  * Fixed confusing CPU_TARGET error messages with QEMU build.
    Spotted by Daniel Komaromy and others.
- Changes for 2.06b
  * Worked around LLVM persistent mode hiccups with -shared code.
    Contributed by Christian Holler.
  * Added __AFL_COMPILER as a convenient way to detect that
    something is built under afl-gcc / afl-clang / afl-clang-fast
    and enable custom optimizations in your code. Suggested by
    Pedro Corte-Real.
  * Upstreamed several minor changes developed by Franjo Ivancic to
    allow AFL to be built as a library. This is fairly use-specific
    and may have relatively little appeal to general audiences.

- afl 2.05b:
  * Put __sanitizer_cov_module_init & co behind #ifdef to avoid
    problems with ASAN.
