positional arguments:

INTERESTINGNESS_TEST

Executable to check interestingness of test cases

TEST_CASE

Test cases

options:

-h, --help

show this help message and exit

--n N, -n N

Number of cores to use; C-Vise tries to automatically pick a good setting but its choice may be too low or high for your situation

--tidy

Do not make a backup copy of each file to reduce as file.orig

--shaddap

Suppress output about non-fatal internal errors

--die-on-pass-bug

Terminate C-Vise if a pass encounters an otherwise non-fatal problem

--sllooww

Try harder to reduce, but perhaps take a long time to do so

--also-interesting EXIT_CODE

A process exit code (somewhere in the range 64-113 would be usual) that, when returned by the interestingness test, will cause C-Vise to save a copy of the variant

--debug

Print debug information (alias for --log-level=DEBUG)

--log-level {INFO,DEBUG,WARNING,ERROR}

Define the verbosity of the logged events

--log-file LOG_FILE

Log events into LOG_FILE instead of stderr. New events are appended to the end of the file

--no-give-up

Don't give up on a pass that hasn't made progress for 50000 iterations

--print-diff

Show changes made by transformations, for debugging

--save-temps

Don't delete /tmp/cvise-xxxxxx directories on termination

--skip-initial-passes

Skip initial passes (useful if input is already partially reduced)

--skip-interestingness-test-check, -s

Skip initial interestingness test check

--remove-pass REMOVE_PASS

Remove all instances of the specified passes from the schedule (comma-separated)

--start-with-pass START_WITH_PASS

Start with the specified pass

--no-timing

Do not print timestamps about reduction progress

--timestamp

Print timestamps instead of relative time from a reduction start

--timeout [TIMEOUT]

Interestingness test timeout in seconds

--no-cache

Don't cache behavior of passes

--skip-key-off

Disable skipping the rest of the current pass when 's' is pressed

--max-improvement BYTES

Largest improvement in file size from a single transformation that C-Vise should accept (useful only to slow C-Vise down)

--pass-group {opencl-120,delta,binary,all}

Set of passes used during the reduction

--pass-group-file PASS_GROUP_FILE

JSON file defining a custom pass group

--clang-delta-std {c++98,c++11,c++14,c++17,c++20,c++2b}

Specify clang_delta C++ standard, it can rapidly speed up all clang_delta passes

--clang-delta-preserve-routine CLANG_DELTA_PRESERVE_ROUTINE

Preserve the given function in replace-function-defwith-decl clang delta pass

--not-c

Don't run passes that are specific to C and C++, use this mode for reducing other languages

--renaming

Enable all renaming passes (that are disabled by default)

--list-passes

Print all available passes and exit

--version

show program's version number and exit

--commands COMMANDS, -c COMMANDS

Use bash commands instead of an interestingness test case

--to-utf8

Convert any non-UTF-8 encoded input file to UTF-8

--skip-after-n-transforms SKIP_AFTER_N_TRANSFORMS

Skip each pass after N successful transformations

available shortcuts:

S - skip execution of the current pass D - toggle --print-diff option
