OVERVIEW: LLVM automatic testcase reducer.

USAGE: llvm-reduce [options] <input llvm ll/bc file>

OPTIONS:

Color Options:

  --color                             - Use colors in output (default=autodetect)

Generic Options:

  --help                              - Display available options (--help-hidden for more)
  --help-list                         - Display list of available options (--help-list-hidden for more)
  --version                           - Display the version of this program

llvm-reduce options:

  --abort-on-invalid-reduction        - Abort if any reduction results in invalid IR
  --delta-passes=<string>             - Delta passes to run, separated by commas. By default, run all delta passes.
  --in-place                          - WARNING: This option will replace your input file with the reduced version!
  --ir-passes=<string>                - A textual description of the pass pipeline, same as what's passed to `opt -passes`.
  -j <uint>                           - Maximum number of threads to use to process chunks. Set to 1 to disable parallelism.
  --max-pass-iterations=<int>         - Maximum number of times to run the full set of delta passes (default=5)
  --mtriple=<string>                  - Set the target triple
  --preserve-debug-environment        - Don't disable features used for crash debugging (crash reports, llvm-symbolizer and core dumps)
  --print-delta-passes                - Print list of delta passes, passable to --delta-passes as a comma separated list
  --skip-delta-passes=<string>        - Delta passes to not run, separated by commas. By default, run all delta passes.
  --starting-granularity-level=<uint> - Number of times to divide chunks prior to first test
  --test=<string>                     - Name of the interesting-ness test to be run
  --test-arg=<string>                 - Arguments passed onto the interesting-ness test
  --verbose                           - Print extra debugging information
  --write-tmp-files-as-bitcode        - Always write temporary files as bitcode instead of textual IR
  -x=<value>                          - Input language ('ir' or 'mir')

    =mir
