OPTIONS:

Generic Options:

  --help                           - Display available options (--help-hidden for more)

  --version                        - Display the version of this program

Tool Options:

  --dispatch=<uint>                - Override the processor dispatch width
  --instruction-tables             - Print instruction tables
  --iterations=<uint>              - Number of iterations to run
  --json                           - Print the output in json format
  --lqueue=<uint>                  - Size of the load queue
  --march=<string>                 - Target architecture. See -version for available targets
  --mattr=<a1,+a2,-a3,...>         - Target specific attributes (-mattr=help for details)

  --mtriple=<string>               - Target triple. See -version for available targets
  --noalias                        - If set, assume that loads and stores do not alias
  -o <filename>                    - Output filename
  --output-asm-variant=<int>       - Syntax variant to use for output printing
