Add support for more of `llvm-mca` options #11

vchuravy commented 5 years ago

llvm-mca supports way more options than iaca so I should figure out a nice way to expose them.

OVERVIEW: llvm machine code performance analyzer.

USAGE: llvm-mca [options] <input file>

OPTIONS:
  -all-stats                      - Print all hardware statistics
  -all-views                      - Print all views including hardware statistics
  -dispatch=<uint>                - Override the processor dispatch width
  -dispatch-stats                 - Print dispatch statistics
  -help                           - Display available options (-help-hidden for more)
  -help-hidden                    - Display all available options
  -help-list                      - Display list of available options (-help-list-hidden for more)
  -help-list-hidden               - Display list of all available options
  -instruction-info               - Print the instruction info view (enabled by default)
  -instruction-tables             - Print instruction tables
  -iterations=<uint>              - Number of iterations to run
  -lqueue=<uint>                  - Size of the load queue (unbound by default)
  -march=<string>                 - Target arch to assemble for, see -version for available targets
  -mcpu=<cpu-name>                - Target a specific cpu type (-mcpu=help for details)
  -mtriple=<string>               - Target triple to assemble for, 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
  -print-all-options              - Print all option values after command line parsing
  -print-options                  - Print non-default options after command line parsing
  -register-file-size=<uint>      - Maximum number of physical registers which can be used for register mappings

  -resource-pressure              - Print the resource pressure view (enabled by default)
  -retire-stats                   - Print retire control unit statistics
  -scheduler-stats                - Print scheduler statistics
  -squeue=<uint>                  - Size of the store queue (unbound by default)
  -summary-view                   - Print summary view (enabled by default)
  -timeline                       - Print the timeline view
  -timeline-max-cycles=<uint>     - Maximum number of cycles in the timeline view. Defaults to 80 cycles
