   -pass-remarks=<pattern>                         - Enable 
optimization remarks from passes whose name match the given 
regular expression
   -pass-remarks-analysis=<pattern>                - Enable 
optimization analysis remarks from passes whose name match the 
given regular expression
   -pass-remarks-missed=<pattern>                  - Enable missed 
optimization remarks from passes whose name match the given
