.B \-fmax-warnings=COUNT
Set the maximum number of displayed warnings to COUNT, which should be
a numerical value or 'unlimited'.
Currently, the maximum number of displayed errors is 100. This is nice to not be flooded with error messages when things are really broken but in some situation, for example testing, it is desirable to have all error messages. So, teach sparse about '-fmax-errors=COUNT'.
