NAME

       mlprof - display profiling information for a MLton-compiled executable

SYNOPSIS

       mlprof [option ...] a.out [mlmon.out ...]

DESCRIPTION

       mlprof  extracts  information  from an executable compiled by MLton with -profile alloc or
       -profile time and the resulting mlmon.out file produced by running the executable.

       The output of mlprof consists of an initial line indicating the total amount of  CPU  time
       or  bytes allocated.  After this, source functions are listed along with the percentage of
       this total that they used,  in  decreasing  order.   If  the  program  was  compiled  with
       -profile-stack  true,  mlprof  will  display  the  time spent or bytes allocated while the
       function was on the stack and in GC in addition to the time or bytes that the function  is
       directly responsible for.

       With multiple mlmon.out files, mlprof will sum the profiling information.

OPTIONS

       -call-graph file
              Write  a  call  graph  containing the table data to a dot file.  See the MLton User
              Guide for details.

       -graph-title string
              Set the call-graph title.

       -gray {false|true}
              Gray call-graph nodes  according  to  stack  %.   This  only  makes  sense  if  the
              executable was compiled -profile-stack true.

       -keep exp
              Only  show functions specified by exp.  For details on the allowed expressions, see
              the MLton User Guide.  Multiple -keep expressions are not allowed.

       -mlmon file
              Process the list of whitespace-separated mlmon.out files  found  in  the  specified
              file.

       -raw {false|true}
              Show the raw counts in addition to the percentages.

       -show-line {false|true}
              Show the file and line for each function.

       -split regexp
              Treat duplicates of functions whose name matches regexp as different functions.

       -thresh x
              An  abbreviation  for  -keep  '(thresh  x)',  which  only  prints information about
              functions whose percentage is greater than or equal to x, where 0 <= x <= 100.0.

       -tolerant {false|true}
              Print a warning about broken mlmon.out files, but do not exit.
