            Bug ID: 30283
           Summary: [display text] The metrics command should honor the
                    order of the visibility specifications
           Product: binutils
           Version: 2.40
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gprofng
          Assignee: vladimir.mezentsev at oracle dot com
          Reporter: ruud.vanderpas at oracle dot com
  Target Milestone: ---

The metrics command is used to specify the metrics to be shown. The visibility
part is used to select whether this should be the absolute number, and/or the
percentage, etc.

I would expect the order in the visibility specifications to be honored. For
example, ".%" shows the percentage in the second column, but "%." should show
the percentage first.

As the example below demonstrates, this order is currently ignored. This should
be changed.

$ gprofng display text -limit 5 -metrics e.%totalcpu -functions exp.er
Print limit set to 5
Current metrics: e.%totalcpu:name
Current Sort Metric: Exclusive Total CPU Time ( e.%totalcpu )
Functions sorted by metric: Exclusive Total CPU Time

Excl. Total    Name
CPU
 sec.      %
2.422 100.00   <Total>
2.302  95.04   mxv_core
0.070   2.89   init_data
0.020   0.83   erand48_r
0.010   0.41   __drand48_iterate
