            Bug ID: 68980
           Summary: [6 regression] ps -o cmd in gotest isn't portable
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: go
          Assignee: ian at airs dot com
          Reporter: ro at gcc dot gnu.org
                CC: cmang at google dot com
  Target Milestone: ---
              Host: *-*-solaris2.*
            Target: *-*-solaris2.*
             Build: *-*-solaris2.*

The use of ps -o cmd in gotest isn't portable: on Solaris, this leads to lots
of usage messages in libgo.log

PASS
ps: unknown output format: -o cmd
usage: ps [ -aAdeflcjLPyZ ] [ -o format ] [ -t termlist ]
        [ -u userlist ] [ -U userlist ] [ -G grouplist ]
        [ -p proclist ] [ -g pgrplist ] [ -s sidlist ] [ -z zonelist ]
  'format' is one or more of:
        user ruser group rgroup uid ruid gid rgid pid ppid pgid sid taskid ctid
        pri opri pcpu pmem vsz rss osz nice class time etime stime zone zoneid
        f s c lwp nlwp psr tty addr wchan fname comm args projid project pset
/vol/gcc/src/hg/trunk/local/libgo/testsuite/gotest[623]: 19046 Terminated
PASS: bufio

and sometimes, in cases where there really some process needs to be killed, to
a
hang of the whole make check.

Solaris ps offers ps -o comm instead, and I suspect there might be more
differences
on other targets.
