            Bug ID: 71934
           Summary: pch cannot be disabled so gcc cannot be position
                    independent
           Product: gcc
           Version: 7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: pch
          Assignee: unassigned at gcc dot gnu.org
          Reporter: nsz at gcc dot gnu.org
  Target Milestone: ---

gcc should be possible to build as PIE by disabling PCH.
(e.g. for running gcc natively on an fdpic target)

some users might not care about PCH, but want PIE gcc,
making PCH position independent can make it slower,
but optionally disabling it should be non-controversial.
