            Bug ID: 79637
           Summary: missing documentation for PARAM_MAX_FSM_THREAD_LENGTH
           Product: gcc
           Version: 7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: driver
          Assignee: unassigned at gcc dot gnu.org
          Reporter: roland.illig at gmx dot de
  Target Milestone: ---

As a translator, I don't understand the technical babble in params.def for
PARAM_MAX_FSM_THREAD_LENGTH. Therefore I look it up in invoke.texi, which is
supposed to provide useful, understandable documentation.

In this case, invoke.texi verbatimly repeats the one-line description from
params.def, which is in no way helpful. There should be at least one paragraph
explaining what a jump thread path is.

As a general rule, the documentation in invoke.texi should not merely repeat
what is already written in params.def.
