            Bug ID: 65222
           Summary: [5 Regression] -mtune= or -march=: Not all options not
                    documented: slm, knl, shanghai, istanbul
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Keywords: documentation
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: burnus at gcc dot gnu.org

At least the following options for -mtune= or -march= are not documented:

slm, knl, shanghai, istanbul

Marked as regression as "knl" is new since GCC 5. "slm" should be simple as it
is an alias of "silvermont" (new since GCC 4.9). "shanghai" and "istanbul" seem
to exist since GCC 4.8.
