            Bug ID: 64145
           Summary: gcc.dg/graphite/isl-codegen-loop-dumping.c UNRESOLVED
                    with isl 0.14
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: other
          Assignee: unassigned at gcc dot gnu.org
          Reporter: howarth at bromo dot med.uc.edu

The gcc.dg/graphite/isl-codegen-loop-dumping.c testcase appears as UNRESOLVED
when gcc trunk is built against isl 0.14. The test suite log shows...

with -fdump-tree-graphite-all apparently not creating any dump files.

--- Comment #2 from howarth at bromo dot med.uc.edu ---
Noticing that this bug seems similar to that fixed in
https://gcc.gnu.org/ml/gcc-patches/2011-07/msg00450.html, I puzzled out that
the following change allows the gcc.dg/graphite/isl-codegen-loop-dumping.c test
case to generate the expected dump file and pass.

--- Comment #3 from howarth at bromo dot med.uc.edu ---
Also, if -fdump-tree-graphite-all alone is supposed to trigger graphite usage,
what exact level graphite optimization is to be expected (as we currently don't
enable any graphite features at -O2)?

--- Comment #4 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
AFAICT this has nothing to do with isl 0.14, but is due to a typo in r217315
where " -fgraphite-identity -fgraphite-code-generator=isl" has been deleted
instead of only " -fgraphite-code-generator=isl".
