            Bug ID: 79749
           Summary: Many sparc testcases FAIL at -O0 with
                    -fomit-frame-pointer
           Product: gcc
           Version: 7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ro at gcc dot gnu.org
                CC: ebotcazou at gcc dot gnu.org
  Target Milestone: ---
            Target: sparc*-*-solaris2.*

Prompted by a different report, I ran the C testsuite with -fomit-frame-pointer
and noticed that a large number of testcases FAIL with -fomit-frame-pointer
added: 95 new failures with -m32, 30 new failures with -m64.  A considerable
number fails in both cases, like gcc.c-torture/execute/20021118-1.c.

In that case (haven't tried others) the failure already exists with gcc 3.4.6.
