            Bug ID: 79356
           Summary: XPASS in attr-alloc_size-11.c
           Product: gcc
           Version: 7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: vogt at linux dot vnet.ibm.com
                CC: krebbel at gcc dot gnu.org, msebor at gcc dot gnu.org
  Target Milestone: ---
              Host: s390x
            Target: s390x

The test has two xfails that do pass on s390x with --with-arch=zEC12 (not
tested without that):

--
/* The following tests fail because of missing range information.  */ 
TEST (signed char, SCHAR_MIN + 2, ALLOC_MAX);   /* { dg-warning "argument 1
ran\
ge \\\[13, \[0-9\]+\\\] exceeds maximum object size 12" "missing range info
for\
 signed char" { xfail *-*-* } } */ 
TEST (short, SHRT_MIN + 2, ALLOC_MAX); /* { dg-warning "argument 1 range
\\\[13\
, \[0-9\]+\\\] exceeds maximum object size 12" "missing range info for short"
{\
 xfail *-*-* } } */ 
--

The test was added in r244290:
