            Bug ID: 108151
           Summary: gcc.dg/pr64536.c stores pointers in a long, broken for
                    llp64
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite
          Assignee: unassigned at gcc dot gnu.org
          Reporter: nightstrike at gmail dot com
  Target Milestone: ---

gcc/testsuite/gcc.dg/pr64536.c contains lines such as the following:

struct S { long q; } *h;
long a, b, g, j, k, *c, *d, *e, *f, *i;
i =3D (long *) (h->q =3D *f);
*c++ =3D (long) f;

These lines were added with the following commit:
adfac8dfed7b (Jakub Jelinek 2015-01-09 22:17:10 +0100 56)

This has the erroneous assumption that a long can hold a pointer.  This sho=
uld
probably just use intptr_t or __INTPTR_TYPE__ for all occurrences.  Changin=
g q
to be an __INTPTR_TYPE__ and both casts of f to be likewise makes the test
pass.

Note: I didn't put mingw in the target field, because this affects any LLP64
platform.=
