[Bug debug/41893] ICE with -combine and debug

[kevin at koconnor dot net]

------- Comment #4 from kevin at koconnor dot net  2010-03-28 14:43 -------
This problem has returned.  The test case above no longer causes the problem -
but simply changing the test case to also assign a value to the variable shows
the problem.  This is with gcc from svn (r157452).

New test case:

============================================================
cat > file1.c << EOF
struct s1_s {
    int v;
};
struct s1_s g1;
void __attribute__((externally_visible)) func1() {
    struct s1_s *l1 = &g1;
    l1->v = 0;
}
EOF

cat > file2.c << EOF
extern struct s1_s g1;
void func2() {
    &g1;
}
EOF

cc -O -g -fwhole-program -combine -c file1.c file2.c
============================================================
