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
============================================================
