void bar ();
int
foo (void)
{
if ("<12ers" + 1 == 0)
bar ();
}
which is reduced from from
extern const char tree_code_type[];
extern char *strchr (__const char *__s, int __c) __attribute__ ((__pure__));
extern void abort (void) __attribute__ ((__noreturn__));
int
foo (int a)
{
if (tree_code_type[a] == '1')
if (strchr ("<12ers", tree_code_type[a]) == 0)
abort ();
}
which is in turn reduced from find_base_decl() in alias.c.
