Tips

Get Stack Pointer

Use this macro [1]: 

#define current_stack_pointer ({ \
        register unsigned long esp asm("esp"); \
        asm("" : "=r"(esp)); \
        esp; \
        })

Turn errors into warning

From the manual 

-Wno-error=foo Turn warning “foo” into an warning even if -Werror is specified.
