Subject: [Bug middle-end/21474] missed optimizations when comparing address to NULL
Date: Thu, 15 Nov 2007 17:03:00 -0000 [thread overview]
Message-ID: <20071115170331.21184.qmail@sourceware.org> (raw)

------- Comment #3 from manu at gcc dot gnu dot org 2007-11-15 17:03 -------
I think it is odd that if you call subr(i,0), it doesn't crash, that is &(p->a)
does not actually dereferences p. Nonetheless, I agree that the behaviour seems
inconsistent. A nice little project for someone. As they say, patches welcome!
