Subject: [Bug c/24900] new "value computed is not used" warning in gcc 4.1
Date: Wed, 16 Nov 2005 18:30:00 -0000	[thread overview]
Message-ID: <20051116183024.4459.qmail@sourceware.org> (raw)
In-Reply-To: <bug-24900-4603@http.gcc.gnu.org/bugzilla/>



------- Comment #3 from pinskia at gcc dot gnu dot org  2005-11-16 18:30 -------
Here is a further reduced testcase:
unsigned long t(void);

void apic_write_atomic(unsigned long reg, unsigned int v)
{
 ((__typeof__(*((volatile unsigned int *)((t())+reg))))t());
}

-Wall is all is needed to reproduce the issue.
