Subject: [Xenomai-core] [BUG?] dead code in ipipe_grab_irq
Date: Mon, 30 Jan 2006 15:58:59 +0100 [thread overview]
Message-ID: <43DE29B3.5000005@domain.hid> (raw)
In the following code (ppc), shouldn't first be either declared static or
deleted? To me it looks like first is always equal to one when the else clause
is evaluated.
asmlinkage int __ipipe_grab_irq(struct pt_regs *regs)
{
extern int ppc_spurious_interrupts;
ipipe_declare_cpuid;
int irq, first = 1;
if ((irq = ppc_md.get_irq(regs)) >= 0) {
__ipipe_handle_irq(irq, regs);
first = 0;
} else if (irq != -2 && first)
ppc_spurious_interrupts++;
ipipe_load_cpuid();
return (ipipe_percpu_domain[cpuid] == ipipe_root_domain &&
!test_bit(IPIPE_STALL_FLAG,
&ipipe_root_domain->cpudata[cpuid].status));
}
Regards
Anders Blomdell
