Subject: i386 and x86-64 bitops function prototypes differ
Date: Fri, 26 Jan 2007 06:35:55 -0800	[thread overview]
Message-ID: <20070126143555.GL11525@frankl.hpl.hp.com> (raw)

Hello,

I ran into compiler warnings with the perfmon code when I tried
using test() and __set_bit() on i386. 

For some reason, the i386 bitops functions use unsigned long * for
the address whereas x86-64/ia64 use void *.

I do not quite understand why such difference?
Is this just for historical reasons?

Thanks.
