Subject: bitwise operations on registers
Date: Sun, 10 Mar 2002 23:50:00 -0000	[thread overview]
Message-ID: <3C8C615E.5D4F0A6B@zip.com.au> (raw)

I'm sure I'm doing something silly.

(gdb) p $esp + 4
$15 = (void *) 0xca9c3ea4
(gdb) p $esp & 4
Argument to arithmetic operation not a number or boolean.
(gdb) 

I don't seem to be able to perform the `&' and `|' arithmetic
operators against machine registers.

GNU gdb Red Hat Linux (5.1.1-1)

Thanks.
