linearize bug?

[Jeff Garzik <jeff@garzik.org>]

Given the following C code:
#include <stdlib.h>

int foo(void)
{
         int i;

         i = 42;
         i += rand();

         return i;
}

test-linearize seems to give me the following output, which indicates 
that pseudo %r1 is "dead" immediately before it is used:

foo:
.L0x2b52beecd010:
         <entry-point>
         call.32     %r1 <- rand
         dead        %r1
         add.32      %r4 <- %r1, $42
         dead        %r4
         ret.32      %r4

Am I just confused about the meaning of "dead"?   :)
