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"? :)
