LONGWORD fails to change any of the hole bits of LONGWORD.
|
|
|
|
|
|
|
|
1) Is this safe? Will it catch all the zero bytes?
|
|
|
|
Suppose there is a byte with all zeros. Any carry bits
|
|
|
|
propagating from its left will fall into the hole at its
|
|
|
|
least significant bit and stop. Since there will be no
|
|
|
|
carry from its most significant bit, the LSB of the
|
|
|
|
byte to the left will be unchanged, and the zero will be
|
|
|
|
detected.
|
|
|
|
|
|
|
|
2) Is this worthwhile? Will it ignore everything except
|
|
|
|
zero bytes? Suppose every byte of LONGWORD has a bit set
|
|
|
|
somewhere. There will be a carry into bit 8. If bit 8
|
|
|
|
is set, this will carry into bit 16. If bit 8 is clear,
|
|
|
|
one of bits 9-15 must be set, so there will be a carry
|
|
|
|
into bit 16. Similarly, there will be a carry into bit
|
|
|
|
24. If one of bits 24-30 is set, there will be a carry
|
|
|
|
into bit 31, so all of the hole bits will be changed.
|
|
|
|
|
|
|
|
The one misfire occurs when bits 24-30 are clear and bit
|
|
|
|
31 is set; in this case, the hole at bit 31 is not
|
|
|
|
changed. If we had access to the processor carry flag,
|
|
|
|
we could close this loophole by putting the fourth hole
|
|
|
|
at bit 32!
|
|
|
|
|
|
|
|
So it ignores everything except 128's, when they're aligned
|
|
|
|
properly.
|
|
|
|
|
|
|
|
3) But wait! Aren't we looking for C, not zero?
|
|
|
|
Good point. So what we do is XOR LONGWORD with a longword,
|
|
|
|
each of whose bytes is C. This turns each byte that is C
|
|
|
|
into a zero. */
