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 as well as 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. */

/* Instead of the traditional loop which tests each byte, we will test a

longword at a time. The tricky part is testing if *any of the four*
|
||||
bytes in the longword in question are equal to c. We first use an xor
|
||||
with repeated_c. This reduces the task to testing whether *any of the
|
||||
four* bytes in longword1 is zero.
|
||||
|
||||
We compute tmp =
|
||||
((longword1 - repeated_one) & ~longword1) & (repeated_one << 7).
|
||||
That is, we perform the following operations:
|
||||
1. Subtract repeated_one.
|
||||
2. & ~longword1.
|
||||
3. & a mask consisting of 0x80 in every byte.
|
||||
Consider what happens in each byte:
|
||||
- If a byte of longword1 is zero, step 1 and 2 transform it into 0xff,
|
||||
and step 3 transforms it into 0x80. A carry can also be propagated
|
||||
to more significant bytes.
|
||||
- If a byte of longword1 is nonzero, let its lowest 1 bit be at
|
||||
position k (0 <= k <= 7); so the lowest k bits are 0. After step 1,
|
||||
the byte ends in a single bit of value 0 and k bits of value 1.
|
||||
After step 2, the result is just k bits of value 1: 2^k - 1. After
|
||||
step 3, the result is 0. And no carry is produced.
|
||||
So, if longword1 has only non-zero bytes, tmp is zero.
|
||||
Whereas if longword1 has a zero byte, call j the position of the least
|
||||
significant zero byte. Then the result has a zero at positions 0, ...,
|
||||
j-1 and a 0x80 at position j. We cannot predict the result at the more
|
||||
significant bytes (positions j+1..3), but it does not matter since we
|
||||
already have a non-zero bit at position 8*j+7.
|
||||
|
||||
So, the test whether any byte in longword1 is zero is equivalent to
|
||||
testing whether tmp is nonzero. */

|

|

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 as well as 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
|

bytes in the longword in question are equal to c. We first use an xor
|
||||
with repeated_c. This reduces the task to testing whether *any of the
|
||||
four* bytes in longword1 is zero.
|
||||
|
||||
We compute tmp =
|
||||
((longword1 - repeated_one) & ~longword1) & (repeated_one << 7).
|
||||
That is, we perform the following operations:
|
||||
1. Subtract repeated_one.
|
||||
2. & ~longword1.
|
||||
3. & a mask consisting of 0x80 in every byte.
|
||||
Consider what happens in each byte:
|
||||
- If a byte of longword1 is zero, step 1 and 2 transform it into 0xff,
|
||||
and step 3 transforms it into 0x80. A carry can also be propagated
|
||||
to more significant bytes.
|
||||
- If a byte of longword1 is nonzero, let its lowest 1 bit be at
|
||||
position k (0 <= k <= 7); so the lowest k bits are 0. After step 1,
|
||||
the byte ends in a single bit of value 0 and k bits of value 1.
|
||||
After step 2, the result is just k bits of value 1: 2^k - 1. After
|
||||
step 3, the result is 0. And no carry is produced.
|
||||
So, if longword1 has only non-zero bytes, tmp is zero.
|
||||
Whereas if longword1 has a zero byte, call j the position of the least
|
||||
significant zero byte. Then the result has a zero at positions 0, ...,
|
||||
j-1 and a 0x80 at position j. We cannot predict the result at the more
|
||||
significant bytes (positions j+1..3), but it does not matter since we
|
||||
already have a non-zero bit at position 8*j+7.
|
||||
|
||||
So, the test whether any byte in longword1 is zero is equivalent to
|
||||
testing whether tmp is nonzero. */
