- the four* bytes in the longword in question are equal to NUL or
- c. We first use an xor with repeated_c. This reduces the task
- to testing whether *any of the four* bytes in longword1 or
- longword2 is zero.
-
- Let's consider longword1. 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.
-
- The test whether any byte in longword1 or longword2 is zero is equivalent
- to testing whether tmp1 is nonzero or tmp2 is nonzero. We can combine
- this into a single test, whether (tmp1 | tmp2) is nonzero.
-
- This test can read more than one byte beyond the end of a string,
- depending on where the terminating NUL is encountered. However,
- this is considered safe since the initialization phase ensured
- that the read will be aligned, therefore, the read will not cross
- page boundaries and will not cause a fault. */

-dnl Test whether posix_spawn actually works.
-dnl posix_spawn on AIX 5.3..6.1 has two bugs:
-dnl 1) When it fails to execute the program, the child process exits with
-dnl exit() rather than _exit(), which causes the stdio buffers to be
-dnl flushed. Reported by Rainer Tammer.
-dnl 2) The posix_spawn_file_actions_addopen function does not support file
-dnl names that contain a '*'.
-dnl posix_spawn on AIX 5.3..6.1 has also a third bug: It does not work
-dnl when POSIX threads are used. But we don't test against this bug here.
