commentary by Jim Blandy (jimb@ai.mit.edu);

/* Normally, this uses
|

((xword - 0x0101010101010101) & 0x8080808080808080) test
|
||||
to find out if any byte in xword could be zero. This is fast, but
|
||||
also gives false alarm for any byte in range 0x81-0xff. It does
|
||||
not matter for correctness, as if this test tells us there could
|
||||
be some zero byte, we check it byte by byte, but if bytes with
|
||||
high bits set are common in the strings, then this will give poor
|
||||
performance. You can #define EIGHTBIT_NOT_RARE and the algorithm
|
||||
will use one tick slower, but more precise test
|
||||
((xword - 0x0101010101010101) & (~xword) & 0x8080808080808080),
|
||||
which does not give any false alarms (but if some bits are set,
|
||||
one cannot assume from it which bytes are zero and which are not).
|
||||
It is yet to be measured, what is the correct default for glibc
|
||||
in these days for an average user.
