-/* The algorithm here uses the following techniques:
-
-   1) Given a word 'x', we can test to see if it contains any 0 bytes
-      by subtracting 0x01010101, and seeing if any of the high bits of each
-      byte changed from 0 to 1. This works because the least significant
-      0 byte must have had no incoming carry (otherwise it's not the least
-      significant), so it is 0x00 - 0x01 == 0xff. For all other
-      byte values, either they have the high bit set initially, or when
-      1 is subtracted you get a value in the range 0x00-0x7f, none of which
-      have their high bit set. The expression here is
-      (x + 0xfefefeff) & ~(x | 0x7f7f7f7f), which gives 0x00000000 when
-      there were no 0x00 bytes in the word.
-
-   2) Given a word 'x', we can test to see _which_ byte was zero by
-      calculating ~(((x & 0x7f7f7f7f) + 0x7f7f7f7f) | x | 0x7f7f7f7f).
-      This produces 0x80 in each byte that was zero, and 0x00 in all
-      the other bytes. The '| 0x7f7f7f7f' clears the low 7 bits in each
-      byte, and the '| x' part ensures that bytes with the high bit set
-      produce 0x00. The addition will carry into the high bit of each byte
-      iff that byte had one of its low 7 bits set. We can then just see
-      which was the most significant bit set and divide by 8 to find how
-      many to add to the index.
-      This is from the book 'The PowerPC Compiler Writer's Guide',
-      by Steve Hoxey, Faraydon Karim, Bill Hay and Hank Warren.
-
-   We deal with strings not aligned to a word boundary by taking the
-   first word and ensuring that bytes not part of the string
-   are treated as nonzero. To allow for memory latency, we unroll the
-   loop a few times, being careful to ensure that we do not read ahead
-   across cache line boundaries.
-
-   Questions to answer:
-   1) How long are strings passed to strlen? If they're often really long,
-   we should probably use cache management instructions and/or unroll the
-   loop more. If they're often quite short, it might be better to use
-   fact (2) in the inner loop than have to recalculate it.
-   2) How popular are bytes with the high bit set? If they are very rare,
-   on some processors it might be useful to use the simpler expression
-   ~((x - 0x01010101) | 0x7f7f7f7f) (that is, on processors with only one
-   ALU), but this fails when any character has its high bit set.  */

-/* Some notes on register usage: Under the SVR4 ABI, we can use registers
-   0 and 3 through 12 (so long as we don't call any procedures) without
-   saving them. We can also use registers 14 through 31 if we save them.
-   We can't use r1 (it's the stack pointer), r2 nor r13 because the user
-   program may expect them to hold their usual value if we get sent
-   a signal. Integer parameters are passed in r3 through r10.
-   We can use condition registers cr0, cr1, cr5, cr6, and cr7 without saving
-   them, the others we must save.  */
