+/* Most of the fields are self-explanatory.  'sr0' is the next
+   instruction to execute, from SRR0, which may have some relationship
+   with the instruction that caused the exception.  'r3*' is the value
+   that will be returned in register 3 when the current system call
+   returns.  'sr1' is SRR1, bits 16-31 of which are copied from the MSR:
+
+   16 - External interrupt enable
+   17 - Privilege level (1=user, 0=supervisor)
+   18 - FP available
+   19 - Machine check enable (if clear, processor locks up on machine check)
+   20 - FP exception mode bit 0 (FP exceptions recoverable)
+   21 - Single-step trace enable
+   22 - Branch trace enable
+   23 - FP exception mode bit 1
+   25 - exception prefix (if set, exceptions are taken from 0xFFFnnnnn,
+        otherwise from 0x000nnnnn).
+   26 - Instruction address translation enabled.
+   27 - Data address translation enabled.
+   30 - Exception is recoverable (otherwise, don't try to return).
+   31 - Little-endian mode enable.
+
+   'Trap' is the address of the exception:
+
+   00200 - Machine check exception (memory parity error, for instance)
+   00300 - Data access exception (memory not mapped, see dsisr for why)
+   00400 - Instruction access exception (memory not mapped)
+   00500 - External interrupt
+   00600 - Alignment exception (see dsisr for more information)
+   00700 - Program exception (illegal/trap instruction, FP exception)
+   00800 - FP unavailable (should not be seen by user code)
+   00900 - Decrementer exception (for instance, SIGALRM)
+   00A00 - I/O controller interface exception
+   00C00 - System call exception (for instance, kill(3)).
+   00E00 - FP assist exception (optional FP instructions, etc.)
+
+   'dar' is the memory location, for traps 00300, 00400, 00600, 00A00.
+   'dsisr' has the following bits under trap 00300:
+   0 - direct-store error exception
+   1 - no page table entry for page
+   4 - memory access not permitted
+   5 - trying to access I/O controller space or using lwarx/stwcx on
+       non-write-cached memory
+   6 - access was store
+   9 - data access breakpoint hit
+   10 - segment table search failed to find translation (64-bit ppcs only)
+   11 - I/O controller instruction not permitted
+   For trap 00400, the same bits are set in SRR1 instead.
+   For trap 00600, bits 12-31 of the DSISR set to allow emulation of
+   the instruction without actually having to read it from memory.

+/* 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.  */
