+/* 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. */
