+
+[A22] {UD} The problem is that the IPv6 development still has not reached
+a point where it is stable. There are still lots of incompatible changes
+made and the libc headers have to follow.
+
+Currently (as of 970401) according to Philip Blundell <pjb27@cam.ac.uk>
+the required kernel version is 2.1.30.

+[Q23] ``When compiling GNU libc I get lots of errors saying functions
+ in glibc are duplicated in libgcc.''
+
+[A23] {EY} This is *exactly* the same problem that I was having. The
+problem was due to the fact that the autoconfigure didn't correctly
+detect that linker flag --no-whole-archive was supported in my linker.
+In my case it was because I had run ./configure with bogus CFLAGS, and
+the test failed.
+
+One thing that is particularly annoying about this problem is that
+once this is misdetected, running configure again won't fix it unless
+you first delete config.cache.
+
+{UD} Starting with glibc-2.0.3 there should be a better test to avoid
+some problems of this kind. The setting of CFLAGS is checked at the
+very beginning and if it is not usable `configure' will bark.

+
+At most @var{n} characters are written (including the NUL byte) so it is

+
+ # 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), nor r2 or r13 because the user
+ # program may expect them to be 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.
