|
||||
|

[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.

The @code{strerror_r} function works like @code{strerror} but instead of
|

returning the error message in a statically allocated buffer shared by
|
||||
all threads in the process, it writes the message string in the user
|

supplied buffer starting at @var{buf} with the length of @var{n} bytes.
|

|

At most @var{n} characters are written (including the NUL byte) so it is
|
||||
up to the user to select the buffer large enough.
|
||||
|
||||
This function should always be used in multi-threaded programs since

there is no way to guarantee the string returned by @code{strerror}

really belongs to the last call of the current thread.

# Boston, MA 02111-1307, USA.
|
||||
|
||||
# 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.
