Update.
1997-04-02 16:28 Ulrich Drepper <drepper@cygnus.com> * grp/fgetgrent.c: Don't use fixed buffer length. Allow dynamic adjustment if the underlying function say it is too small. * pwd/fgetpwent.c: Likewise. * shadow/fgetspent.c: Likewise. * shadow/sgetspent.c: Likewise. * grp/fgetgrent_r.c (__fgetgrent_r): If `parse_result' returns -1 this means there was not enough room for the gr_mem array. * nss/nss_files/files-XXX.c: Leave loop and return error if `parse_result' returns -1. * nss/nss_files/files-parse.c (parse_line): Return -1 if parsing of trailing list fails because of low memory. (parse_list): Rewrite. The logic was completly incorrect since the checks for overflowing the array were not executed when needed. * shadow/sgetspent_r.c: Only a return value > 0 from parse_line signals success. * nss/getXXbyYY.c: Make sure NULL is returned if we ran out of memory. * nss/getXXent.c: Likewise. * stdlib/strtod.c (SET_MANTISSA): Make sure that at least one bit is set in mantissa. * stdlib/strtof.c: Likewise. * stdlib/strtold.c: Likewise. * wcsmbs/wcstof.c: Likewise. * wcsmbs/wcstold.c: Likewise. * sysdeps/libm-ieee754/s_nan.c: Use strtod is parameter is not empty string. * sysdeps/libm-ieee754/s_nanf.c: Likewise. * sysdeps/libm-ieee754/s_nanld.c: Likewise. 1997-04-02 13:56 Ulrich Drepper <drepper@cygnus.com> * manual/errno.texi: Add description of strerror_r. 1997-04-01 19:07 H.J. Lu (hjl@gnu.ai.mit.edu) * manual/errno.texi: Add ENOMEDIUM and EMEDIUMTYPE. 1997-04-02 13:55 Ulrich Drepper <drepper@cygnus.com> * sysdeps/gnu/errlist.awk: The Texinfo file is named errno.texi. 1997-03-30 10:59 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/m68k/fpu/s_cexp.c: New file. * sysdeps/m68k/fpu/s_cexpf.c: New file. * sysdeps/m68k/fpu/s_cexpl.c: New file. * sysdeps/m68k/fpu/s_nearbyint.c: New file. * sysdeps/m68k/fpu/s_nearbyintf.c: New file. * sysdeps/m68k/fpu/s_nearbyintl.c: New file. * sysdeps/m68k/fpu/s_trunc.c: New file. * sysdeps/m68k/fpu/s_truncf.c: New file. * sysdeps/m68k/fpu/s_truncl.c: New file. * sysdeps/m68k/fpu/s_modf.c: Rewritten. * sysdeps/m68k/fpu/s_modff.c: Adapted. * sysdeps/m68k/fpu/s_modfl.c: Likewise. * sysdeps/m68k/fpu/e_atan2.c: Use __signbit inline. * sysdeps/m68k/fpu/e_pow.c: Likewise. Write 0.0/0.0 for NaN. Fix typo in test for `y = 0.5'. * sysdeps/m68k/fpu/__math.h: Define __trunc, __signbit, __nearbyint. Remove __modf. * sysdeps/m68k/Makefile (CFLAGS-s_copysignl.c) [$(subdir)=math]: Define for gcc bug workaround. * math/libm-test.c (log2_test): Add epsilon for long double to "log2 (e)" and "log2 (16)". (modf_test): Fix test name. (sqrt_test): Add missing FUNC. 1997-03-29 16:24 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sunrpc/Makefile (CFLAGS-xrquota.c): Fix typo in variable name. 1997-03-28 20:56 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * stdlib/stdlib.h: Declare __clearenv. 1997-03-28 18:03 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/libm-ieee754/s_asinhl.c: Fix Ulrich Dreppers mangling of the last change. 1997-03-28 17:55 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * configure.in: Call AC_CANONICAL_BUILD before referencing $build. Fix test for BUILD_CC. 1997-04-02 01:29 Philip Blundell <pjb27@cam.ac.uk> * sysdeps/libm-ieee754/s_log2f.c (__log2f): Fix typo. 1997-03-31 18:53 Philip Blundell <pjb27@cam.ac.uk> * sysdeps/unix/sysv/linux/net/route.h: Add new IPv6 definitions. 1997-04-01 14:08 Ulrich Drepper <drepper@cygnus.com> * sysdeps/i386/memset.c: Fix typo. * sysdeps/stub/fchmod.c: Fix typo. * sysdeps/stub/fchdir.c: Fix typo. Reported by Fila Kolodny <fila@ibi.com>.

+
+ # 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.
