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.

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.

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.
