From fe0ec73edb48eff3785f29ddbac75cae5f8b361b Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Thu, 13 Nov 1997 00:21:19 +0000 Subject: Update. 1997-11-13 01:07 Ulrich Drepper * manual/arith.texi: Update documentation according to most recent ISO C 9X draft. Document fma, fdim, fmin, and fmax. * manual/math.texi: Allow multiple defitino of mul etc. * math/complex.h (I): Define using _Complex_U not _Imaginary_I. * math/libm-test.c: Add tests for fma. * math/math.h: Describe DECIMAL_DIG macro. Pretty print. * sysdeps/alpha/fpu/bits/mathdef.h: Define INFINITY as of type float. Define DECIMAL_DIG. * sysdeps/generic/bits/mathdef.h: Likewise. * sysdeps/i386/bits/mathdef.h: Likewise. * sysdeps/m68k/fpu/bits/mathdef.h: Likewise. * sysdeps/powerpc/bits/mathdef.h: Likewise. * sysdeps/sparc/fpu/bits/mathdef.h: Likewise. * sysdeps/ieee754/bits/nan.h: Define NAN as of type float. * sysdeps/m68k/bits/nan.h. Likewise. Remove NANF and NANL. 1997-11-12 17:50 Ulrich Drepper * sunrpc/xcrypt.c: Don't process #ident preprocessor instruction. Reported by Philip Blundell . * string/strndup.c: Use K&R like definition. * sysdeps/unix/sysv/linux/getcwd.c: New file. Use kernel information instead of longish search for the name. * sysdeps/posix/getcwd.c: Add support for use of the code as a backup solution. 1997-11-12 15:31 Philip Blundell * sysdeps/unix/sysv/linux/arm/sysdep.h (SYS_ify): Don't add SWI_BASE in twice. * sysdeps/unix/sysv/linux/arm/profil-counter.h (profil_counter): Use correct name to access PC. * sysdeps/unix/arm/sysdep.S: Include not . * sysdeps/generic/bits/types.h: Add __ino64_t and __off64_t. * sysdeps/generic/bits/stat.h: Add struct stat64. 1997-11-12 16:08 Ulrich Drepper * intl/loadmsgcat.c [_LIBC] (fstat): Don't define as __fstat since now we have a definition as _fxstat. * libio/fileops.c: Likewise. * libio/oldfileops.c: Likewise. Reported by Andreas Jaeger . 1997-11-12 Andreas Jaeger * sysdeps/wordsize-32/inttypes.h (SIG_ATOMIC_MAX): Correct value. * sysdeps/wordsize-64/inttypes.h (SIG_ATOMIC_MAX): Likewise. 1997-11-11 Paul Eggert Add overflow checking for 64-bit time_t and 32-bit int. * time/time.h (__offtime): Now returns int. * time/offtime.c (__offtime): Return nonzero if successful; check for tm_year overflow. (DIV): New macro. (LEAPS_THRU_END_OF): Handle negative years correctly. * time/tzset.c (__tz_convert): Return NULL if offtime cannot convert. * time/mktime.c (ranged_convert): New function. (ydhms_tm_diff): Return nonzero if TP is null. (__mktime_internal): Handle cases correctly even if they are near or past the limits of time_t values that can be broken down to struct tm. (print_tm, check_result, main): Diagnose localtime failures. * manual/time.texi: Document the fact that localtime returns 0 if the time can't be represented. 1997-11-12 06:03 Ulrich Drepper * time/strftime.c (memset_space, memset_zero): Use MEMPCPY, not mempcpy. Patch by Ken'ichi Handa . * manual/time.texi: Document %F and %f format for strftime. * manual/arith.texi: Document copysign, nextafter and nan. 1997-11-06 Andreas Jaeger * test-installation.pl: New file. Tests for some installation problems. --- sysdeps/m68k/bits/nan.h | 59 ----------------------------------------- sysdeps/m68k/fpu/bits/mathdef.h | 7 +++-- 2 files changed, 5 insertions(+), 61 deletions(-) delete mode 100644 sysdeps/m68k/bits/nan.h (limited to 'sysdeps/m68k') diff --git a/sysdeps/m68k/bits/nan.h b/sysdeps/m68k/bits/nan.h deleted file mode 100644 index b4efddf..0000000 --- a/sysdeps/m68k/bits/nan.h +++ /dev/null @@ -1,59 +0,0 @@ -/* `NAN' constants for m68k. - Copyright (C) 1997 Free Software Foundation, Inc. - This file is part of the GNU C Library. - - The GNU C Library is free software; you can redistribute it and/or - modify it under the terms of the GNU Library General Public License as - published by the Free Software Foundation; either version 2 of the - License, or (at your option) any later version. - - The GNU C Library is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
