Update. cvs/libc-ud-971112
1997-11-13 01:07 Ulrich Drepper <drepper@cygnus.com> * 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 <drepper@cygnus.com> * sunrpc/xcrypt.c: Don't process #ident preprocessor instruction. Reported by Philip Blundell <pb@nexus.co.uk>. * 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 <pb@nexus.co.uk> * 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 <bits/errno.h> not <errnos.h>. * 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 <drepper@cygnus.com> * 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 <aj@arthur.rhein-neckar.de>. 1997-11-12 Andreas Jaeger <aj@arthur.rhein-neckar.de> * sysdeps/wordsize-32/inttypes.h (SIG_ATOMIC_MAX): Correct value. * sysdeps/wordsize-64/inttypes.h (SIG_ATOMIC_MAX): Likewise. 1997-11-11 Paul Eggert <eggert@twinsun.com> 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 <drepper@cygnus.com> * time/strftime.c (memset_space, memset_zero): Use MEMPCPY, not mempcpy. Patch by Ken'ichi Handa <handa@etl.go.jp>. * manual/time.texi: Document %F and %f format for strftime. * manual/arith.texi: Document copysign, nextafter and nan. 1997-11-06 Andreas Jaeger <aj@arthur.rhein-neckar.de> * test-installation.pl: New file. Tests for some installation problems.
