Thu May 30 11:24:05 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>cvs/libc-960602cvs/libc-960601cvs/libc-960531
* po/header.pot: Replace with exact boilerplate pinard dictates. * sysdeps/i386/strtok.S (Lillegal_argument): Remove this code to set errno and the check that jumped to it. * sysdeps/mach/hurd/Makefile (errnos.d): Use $(sed-remove-objpfx). Thu May 30 03:21:57 1996 Ulrich Drepper <drepper@cygnus.com> * FAQ: Document need of gperf program for developers. * elf/elf.h: Fix typos in comments. * libio/stdio.h [!__STRICT_ANSI__ || _POSIX_SOURCE]: Add prototypes for `ctermid' and `cuserid'. * locale/programs/locale.c: Switch to user selected locale before printing variables. * math/Makefile [$(long-double-fcts)==yes]: Define long-m-routines and long-c-routines. Only if the `long double' data type is available we need to compile the functions. (libm-routines): Add $(long-m-routines). (routines): Remove isinfl, isnanl. Use new file s_isinfl and s_isnanl instead if `long double' is available. * math/math.h: Include <mathcalls.h> again to define `long double' functions. * math/math_private.h: Define data types, prototypes and access macros for `long double'. * stdlib/stdlib.h: Add prototypes for `strtoll' and `strtoull'. [GCC2 && OPTIMIZE]: Define strto{,u}ll as inline function which calls __strto{,u}q_internal. * stdlib/strfmon.c: Replace PTR by `void *'. * stdlib/strtoq.c: Define strtoll as weak alias. * stdlib/strtouq.c: Define strtoull as weak alias. * string/tester.c: Correct `strsep' test. * sysdeps/generic/strsep.c: Make compatible with BSD version. Trailing characters of skip set are not skipped. In this case empty tokens are returned. * sysdeps/i386/isinfl.c, sysdeps/i386/isnanl.c, sysdeps/ieee754/isinf.c, sysdeps/ieee754/isinfl.c, sysdeps/ieee754/isnan.c, sysdeps/ieee754/isnanl.c: Removed. We now use the versions part of libm. * sysdeps/i386/strsep.S: Removed. Generic C version is of similar speed. * sysdeps/i386/strtok.S: Remove support for `strsep'. * sysdeps/libm-i387/e_acosl.S, sysdeps/libm-i387/s_ceill.S, sysdeps/libm-i387/s_copysignl.S, sysdeps/libm-i387/s_finitel.S, sysdeps/libm-i387/s_floorl.S, sysdeps/libm-i387/s_isinfl.c, sysdeps/libm-i387/s_isnanl.c, sysdeps/libm-i387/s_nextafterl.c, sysdeps/libm-i387/s_rintl.S, sysdeps/libm-i387/s_significandl.S: New i387 specific math functions implementing `long double' versions. * sysdeps/libm-ieee754/s_ceill.c, sysdeps/libm-ieee754/s_copysignl.c, sysdeps/libm-ieee754/s_fabsl.c, sysdeps/libm-ieee754/s_finitel.c, sysdeps/libm-ieee754/s_floorl.c, sysdeps/libm-ieee754/s_isinfl.c, sysdeps/libm-ieee754/s_isnanl.c, sysdeps/libm-ieee754/s_nextafterl.c, sysdeps/libm-ieee754/s_rintl.c, sysdeps/libm-ieee754/s_scalbnl.c, sysdeps/libm-ieee754/s_significandl.c: New generic `long double' versions of libm functions. * sysdeps/libm-i387/e_exp.S: Add a few comments to explain the Intel FPU nonsense. * sysdeps/libm-i387/s_ceil.S, sysdeps/libm-i387/s_ceilf.S, sysdeps/libm-i387/s_floor.S, sysdeps/libm-i387/s_floorf.S: Correct handling of local variables. The old version created a stack frame but stored the values outside. * sysdeps/libm-ieee754/s_isinf.c, sysdeps/libm-ieee754/s_isnan.c [!NO_LONG_DOUBLE]: Define alias with `long double' versions name. * login/pututline_r.c: Include sys/stat.h. Fix typos. according to currently used locale for category LC_CTYPE by inet_nsap_ntoa. Now in <arpa/inet.h>. _IO_dup2 to contain complete parameter list.
