Thu May 30 11:24:05 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
* 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,

New i387 specific math functions implementing `long double'
versions.

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.

Wed May 29 00:57:37 1996 David Mosberger-Tang <davidm@azstarnet.com>
* time/Makefile (tests): Add test-tz.
* time/test-tz.c: New test.
* time/clocktest.c: Rewrite to test more meaningfully.
* sysdeps/unix/sysv/linux/syscalls.list: Add bdflush,
create_module, delete_module, get_kernel_syms, init_module,
klogctl.
* sysdeps/unix/sysv/linux/sys/param.h (MAXSYMLINKS): Define as 5
instead of SYMLOOP_MAX, which is nowhere to be found.
* sysdeps/unix/sysv/linux/sys/msq_buf.h,
sysdeps/unix/sysv/linux/sys/sem_buf.h,
sysdeps/unix/sysv/linux/sys/shm_buf.h [__USE_MISC]: Add more
control ops and datastructures.
* sysdeps/unix/sysv/linux/sys/io.h: New file declaring low-level
I/O related functions.
* sysdeps/unix/sysv/linux/sys/kdaemon.h: New file declaring kernel
daemon related functions/operations.
* sysdeps/unix/sysv/linux/sys/klog.h: New file declaring kernel
logging related functions/operations.
* sysdeps/unix/sysv/linux/sys/module.h: New file declaring kernel
module related functions/operations.
* sysdeps/unix/sysv/linux/speed.c: Only do "mention this twice" hack
for non-Alpha based Linux systems.
* sysdeps/unix/sysv/linux/alpha/speed.c: Remove.
* sysdeps/unix/sysv/linux/Makefile (headers): Add sys/module.h,
sys/io.h, sys/klog.h, and sys/kdaemon.h.
* sysdeps/unix/sysdep.h (END): Define empty END macro for
platforms that don't need some sort of end directive at the
end of functions.
* sysdeps/unix/make-syscalls.sh: Emit END($strong) at end of
syscall wrapper to allow correct generation of debugging
information.
* sysdeps/unix/alpha/sysdep.h (END): Redefine to use .end
directive for both ELF and ECOFF.
(ret): Delete macro. It was a dangerous macro and unnecessary
since the Alpha assemblers recognizes "ret" as a macro themselves.
* sysdeps/gnu/utmpbits.h (struct utmp): Move ut_tv behind
ut_session to guarantee long alignment. This is important for
Linux/Alpha since ut_tv.tv_sec is 32 bits and time_t is 64 bits.
This will all get cleaned up as programs start to use ut_tv
instead ut_time.
* sysdeps/alpha/divrem.h: Include <sysdep.h> instead of <*/regdef.h>.
* sysdeps/alpha/bsd-_setjmp.S (setjmp): Renamed entry point to
_setjmp.
* sysdeps/alpha/_mcount.S, sysdeps/alpha/bb_init_func.S,
sysdeps/alpha/bsd-_setjmp.S, sysdeps/alpha/bsd-setjmp.S,
sysdeps/alpha/copysign.S, sysdeps/alpha/divrem.h,
sysdeps/alpha/fabs.S, sysdeps/alpha/ffs.S, sysdeps/alpha/htonl.S,
sysdeps/alpha/htons.S, sysdeps/alpha/memchr.S,
sysdeps/alpha/setjmp.S, sysdeps/alpha/strlen.S,
sysdeps/unix/sysv/linux/alpha/ieee_get_fp_control.S,
sysdeps/unix/sysv/linux/alpha/ieee_set_fp_control.S,
sysdeps/unix/sysv/linux/alpha/llseek.S,
sysdeps/unix/sysv/linux/alpha/pipe.S,
sysdeps/unix/sysv/linux/alpha/sigsuspend.S,
sysdeps/unix/sysv/linux/alpha/sysdep.S: Use END macro instead of
.end directive.
* csu/initfini.c (_fini): Tell gcc that _fini is not a leaf
function by having it contain a dummy function call.
* configure.in (config_machine): Don't make ELF the default for
Linux/Alpha just yet (use --with-elf instead).
(.init/.fini check): Generate .text to ensure function start and
end are in same section.
* sysdeps/unix/bsd/osf/alpha/brk.S,
sysdeps/unix/sysv/linux/alpha/brk.S (__curbrk): Store the entire
break value, not just the low 32 bits to accomodate large
memories.
Tue May 28 10:46:04 1996 Richard Henderson <rth@tamu.edu>
* sysdeps/unix/sysv/linux/alpha/brk.S: Rather than attempt to
dynamically resolve _end for initializing __curbrk, support the
brk(0) query idiom.
* sysdeps/alpha/bb_init_func.S: Don't make `init' an external symbol.
* sysdeps/alpha/bsd-_setjmp.S: The function is _setjmp not setjmp.
Sun May 26 22:17:38 1996 Richard Henderson <rth@tamu.edu>
* stdlib/lcong48_r.c, stdlib/seed48_r.c, stdlib/strtod.c,
stdlib/strtol.c: Include <string.h> for mem* and str* fns used.
Thu May 23 02:15:56 1996 David Mosberger-Tang <davidm@azstarnet.com>
* sysdeps/unix/sysv/linux/Makefile (headers): Add sys/io.h,
sys/klog.h, and sys/kdaemon.h.
* sysdeps/unix/sysv/linux/sys/io.h: New file.
* sysdeps/unix/sysv/linux/sys/klog.h: Ditto.
* sysdeps/unix/sysv/linux/sys/kdaemon.h: Ditto.
* sysdeps/unix/alpha/sysdep.h (ret): Remove macro. It is
dangerous and unnecessary since both OSF/1 as and gas define "ret"
as a pseudo-instruction.
Sat Jun 1 17:18:21 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
* time/tzset.c (__tzset): Clear tz_rules name pointers after freeing
them. Bug found by David Mosberger-Tang.
* sysdeps/posix/tempname.c (__stdio_gen_tempname): Use __ptr_t instead
of PTR.
* extra-lib.mk (extra-objs): Use patsubst intead of $(A:=B) syntax
to work around Make bug when A contains var ref.
Fri May 31 18:27:52 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
* string/string.h [__USE_MISC]: Declare basename; OSF/1 puts it here.
* sysdeps/unix/sysv/linux/syscalls.list (getpgid, setpgid): Define __
strong names and [gs]etpgid as weak aliases.
* math/math_private.h (GET_LDOUBLE_EXP): Add missing backslash.

prototypes for `ctermid' and `cuserid'.

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).

calls __strto{,u}q_internal.

* stdlib/strtouq.c: Define strtoull as weak alias.
