Update.
Thu Aug 8 01:41:43 1996 Ulrich Drepper <drepper@cygnus.com>
* elf/Makefile: Undo change of Tue Aug 6 14:27:11 1996.
* elf/dl-support: Add definition of `_dl_sysdep_read_whole_file'.
Thu Aug 8 01:15:59 1996 Ulrich Drepper <drepper@cygnus.com>
* sysdeps/i386/fpu_control.h (_FPU_DEFAULT, _FPU_IEEE): Set
to 0x137f to allow long double operations.
Sun Aug 4 13:12:05 1996 Richard Henderson <rth@tamu.edu>
Bug Fixes:
* nss/nsswitch.c (_res): Remove redundant variable definition.
The real one is in resolve/res_init.c, and having both prevents
using -fno-common when building the shared library.
* sunrpc/rpc_prot.c (_null_auth): Same. Original is in rpc_common.c.
* sysdeps/unix/sysv/linux/alpha/brk.S: When PIC, define __curbrk as
a .bss object not a COMMON symbol.
* sysdeps/alpha/bsd-_setjmp.S, sysdeps/alpha/bsd-setjmp.S: Must load
$gp before referencing __sigsetjmp symbol. Retain LITUSE for same.
Optimizations:
* sysdeps/alpha/strlen.S: Rearrange first-word setup and thense the
main loop for better dual-issue on EV5. Rearrange binary search to
pipeline better and trim one instruction.
Cosmetic Changes:
* time/localtime.c (localtime_r): Move lock declaration back next to
the comment where it was before the 960724 change.
* INSTALL, manual/maint.texi: alpha-gnu-linux -> alpha-ANYTHING-linux.
The second word is supposed to be the hardware manufacturer.
* sysdeps/alpha/_mcount.S: Retain LITUSE for __mcount.
* sysdeps/alpha/setjmp.S: Retain LITUSE for __sigsetjmp_aux.
* sysdeps/alpha/divrem.h: More local labels, retain LITUSE for _mcount.
* sysdeps/alpha/alphaev5/add_n.S, sysdeps/alpha/alphaev5/lshift.S,
sysdeps/alpha/alphaev5/rshift.S, sysdeps/alpha/alphaev5/sub_n.S:
Same cleanups as with EV4 GMP stuff.
Tue Jul 25 03:30:56 1996 Richard Henderson <rth@tamu.edu>
* sysdeps/unix/sysv/linux/Makefile [misc] (sysdep_routines): Add clone.
* sysdeps/unix/sysv/linux/alpha/clone.S: New file.
* sysdeps/unix/sysv/linux/i386/clone.S: New file.
Sun Aug 4 00:12:41 1996 David Mosberger-Tang <davidm@azstarnet.com>
* sysdeps/unix/sysv/linux/gnu/types.h: Declare __fd_mask as
`unsigned long'.
* misc/sys/select.h: Declare fd_mask as alias of __fd_mask.
Sat Aug 3 16:20:02 1996 David Mosberger-Tang <davidm@azstarnet.com>
* sysdeps/unix/sysv/linux/alpha/ioperm.c (platform): Add entry for
Mikasa.
* socket/sys/socket.h (send, __send, sendto): Declare buffer
pointer as __const.
* string/tester.c (main): Test stpncpy.
* sysdeps/generic/stpncpy.c (__stpncpy): Fix so it works without
segfault when called with an N that is not a multiple of four and
src[N-1]=='\0'.
* misc/syslog.c (LogType): New variable.
(openlog): If connect() with SOCK_DGRAM fails with EPROTOTYPE,
try again with SOCK_STREAM (the Linux syslogd uses a socket of the
latter type).
(vsyslog): When LogType==SOCK_STREAM, also send ASCII NUL
terminator as a record-delimiter. If __send(LogFile) fails,
call closelog() so logfile gets re-opened next time.
Wed Aug 7 15:15:14 1996 Ulrich Drepper <drepper@cygnus.com>
* elf/dl-open (_dl_open): Add cast to avoid warning.
* manual/memory.texi: Improve some examples to give readers better
advice: Use `stpcpy' instead of `strcat' if possible.
* manual/string.texi: Document `strtok_r' and `strtok'.
* sunrpc/Makefile: Move `+gccwarn' definition before inclusion
of Makeconfig.
[$(cross-compiling)=no]: Change test before making librpcsvc
to this from $(cross-compile).
Reported by Andreas Schwab.
Tue Aug 6 14:27:11 1996 Ulrich Drepper <drepper@cygnus.com>
* elf/Makefile (routines): Move dl-sysdep to here...
(rtld-routines): ...from here. This should make static linking
work again.
* locale/setlocale.c: Add local variable `lock' and add code to
`setlocale' to avoid simultaneous changing of global data.
* catgets/catgets.c (catopen): Use `__strdup' instead of `strdup'.
* catgets/open_catalog (__open_catalog): Use `__stpcpy', `__open',
`__fstat', `__read', `__mmap', `__munmap' and `__close' instead
of unprotected names.

undocumented test addition in _dl_map_object.
Support ET_EXEC versions of ld.so, for debugging at least:
* elf/dl-load.c (_dl_map_object): Add_name_to_object could get

Update.
Thu Aug 8 01:41:43 1996 Ulrich Drepper <drepper@cygnus.com>
* elf/Makefile: Undo change of Tue Aug 6 14:27:11 1996.
* elf/dl-support: Add definition of `_dl_sysdep_read_whole_file'.
Thu Aug 8 01:15:59 1996 Ulrich Drepper <drepper@cygnus.com>
* sysdeps/i386/fpu_control.h (_FPU_DEFAULT, _FPU_IEEE): Set
to 0x137f to allow long double operations.
Sun Aug 4 13:12:05 1996 Richard Henderson <rth@tamu.edu>
Bug Fixes:
* nss/nsswitch.c (_res): Remove redundant variable definition.
The real one is in resolve/res_init.c, and having both prevents
using -fno-common when building the shared library.
* sunrpc/rpc_prot.c (_null_auth): Same. Original is in rpc_common.c.
* sysdeps/unix/sysv/linux/alpha/brk.S: When PIC, define __curbrk as
a .bss object not a COMMON symbol.
* sysdeps/alpha/bsd-_setjmp.S, sysdeps/alpha/bsd-setjmp.S: Must load
$gp before referencing __sigsetjmp symbol. Retain LITUSE for same.
Optimizations:
* sysdeps/alpha/strlen.S: Rearrange first-word setup and thense the
main loop for better dual-issue on EV5. Rearrange binary search to
pipeline better and trim one instruction.
Cosmetic Changes:
* time/localtime.c (localtime_r): Move lock declaration back next to
the comment where it was before the 960724 change.
* INSTALL, manual/maint.texi: alpha-gnu-linux -> alpha-ANYTHING-linux.
The second word is supposed to be the hardware manufacturer.
* sysdeps/alpha/_mcount.S: Retain LITUSE for __mcount.
* sysdeps/alpha/setjmp.S: Retain LITUSE for __sigsetjmp_aux.
* sysdeps/alpha/divrem.h: More local labels, retain LITUSE for _mcount.
* sysdeps/alpha/alphaev5/add_n.S, sysdeps/alpha/alphaev5/lshift.S,
sysdeps/alpha/alphaev5/rshift.S, sysdeps/alpha/alphaev5/sub_n.S:
Same cleanups as with EV4 GMP stuff.
Tue Jul 25 03:30:56 1996 Richard Henderson <rth@tamu.edu>
* sysdeps/unix/sysv/linux/Makefile [misc] (sysdep_routines): Add clone.

`unsigned long'.
* misc/sys/select.h: Declare fd_mask as alias of __fd_mask.
Sat Aug 3 16:20:02 1996 David Mosberger-Tang <davidm@azstarnet.com>
* sysdeps/unix/sysv/linux/alpha/ioperm.c (platform): Add entry for
Mikasa.
* socket/sys/socket.h (send, __send, sendto): Declare buffer
pointer as __const.
* string/tester.c (main): Test stpncpy.
* sysdeps/generic/stpncpy.c (__stpncpy): Fix so it works without
segfault when called with an N that is not a multiple of four and
src[N-1]=='\0'.
* misc/syslog.c (LogType): New variable.
(openlog): If connect() with SOCK_DGRAM fails with EPROTOTYPE,
try again with SOCK_STREAM (the Linux syslogd uses a socket of the
latter type).
(vsyslog): When LogType==SOCK_STREAM, also send ASCII NUL
terminator as a record-delimiter. If __send(LogFile) fails,
call closelog() so logfile gets re-opened next time.
Wed Aug 7 15:15:14 1996 Ulrich Drepper <drepper@cygnus.com>
* elf/dl-open (_dl_open): Add cast to avoid warning.
* manual/memory.texi: Improve some examples to give readers better
advice: Use `stpcpy' instead of `strcat' if possible.
* manual/string.texi: Document `strtok_r' and `strtok'.
* sunrpc/Makefile: Move `+gccwarn' definition before inclusion
of Makeconfig.
[$(cross-compiling)=no]: Change test before making librpcsvc
to this from $(cross-compile).
Reported by Andreas Schwab.
Tue Aug 6 14:27:11 1996 Ulrich Drepper <drepper@cygnus.com>
* elf/Makefile (routines): Move dl-sysdep to here...
(rtld-routines): ...from here. This should make static linking
work again.
* locale/setlocale.c: Add local variable `lock' and add code to
`setlocale' to avoid simultaneous changing of global data.
* catgets/catgets.c (catopen): Use `__strdup' instead of `strdup'.
* catgets/open_catalog (__open_catalog): Use `__stpcpy', `__open',
`__fstat', `__read', `__mmap', `__munmap' and `__close' instead
of unprotected names.

undocumented test addition in _dl_map_object.
Support ET_EXEC versions of ld.so, for debugging at least:
* elf/dl-load.c (_dl_map_object): Add_name_to_object could get
called despite the DT_SONAME != NULL test, segfaulting. Simplify
the code here as well.

Sparc 32 merge:
* elf/dl-runtime.c (ELF_FIXUP_RETURN_VALUE): Provide default value.

anything anymore, and what it did do is done somewhere else.
* sysdeps/sparc/configure: Likewise.
