1997-02-27 05:12 Ulrich Drepper <drepper@cygnus.com>
* manual/Makefile: Add rules to run and distribute xtract-typefun.
* manual/xtract-typefun.awk: New file. Script to extract function,
variable, macro anchor to put into the `dir' file.
* manual/signal.texi: Document difference between SysV and BSD
signal(3) function and add documentation for sysv_signal.
* sysdeps/libm-i387/e_acoshl.c: Clear upper half of word containing
exponent before comparing.
1997-02-27 01:13 Ulrich Drepper <drepper@cygnus.com>
* sysdeps/generic/netinet/in.h (htonl, htons, ntohl, ntohs): Change
prototypes to use types with explicit width. `unsigned long' is
different on 64 bit systems.
* sysdeps/unix/sysv/linux/netinet/in.h: Likewise.
* sysdeps/generic/htonl.c: Likewise.
* sysdeps/generic/htons.c: Likewise.
* sysdeps/generic/ntohl.c: Likewise.
* sysdeps/generic/ntohs.c: Likewise.
Suggested by a sun <asun@zoology.washington.edu>.
1997-02-26 08:30 Andreas Jaeger <aj@arthur.pfalz.de>
* math/math.h: Include <__math.h> if __NO_MATH_INLINES is not
defined and we want optimization.
1997-02-27 01:13 Ulrich Drepper <drepper@cygnus.com>
* sysdeps/generic/netinet/in.h (htonl, htons, ntohl, ntohs): Change
prototypes to use types with explicit width. `unsigned long' is
different on 64 bit systems.
Suggested by a sun <asun@zoology.washington.edu>.
1997-02-02 19:53 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* misc/getpass.c: Don't disable canonical input.
Reverted patch of Mon Jan 6 01:35:29 1997.
1996-12-14 22:07 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* libio/libioP.h (_IO_finish_t): Take additional parameter, to
match the hidden __in_chrg parameter of the destructor.
(_IO_FINISH): Pass zero for it.
* libio/genops.c (_IO_default_finish): Add second parameter, which
is ignored.
* libio/memstream.c (_IO_mem_finish): Likewise.
* libio/fileops.c (_IO_mem_finish): Likewise.
* libio/strops.c (_IO_str_finish): Likewise. All callers changed.

* time/Makefile: Avoid using patterns in dependencies.
1997-02-26 00:56 Miguel de Icaza <miguel@nuclecu.unam.mx>
* elf/rtld.c: Make _dl_start static. Otherwise the linker on the
SPARC will convert the call _dl_start into a call into the PLT.
* elf/rtld.c (_dl_start): On the SPARC we need to adjust the value
of arg to make it point to the actual values.
* sysdeps/sparc/elf/DEFS.h: New ELF specific version.
* sysdeps/sparc/Dist: Mention sysdeps/sparc/elf/DEFS.h.
* sysdeps/sparc/bsd-_setjmp.S, sysdeps/sparc/bsd-setjmp.S: Make
them PIC aware.
* sysdeps/sparc/dl-machine.h (elf_machine_load_address):
Implemented.
(elf_machine_rela): Make it compile; fix existing relocation
types; add unhandled relocation types.
(ELF_ADJUST_ARG): Get pointer to arguments at program startup.
(RTLD_START): Initial implementation, not yet finished.
* sysdeps/sparc/elf/start.S: Fix.
* sysdeps/sparc/fpu_control.h: Remove duplicate declaration of
__setfpucw.
* sysdeps/sparc/divrem.m4: Make compilable under Linux.
* sysdeps/sparc/rem.S, sysdeps/sparc/sdiv.S, sysdeps/sparc/udiv.S,
sysdeps/sparc/urem.S : Regenerated.
* sysdeps/sparc/setjmp.S: Make it PIC aware.
* sysdeps/unix/sysv/linux/sparc/__sigtrampoline.S: Define
__ASSEMBLY__ before using kernel header.
* sysdeps/unix/sysv/linux/sparc/Makefile: Use -mv8 flag to compile
rtld.c.
* sysdeps/unix/sysv/linux/sparc/brk.c: Implement.
* sysdeps/unix/sysv/linux/sparc/profil-counter.h: Remove code
to handle old signals.
* sysdeps/unix/sysv/linux/sparc/sigaction.c: Implements sigaction
for all Linux/SPARC kernels.
* sysdeps/unix/sysv/linux/sparc/syscall.S: Add code to store
errno using __errno_location.
* sysdeps/unix/sysv/linux/sparc/sysdep.h: Add various handler
macros for assembler sources.
* sysdeps/unix/sysv/linux/sparc/errno.c: Define errno.
1997-02-25 16:02 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* elf/rtld.c (dl_main): Remove dead code that is never executed.
Rename local variable l to main_map where it is used to point to
the load_map for the executable.
1997-02-25 15:03 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* elf/dl-version.c (_dl_check_all_versions): Ignore libraries that
could not be found.
1997-02-24 23:18 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* Makerules: Generate implicit object suffix rules automagically.
(o-iterator): Move before first use.
* Makeconfig (all-object-suffixes): Add .bo suffix.
1997-02-25 15:11 Ulrich Drepper <drepper@cygnus.com>
* sysdeps/libm-i387/e_acoshf.S (__ieee754_acoshf): Test correct
word on stack for overflow.
C++. Use __exception instead.
