From a9ddb79305d6346fdf2bcb1772213987d53c0bc5 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Mon, 20 Jul 1998 17:25:48 +0000 Subject: Update. 1998-07-20 17:09 Ulrich Drepper * shlib-versions: Remove definition for libSegFault. * memory.texi: Comment out the relocating allocator description. * manual/signal.texi: Remove reference to relocating allocator. * manual/top-menu.texi: Regenerated. * posix/fnmatch.c: Implement [: :] and change to recognize ^ as negation only when not _POSIXLY_CORRECT. * sysdeps/generic/glob.c: Add several optimizations. * posix/glob.h: Undefine __PMT to prevent warnings. Reported by Roland McGrath. * posix/regex.c: Define namespace macros only for _LIBC. * sysdeps/arm/dl-machine.h: Fix typo. * sysdeps/unix/sysv/sysv4/solaris2/sigpending.c: New file. * sysdeps/unix/sysv/sysv4/solaris2/sigstack.c: New file. * sysdeps/unix/sysv/sysv4/solaris2/sigwaitinfo.c: New file. * sysdeps/unix/sysv/sysv4/solaris2/syscalls.list: Add sigaltstack, sigpending, sigqueue, and sigtimedwait. * sysdeps/unix/sysv/sysv4/solaris2/sparc/sparc32/syscall.S: New file. * timezone/leapseconds: Update from tzdata1998f. 1998-07-18 Mark Kettenis * stdio/stdio.h [__USE_GNU]: Add prototype for fputs_unlocked. * stdio/Versions [GLIBC_2.1]: Add fputs_unlocked. * libio/stdio.h: Fix typo. 1998-07-19 Roland McGrath * sysdeps/mach/hurd/dl-sysdep.c (_dl_sysdep_start): #if 0 out the magic memobj port arg parsing stuff. Fix it someday when we are ready to really use it. (_dl_sysdep_output): New function, modified from _dl_sysdep_error. (_dl_sysdep_error, _dl_sysdep_message, _dl_sysdep_fatal): Removed. 1998-07-19 Roland McGrath * stdio/fputs.c: Add fputs_unlocked as weak alias for fputs. 1998-07-19 Roland McGrath * sysdeps/posix/sigsuspend.c: Define __sigsuspend with sigsuspend as a weak alias. * sysdeps/mach/hurd/sigsuspend.c: Likewise. * sysdeps/generic/sigsuspend.c: Likewise. 1998-07-19 Roland McGrath * sysdeps/mach/hurd/i386/sigcontextinfo.h: New file. 1998-07-19 Andreas Schwab * Makerules (map-file): Don't use $(wildcard) to find the generated version script, instead look in $(version-maps). ($(common-objpfx)libc.so): Only depend on libc.map if versioning is used. * extra-lib.mk ($(objpfx)$(lib).so): Only depend on version script if versioning is used. Don't use $(wildcard) to find the generated version script, instead look in $(verson-maps). 1998-07-17 Andreas Schwab * sysdeps/generic/segfault.c: Rename GET_EIP to GET_PC. Remove unused function handle. * sysdeps/generic/sigcontextinfo.h: Rename GET_EIP to GET_PC. * sysdeps/unix/sysv/linux/i386/sigcontextinfo.h: Likewise. * debug/catchsegv.sh: Fix argument processing, quoting and various typos. Put the crash info always in the current directory. Find program in $PATH if it contains no directory component. * Makerules (install-lib.so-versioned, install-lib.so-unversioned): New variables. (install-lib-nosubdir): Depend on unversioned libs in slibdir, not libdir. 1998-07-19 Andreas Schwab * Make-dist (+tsrcs): Remove references to %-map variables and *.map files. Add Versions in subdirs. * Makerules (distinfo-vars): Don't write out %-map variables. 1998-07-20 13:55 Ulrich Drepper * inet/protocols/rwhod.h: Remove definition of _PATH_RWHODIR. Include instead. * sysdeps/generic/paths.h: Define _PATH_RWHODIR. * sysdeps/unix/sysv/linux/paths.h: Likewise. Reported by Dale Scheetz . 1998-07-17 21:44 Ulrich Drepper * catgets/open_catalog.c: Strictly check whether catalog file is larger enough for the data.
