Update.
1997-03-21 20:55 Ulrich Drepper <drepper@cygnus.com> * sysdeps/generic/machine-gmon.h: Update copyright. * sysdeps/i386/Makefile [$(subdir)=gmon] (sysdep_routines): Add i386-mcount. * sysdeps/i386/dl-machine.h [PROF] (_dl_runtime_resolve): Don't use regparam mechanism for call of `fixup' call. * sysdeps/i386/Dist: New file. * sysdeps/i386/i386-mcount.S: New file. `mcount' entry point. * sysdeps/i386/machine-gmon.h: New file. i386 specific version of gmon definitions. 1997-03-20 13:39 Andreas Jaeger <aj@arthur.pfalz.de> * stdlib/tst-strtol.c (main): Save the value of errno since printf may modify it, use the saved errno everywhere. * stdlib/tst-strtod.c (main): Likewise. 1997-03-21 05:54 Ulrich Drepper <drepper@cygnus.com> * posix/glob.c (glob): Fix completely broken handling of GLOB_BRACE and partly broken handling of GLOB_TILDE. Reported by Dennis Henriksen <opus@flamingo.osrl.dk>. 1997-03-20 20:22 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/readv.c: Don't emulate readv with small UIO_FASTIOV value by multiple readv calls since we need atomicity. * sysdeps/unix/sysv/linux/writev.c: Likewise. Reported by Matthis Urlichs. 1997-03-20 04:34 Roland McGrath <roland@baalperazim.frob.com> * sysdeps/unix/sysv/linux/i386/sysdep.S (CALL_MCOUNT): Clear this macro so ENTRY(__syscall_error) doesn't insert a call to _mcount, which clobbers %eax. * Makeconfig [$(elf)=yes] (+prector, +postctor): New variables for crtbegin.o/crtend.o, using gcc to find them. (+link): Use them. 1997-03-20 00:06 Richard Henderson <rth@tamu.edu> * gmon/sys/gmon.h: Revert the bulk of the 960930 changes, as they affect the alignment, and therefore the end padding of the structs. Reported by David Mosberger <davidm@azstarnet.com>. * gmon.c: Declare the variables with aligned tags to compensate. Use __writev instead of write for the I/O. * misc/sys/uio.h: Declare __writev and __readv. * sysdeps/posix/readv.c: Rename and alias readv to __readv. * sysdeps/posix/writev.c: Likewise for writev. * sysdeps/stub/readv.c: Likewise. * sysdeps/stub/writev.c: Likewise. * sysdeps/unix/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/readv.c: Likewise. * sysdeps/unix/sysv/linux/writev.c: Likewise. * stdlib/testdiv.c: Exit with error status when we have an error. * sysdeps/alpha/div.S: Initialize `quotient' and `mask'. * sysdeps/alpha/ldiv.S: Likewise. * sysdeps/unix/sysv/linux/alpha/ioperm.c: Include ctype.h for isdigit. 1997-03-20 14:51 Ulrich Drepper <drepper@cygnus.com> * nis/nis_file.c: Unify error handling. 1997-03-19 18:36 Thorsten Kukuk <kukuk@vt.uni-paderborn.de> * nis/nis_file.c (writeColdStartFile): Fix typo. * nis/nis_free.c (nis_free_endpoints): Use unsigned int. * nis/nis_free.c (nis_free_servers): Likewise. * nis/rpcsvc/nislib.h: Likewise. * sunrpc/rpc/netdb.h: Add setrpcent and endrpcent prototypes.
