* malloc/malloc.c (_malloc_internal): Performance fix. Move
if statement out of loop.
* stdio/_itoa.c, stdio/_itoa.h: Complete rewrite. Much faster
implementation using GMP functions. Contributed by
Torbjorn Granlund and Ulrich Drepper.
* stdio/test_rdwr.c: Include <errno.h>.
* sysdeps/i386/i586/Implies: New file.
New highly optimized string functions for i[345]86.
* sysdeps/i386/memchr.S, sysdeps/i386/memcmp.S: New files.
* sysdeps/i386/stpcpy.S, sysdeps/i386/stpncpy.S: New files.
* sysdeps/i386/strchr.S, sysdeps/i386/strcspn.S: New files.
* sysdeps/i386/strpbrk.S, sysdeps/i386/strrchr.S: New files.
* sysdeps/i386/strspn.S, sysdeps/i386/i486/strcat.S: New files.
* sysdeps/i386/i486/strlen.S, sysdeps/i386/i586/strchr.S: New files.
* sysdeps/i386/i586/strlen.S: New file.
* sysdeps/i386/memchr.c: Removed. There is now an assembler version.
* sysdeps/i386/i586/memcopy.h (WORD_COPY_BWD): Parameters did
not correspond to used values.
* sysdeps/unix/sysv/linux/nfs/nfs.h: New file. Simply a wrapper
around a kernel header file.
* sysdeps/unix/sysv/linux/Dist: Add it.
* sysdeps/unix/sysv/linux/Makefile [$(subdir)=sunrpc] (headers):
Likewise.
* sysdeps/unix/sysv/linux/local_lim.h: Rewrite. Instead of
defining ourself we use a kernel header file.
* sysdeps/unix/sysv/linux/i386/sysdep.h (DO_CALL): Optimize system
call handler for i586.
* sysdeps/unix/sysv/linux/sys/param.h: Add copyright and clean up.
