1997-07-22 01:35 Ulrich Drepper <drepper@cygnus.com> * Makerules (+make-deps): Use $(CFLAGS) in run of $(+mkdep) so that optimizing is also selected for dependency generation. * configure.in: Add machine description for TI c[34]x. * inet/Makefile (routines): Remove ntohl and ntohs. * inet/netinet/in.h: Use optimized version of hton? and ntoh? for little endian machines. * sysdeps/alpha/ntohl.s: Removed. * sysdeps/alpha/ntohs.s: Removed. * sysdeps/generic/ntohl.c: Removed. * sysdeps/generic/ntohs.c: Removed. * sysdeps/generic/htonl.c: Add aliases for ntohl. * sysdeps/vax/htonl.s: Likewise. * sysdeps/generic/htons.c: Add aliases for ntohs. * sysdeps/vax/htons.s: Likewise. * sysdeps/vax/ntohl.s: Removed. * sysdeps/vax/ntohs.s: Removed. * sysdeps/generic/bits/htontoh.h: New file. * sysdeps/i386/htonl.S: New file. * sysdeps/i386/htons.S: New file. * sysdeps/i386/i486/htonl.S: New file. * sysdeps/i386/fpu/bits/mathinline.h: Correct and optimized compare macros. * sysdeps/mips/dl-machine.h: Remove mips64 dependent parts. * sysdeps/mips/mips64/dl-machine.h: New file. * sysdeps/unix/sysv/linux/Makefile (sysdep_headers): Don't install syscall-list.h. 1997-07-12 Andreas Jaeger <aj@arthur.rhein-neckar.de> * libc.map: Add missing symbol _obstack. 1997-07-14 08:22 H.J. Lu <hjl@gnu.ai.mit.edu> * sysdeps/mips/rtld-parms: New. * sysdeps/unix/sysv/linux/mips/lxstat.h: Moved to * sysdeps/unix/sysv/linux/mips/lxstat.c: ...this. * sysdeps/unix/sysv/linux/mips/sgidef.h: Moved to * sysdeps/unix/sysv/linux/mips/sgidefs.h: ...this. * sysdeps/generic/dl-sysdep.c (_start): Change to ENTRY_POINT. 1997-07-17 08:39 H.J.
