        r8 (eax).  Handle TCB_WAITEXECVE.
        (syscall_fixup): Handle ia64.
        (syscall_enter): Fix argument fetching for ia64.

        * strace.c [IA64 && LINUX]: Include <asm/ptrace_offsets.h>.

        * process.c (tcp): New function.
        (change_syscall): Add support for ia64 linux.
        (sys_execve): Turn on TCB_WAITEXECVE for ia64 linux.

        * desc.c (getlk): Cast l_len to "long long" to avoid warnings when
        type is narrower.
        * resource.c (sprintrlim64): Ditto.

        * defs.h (TCB_WAITEXECVE) [IA64]: Define.

        * signal.c (parse_sigset_t): New function.

        * syscall.c (syscall_enter): Use PT_RBS_END instead of deprecated
        PT_AR_BSP.  Pick up arguments starting with out0, which is not
        always the same as r32 (e.g., consider inlined syscalls).

2001-09-28   John Hughes <john@Calva.COM>

  * process.c: FreeBSD-CURRENT no longer has PT_READ_U, and anyway we
    were showing it as PT_WRITE_U!  Fix from Maxime Henrion.

2001-09-18   John Hughes <john@Calva.COM>

  * net.c: fix display of sockaddr structures, sometimes too many "}",
    sometimes too few.  Fix suggested by Richard Kettlewell.

2001-08-19   Wichert Akkerman <wakkerma@debian.org>

2001-05-15  John Hughes <john@Calva.COM>

Thu May 23 01:04:43 1996  J. Richard Sladkey  <jrs@world.std.com>

        * aclocal.m4 (AC_DECL_SYS_ERRLIST): Try looking in stdio.h
        as well since that's where glibc declares it.  Go figure.
        * signal.c (sys_sigreturn) [ALPHA]: Use sigcontext
        instead of sigcontext_struct since glibc v5+ apparently
        plays games with the native OS namespace.
        From David Mosberger-Tang <davidm@AZStarNet.com>.

Mon May 20 23:17:14 1996  J. Richard Sladkey  <jrs@world.std.com>

        * configure.in: (AC_CHECK_{HEADERS,FUNCS}): Add checks for
        sys/filio.h and sys/stream.h and remove check for poll.
        * desc.c (decode_select, sys_select, sys_oldselect) [LINUX]:
        Handle old and new styles of argument passing for select on Linux.
        * ioctl.c, stream.c: Conditionalize stream code on presence of
        sys/stream.h instead of poll because glibc implements poll but
        not the rest of the stream interface.
        * signal.c [LINUX]: Standardize on the name sigcontext_struct.
        (sys_sigprocmask) [ALPHA]: Handle OSF flavor which is more like
        sigsetmask.
        * term.c (term_ioctl): Use _VMIN, if present, for TC{G,S}ETA*.
        * util.c (umoven, umovestr): Move data in long-sized chunks
        at a time, instead of hard coding it to be 4.

        * signal.c [HAVE_ASM_SIGCONTEXT_H]: Conditionally include
        asm/sigcontext.h to define sigcontext_struct and don't define it
        locally if the header is present.

        * syscall.c (nerrnos{0,2}): Correct size computation.

        * Makefile.in: Remove dependencies and rules relating to files
        normally found in the os directory.  Because of the new scheme we
        don't know precisely where they come from.  Sigh.
        * signalent.sh: Make it work for sunos4, linux, and svr4.
        * {sunos4,linux{,/alpha},svr4}/Makefile.in: Make rules correspond
        to traditional make syntax.  Add signalent.h to files which can
        unconditionally be rebuilt.  Prevent signalent.h from being
        unconditionally being rebuilt since it's customized.
        * {sunos4,linux{,/alpha},svr4}/{ioctlent,errnoent,signalent}.h:
        Use versions built by {ioctlent,errnoent,signaltent}.sh.
        * sunos4/ioctlent.sh: Work around sprintf troubles with SunOS

        * defs.h, ioctlsort.c: Make ioctl code member unsigned.
        * ioctl.c, ioctlsort.c (compare): Perform explicit checking
        for less, greater, and equal since subtraction on two's
        complement numbers isn't an order relation (it isn't transitive)!
        * linux/Makefile.in: Add rules for the signalent.h file.
        * linux/alpha/Makefile.in: New file.

        Suggested by Tom Dyas <tdyas@eden.rutgers.edu>.

        * util.c (upeek): Handle case where ptrace returns a long
        and sizeof(long) != sizeof(int).
        From Richard Henderson <richard@twiddle.tamu.edu>

Fri May 17 21:03:36 1996  J. Richard Sladkey  <jrs@world.std.com>

        osf_statfs and osf_fstatfs for the alpha.  Make damn sure
        major and minor results are suitable for passing to printf.
        * signal.c, syscall.c: Support the alpha.
        * process.c: Add alpha user offsets.
        * most files: Use %l? for printf arguments since
        most are now longs for the alpha.
        * linux/alpha/{errnoent.h,ioctlent.{h,sh},syscallent.h}:
        New for the alpha.
        From Thomas Bogendoerfer <tsbogend@bigbug.franken.de>.
