        [USE_PROCFS] (pollv): Make this a pointer, not an array; make static.
        (rebuild_pollv): Dynamically allocate the vector.
        * defs.h (tcbtab): Update decls.

        __WNOTHREAD and __WALL.

        * strace.c (trace) [LINUX]: Only check errno if wait4 actually fails,
        so we don't repeat a wait and thus drop a status.  Fixes RH#62591.

2002-12-15  Roland McGrath  <roland@redhat.com>

        * process.c (setarg) [POWERPC]: Support it.

        * util.c [POWERPC] (LOOP): Fix value, now 0x48000000 (0: b 0b).

        * linux/sparc/syscallent.h: Likewise.
        * linux/hppa/syscallent.h: Likewise.

        * syscall.c (syscall_enter) [LINUX && POWERPC]: Define PT_ORIG_R3 if
        not defined, since <asm/ptrace.h> defines it only #ifdef __KERNEL__.
        * process.c: Likewise.

        * desc.c (sys_osf_select): Add missing return type.

        * syscall.c (trace_syscall): Use strerror, not sys_errlist/sys_nerr.

        * linux/ia64/syscallent.h: Remove macros for sys_delete_module,

        (trace_syscall): Fix return without value.

        * linux/syscallent.h: Update table with names of new syscalls

        * linux/syscall.h: Declare them.
        * linux/syscallent.h: Update the table for these.

        * linux/syscall.h: Add sys_* decls for new syscalls getpmsg, putpmsg,
        readahead, sendfile64, setxattr, fsetxattr, getxattr, fgetxattr, int
        listxattr, flistxattr, removexattr, fremovexattr, sched_setaffinity,
        sched_getaffinity, futex.

        * linux/ia64/syscallent.h: Define ia32 syscall numbers (originally
        by Don Dugger, with my refinements).

        * linux/ia64/ioctlent.h: Regenerate and manually merge conflicting
        ioctls (TCGETS & SNDCTL_TMR_TIMEBASE, etc.).

        * linux/ia64/Makefile.in (ioctldefs.h ioctls.h): Update for
        new ioctlent.h generation scheme.

        * linux/syscall.h (sys_clone2): Declare.
        [IA64] Define ia32 socket, ipc, and extra syscall numbers.

        * linux/ioctlent.sh (regexp): Also handle <asm/ioctls.h> so we
        don't miss the tty ioctls (unfortunately, some of the sound timer
        ioctls are in conflict with them!).

        * util.c (setbpt) [IA64]: Add ia32 support (by Don Dugger).
        (clrbpt) [IA64]: Ditto.

        * syscall.c (internal_syscall): Handle SYS_clone2, SYS32_wait4,
        and SYS32_exit.

        [IA64]: Declare "ia32" variable.

        directly instead.

2001-10-01  David Mosberger  <davidm@hpl.hp.com>

        * signal.c (parse_sigset_t): New function.

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>

  * linux/ioctlent.sh: change regexps so we catch sound ioctls as well in

  * config.{guess,sub}: updated

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

    it was just passing the sigmask (ucp->uc_sigmask).

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

  * util.c: Don't run off the end of valid memory in umovestr when
    USE_PROCFS.  Important for FREEBSD systems (which seem to have an
    unmapped page just after the args/env area).

2001-04-18  John Hughes <john@Calva.COM>

  * configure.in: test for sys/nscsys.h, the non-stop clusters includes.
  * process.c: handle rfork{1,all} and rexecve calls on non-stop clusters.
  * syscall.c: treat rfork{1,all} and fork{1,all} as fork like calls.
    Treat rexecve as an exec.
  * system.c: decode arguments to ssisys call on nsc systems.
  * svr4/dummy.h, svr4/syscall.h: now we handle rfork{1,all}, ssisys and

  * linux/sparc/syscall.h: Update used sparc-linux syscalls.
  * linux/sparc/syscallent.h: Match 2.2.9 system calls.
  * file.c: sparc-linux asm/stat.h uses dev_t etc. types,
    so it needs strace's own copy of the stat structure.
  * util.c: Make it compile on sparc-linux.
  * strace.c: Fix strace -f and -ff operation on sparc-linux.

    + correct ARM/POWERPC architecture defines in acconfig.h
  * Merge in patches from Morten Welinder <terra@diku.dk>
    + add some autoconf-tests for includefiles
    + handle solaris version of sigcontext struct (actually I hacked this
      up again, but the idea is his :)

    to use reasonably recent kernel headers to compile strace now.
  * Change references to LINUX into linux in file.c
  * Fix include for LDT in mem.c

Thu Apr 15 22:28:15 CEST 1999 Wichert Akkerman <wakkerma@debian.org>

        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>

        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.

        * 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.

        * 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.

        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.
