Kernel header <asm/signal.h> cannot be included from regular code
because it conflicts with libc headers, but SA_RESTORER is needed in
signal.c, so SA_RESTORER value is forwarded from <asm/signal.h> to
config.h using a configure check.
* configure.ac (ASM_SA_RESTORER): Define if SA_RESTORER is defined
in <asm/signal.h>.
* configure.ac (AC_CHECK_TYPES): Add struct flock64.
* desc.c (HAVE_F_SETLK64, HAVE_F_SETLKW64, HAVE_F_GETLK64): New macros.
[!HAVE_STRUCT_FLOCK64] (struct flock64): Define.
(printflock64): Define only if referenced by other code.
(sys_fcntl): Handle F_FREESP64, F_SETLK64, F_SETLKW64, and F_GETLK64 iff
these constants are defined and differ from their non-64bit versions.
* configure.ac (AC_CHECK_DECLS): Add PTRACE_PEEKUSER and
PTRACE_POKEUSER.
* defs.h: Define PTRACE_PEEKUSER and PTRACE_POKEUSER only if
they are not provided by <sys/ptrace.h>.

SIGEV_THREAD_ID decoding requires access to an internal member of
struct sigevent. There seems to be no portable way to do it besides
adding a configure check.
* configure.ac (AC_CHECK_MEMBERS): Check for
struct sigevent._sigev_un._pad and struct sigevent.__pad.
* time.c (printsigevent): Use an appropriate struct sigevent member
to print thread id.
Reported by John Spencer.
Most of the code already uses long long types unconditionally.
* configure.ac: Remove the check for long long.
* file.c (printstat64): Remove HAVE_LONG_LONG checks, use %llu format
string unconditionally.
This change incorporates a partial copy instead
of using external libaio.h.
Why?
Because we want to properly decode 32-bit aio calls
by 64-bit strace. For that, we need more definitions than
libaio.h provides.
(These defs are not done yet, but will eventually be done).
Keeping our local 32-bit compat defs in sync with libaio.h
_without seeing libaio structs_ is hard/more bug prone.
A smaller benefit is that we don't need libaio installed.

Take #2 on mainlining strace support for ARC (last one was 4.6 based back
in March 2011), see
http://sourceforge.net/p/strace/mailman/message/27210168/
The syscall ABI is asm-generic/unistd.h based (so no legacy syscalls),
hence very similar to metag port.

We were using uname to determine if userspace was 32 or 64bit.
This fails when we have a 64bit kernel and a 32bit userspace.

Building with automake-1.13 throws an error:

Add support for Imagination Technologies Meta architecture (the
architecture/ABI is usually referred to as metag in code). The Meta
Linux kernel port is in the process of being upstreamed for v3.9 so it
uses generic system call numbers.
sys_lookup_dcookie writes a filename to buffer argument, so I've set
TF flag.
nfsservctl appears to be set to sys_ni_syscall in asm-generic/unistd.h
so I've left it blank.
truncate64/ftruncate64/pread64/pwrite64/readahead have unaligned 64bit
args which are packed tightly on metag, so less arguments on metag.
fchdir/llseek takes a file descriptor so s/TF/TD/
sync_file_range has 2 64bit args so uses 6 args, so s/4/6/
timerfd_create/msgget/msgctl/msgrcv/semget/segtimedop/semop/shmget/
shmctl/shmat/shmdt/recvmsg/migrate_pages have different number of args.
oldgetrlimit is just getrlimit for metag.
add TM flag to various memory syscalls.
metag doesn't directly use sys_mmap_pgoff for mmap2.
prlimit64/process_vm_readv/process_vm_writev take a pid so add TP flag.
fanotify_init doesn't appear to take a file descriptor so remove TD.
Add kcmp syscall.

X32 support is added to Linux kernel 3.4. In a nutshell, x32 is x86-64 with
32bit pointers. At system call level, x32 is also identical to x86-64,
as shown by many changes like "defined(X86_64) || defined(X32)". The
main differerence bewteen x32 and x86-64 is off_t in x32 is long long
instead of long.
This patch adds x32 support to strace. Tested on Linux/x32.

The long long endian detection code does an AC_TRY_RUN() and since that
doesn't work when cross-compiling, it sets a fallback value. However,
rather than do any sort of default endian detection, the code simply
sets it to "no". This probably breaks most little endian systems out
there when cross-compiling for them. It certainly breaks Blackfin
systems. So use the common endian detection code provided by autoconf
and key off of that when cross-compiling.
* configure.ac: Call AC_C_BIGENDIAN.
* m4/long_long.m4 (AC_LITTLE_ENDIAN_LONG_LONG): Set cross-compiling
logic based on ac_cv_c_bigendian.
