pc_LDADD, times_LDADD): Add $(LDADD).
* tests/.gitignore: Add libtests.a.

tests: enable strace-k.test only for --with-libunwind configurations

Also, since -k option does not support multiple personalities,
add strace-k.test to XFAIL_TESTS when running mpers tests.

* tests/Makefile.am (MPERS_NAME, LIBUNWIND_TESTS, XFAIL_TESTS_,
XFAIL_TESTS_m32, XFAIL_TESTS_mx32, XFAIL_TESTS): New variables.
[USE_LIBUNWIND] (LIBUNWIND_TESTS): Add strace-k.test.

Move gcc compat macros to gcc_compat.h

(GNUC_PREREQ, ATTRIBUTE_NORETURN, ATTRIBUTE_FORMAT,
ATTRIBUTE_ALIGNED, ATTRIBUTE_PACKED, ATTRIBUTE_MALLOC,
ATTRIBUTE_NOINLINE, ATTRIBUTE_ALLOC_SIZE): Move ...

* test/Makefile (PROGS): Remove fork and vfork.

Check how strace -f follows fork and vfork syscalls.

Set SYSCALL_NEVER_FAILS flag for getpid, getppid and gettid syscall

* linux/*/syscallent*.h (getpid, getppid, gettid): Set NF flag.

Set SYSCALL_NEVER_FAILS flag for umask syscall

Linux kernel always ANDs umask argument with 0700 and therefore
this syscall never fails.

* linux/*/syscallent*.h (umask): Set NF flag.

alpha, ia64, mips, nios2, powerpc, sparc: always check for syscall error

On architectures that use dedicated registers to report syscall errors,
check for syscall error condition regardless of SYSCALL_NEVER_FAILS flag
in the syscall entry.  On architectures that use negated errno
semantics, there is no way to distinguish a syscall error from a valid
return code that looks like a syscall error, and the check for
SYSCALL_NEVER_FAILS flag remains the only way to tell one case
from another.

* linux/alpha/get_error.c (get_error): Ignore check_errno.
* linux/ia64/get_error.c: Likewise.
* linux/mips/get_error.c: Likewise.

* linux/powerpc/get_error.c: Likewise.

Handle unlikely errors from personality syscall

Despite being marked as SYSCALL_NEVER_FAILS, personality syscall still
might report a failure on some architectures due to obscure kernel
bugs.  Check for this unlikely case and let users know that their
kernel has gone bananas.

* personality.c (SYS_FUNC(personality)): Do not parse syscall return
value in case of syserror.

Do not truncate return value of get{,e}[ug]id and setfs[ug]id syscalls

This should not be a user visible change unless the kernel does
something completely unexpected.  In the latter case, let user see
what is going on.

* uid.c (SYS_FUNC(getuid), SYS_FUNC(setfsuid)): Do not truncate
tcp->u_rval to uid_t on exiting syscall, return RVAL_DECODED.

Enhance personality syscall decoding

* xlat/personality_options.in: Split into ...
* xlat/personality_types.in: ... personality types and ...
* xlat/personality_flags.in: ... personality flags.
* personality.c: Include "xlat/personality_types.h"
and "xlat/personality_flags.h" instead of "xlat/personality_options.h".
(SYS_FUNC(personality)): Print PER_MASK part of personality as
a symbolic value, and the rest of personality as a set of flags.
* tests/personality.c (main): Add more test cases.
* tests/personality.test: Update.

sh, sh64: fix syscall flags in several syscall entries

* linux/sh/syscallent.h (geteuid32, getegid32, setfsuid32, setfsgid32):
Set SYSCALL_NEVER_FAILS flag.
(fchown32): Set TRACE_DESC flag.
* linux/sh64/syscallent.h: Likewise.

Print personality value 0xffffffff properly

Value 0xffffffff of personality syscall first argument has a special
meaning, it is not a set of personality flags.

* personality.c (SYS_FUNC(personality)): If personality equals
to 0xffffffff, print it verbatim.
* tests/personality.c (main): Test it.

tests: add personality.test

* tests/personality.c: New file.
* tests/personality.test: New test.
* tests/Makefile.am (check_PROGRAMS): Add personality.
(TESTS): Add personality.test.
* tests/.gitignore: Add personality.

Enhance personality syscall decoding

* personality.c (SYS_FUNC(personality)): On entering syscall,
print first argument not as a hex value but as a set of flags.
On exiting syscall, print return code as a set of flags.
* NEWS: Mention this enhancement.

Set SYSCALL_NEVER_FAILS flag for personality syscall

Starting with commit
v2.6.29-6609-g11d06b2a1e5658f448a308aa3beb97bacd64a940, personality
syscall never fails to set the personality, but before commit
v2.6.35-rc1-372-g485d527 it still could return an error.
Starting with that commit, personality syscall never returns an error.

* linux/*/syscallent.h: Set SYSCALL_NEVER_FAILS flag in personality
syscall entries.

Add personality emulation flags

* xlat/personality_options.in: Add UNAME26, ADDR_NO_RANDOMIZE,
FDPIC_FUNCPTRS, MMAP_PAGE_ZERO, ADDR_COMPAT_LAYOUT, READ_IMPLIES_EXEC,
ADDR_LIMIT_32BIT, SHORT_INODE, WHOLE_SECONDS, STICKY_TIMEOUTS,
and ADDR_LIMIT_3GB.
