2aace21a19 Remove the bogus exit status from _exit_with_stack_teardown. 
It should always be 0, and there's no reason to pass a constant in as
an argument.

stack for a0-a3. syscall is handling up to 6 arguments so
additional space is needed on the stack to avoid corrupting the
callers frame.

__popcountsi2 anymore as Clang generates inline instructions. However
prebuilt binary blobs still depend on libc.so to resolve __popcountsi2.

This patch changes the domain that the memory barrier operates on. Assumes
that the scope of bionic_atomic_barrier() does not include device memory,
memory shared with the GPU or any other memory external to the processor
cluster.

bf3ec9ad52 AArch64: Use LDXR/STXR instead of LDAXR/STLXR for bionic_atomic_cmpxchg() 
The bionic_atomic_cmpxchg() API states that the cmpxchg() will be done without
explicit memory barriers. LDAXR/STLXR semantics involve half barriers for
load/store.

This patch optimises cmpxchg() by using LDXR/STXR and avoiding unnecessary half
bariers. It also fixes the clobber list for all the bionic_atomic_*() functions.

e7c59f9e20 Fix compilation of crtbegin.c and pthread_debug.cpp. 
Because there was no default := for the aarch64 libc_crt_target_cflags,
the += was causing libc_crt_target_cflags to be recursively-defined
variable, which meant that when we were compiling crtbegin.c LOCAL_PATH
would be bionic/tests/ and we'd have -Ibionic/tests/include/ and find
none of our include files.

Also fix linking of pthread_debug.cpp, at least in the disabled mode.
The enabled mode was already broken for all architectures, and continues
to be broken after this change. It's been broken for long enough that
we might want to just remove it...

(aarch64 is using the FSF linker where arm uses the gold linker.)

This is a better solution than the old __warn_references because it's
a compile-time rather than link-time warning, it doesn't rely on something
that doesn't appear to be supported by gold (which is why you only used
to see these warnings on mips builds), and the errors refer to the exact
call site(s) rather than just telling you which object file contains a
reference to the bad function.

This is primarily so we can build bionic for aarch64; building libc.so
caused these warnings to fire (because link time is the wrong time) and
warnings are errors.

e210488e0d AArch64: Add initial support for AArch64 
This is the first patch out of a series of patches that add support for
AArch64, the new 64bit execution state of the ARMv8 Architecture. The
patches add support for LP64 programming model.

The patch adds:
* "arch-aarch64" to the architecture directories.
* "arch-aarch64/include" - headers used by libc
* "arch-aarch64/bionic":
    - crtbegin, crtend support;
    - aarch64 specific syscall stubs;
    - setjmp, clone, vfork assembly files.

It looks like we can probably just use the generic GCC stuff instead;
the generated code looks pretty similar. We should come back to that.

These routines are only used by the pthread implementation, and
__bionic_atomic_inc isn't used, so we can remove it.

dff7203ee9 Remove harmful attempts to be helpful in pthread_mutex functions. 
Most callers won't check for EINVAL, so it's best to fail early.
GCC takes the nonnull attribute as a guarantee that an argument
won't be NULL, so these hacks were already ineffective, which is
how we found that at least one commercial game was using NULL
as if it's a mutex, but actually getting no-op behavior.

ed45970ac5 Add cfi directives to all arm assembly. 
Since the ENTRY/END macros now have .cfi_startproc/.cfi_endproc, most of the
custom arm assembly has no unwind information. Adding the proper cfi directives
for these and removing the arm directives.

Update the gensyscalls.py script to add these cfi directives for the generated
assembly. Also fix the references to non-uapi headers to the proper uapi
header.

In addition, remove the kill.S, tkill.S, tgkill.S for arm since they are not
needed at all. The unwinder (libunwind) is able to properly unwind using the
normal abort.

After this change, I can unwind through the system calls again.

takes a pointer to a struct user_desc instead of a pointer to the
TLS itself. Rather than have to deal with this here, let's just use
the old __set_tls mechanism we used to use (and still use for the
main thread on all architectures, so it's not going away any time
soon).

ab61eb366a Switch to upstream sleep(3) and usleep(3). 
Also fix the signature of usleep, and the definition of useconds_t which
should be unsigned, as the 'u' in its name implies.

This patch also cleans up the existing FreeBSD hacks by moving the libm
stuff from <sys/cdefs.h> to a libm-private header, and adding comments
about the hacks we use to build FreeBSD source.

36d6188f8c Clean up forking and cloning. 
The kernel now maintains the pthread_internal_t::tid field for us,
and __clone was only used in one place so let's inline it so we don't
have to leave such a dangerous function lying around. Also rename
files to match their content and remove some useless #includes.

877ec6d904 Fix pthread_join. 
Let the kernel keep pthread_internal_t::tid updated, including
across forks and for the main thread. This then lets us fix
pthread_join to only return after the thread has really exited.

Also fix the thread attributes of the main thread so we don't
unmap the main thread's stack (which is really owned by the
dynamic linker and contains things like environment variables),
which fixes crashes when joining with an exited main thread
and also fixes problems reported publicly with accessing environment
variables after the main thread exits (for which I've added a new
unit test).

In passing I also fixed a bug where if the clone(2) inside
pthread_create(3) fails, we'd unmap the child's stack and TLS (which
contains the mutex) and then try to unlock the mutex. Boom! It wasn't
until after I'd uploaded the fix for this that I came across a new
public bug reporting this exact failure.

652289942d bionic: call stdio cleanup on exit 
As of 61e699a133, stdio clean up
functions are no longer registered in atexit and must be called
manually via __cleanup.

The issue this fixes is some static binaries linked against bionic
cannot output properly when piped or redirected because the buffer
is not flushed before closing.

This is done by pulling in exit.c (and other dependencies) from
netbsd.

The simplest workaround is to handle the indirection in userland and then
call the required system call directly.

2ecc164ae9 Remove the dependency on the non-uapi __kernel_nlink_t. 
The kernel doesn't have an nlink_t; it just uses the equivalent of
uint32_t. We already had a usable __nlink_t in the C library, so
let's just define our nlink_t in terms of __nlink_t, which is what
__nlink_t was meant for anyway.

Note that our struct stat just follows the kernel, and doesn't refer
to nlink_t anyway.

062092543f Clean up the 32-bit kernel support, fix LP64 fcntl declaration. 
In practice, thanks to all the registers the stubs don't actually change,
but it's confusing to have an incorrect declaration.

I suspect that fcntl remains broken for aarch64; it happens to work for
x86_64 because the first vararg argument gets placed in the right register
anyway, but I have no reason to believe that's true for aarch64.

This patch adds a unit test, though, so we'll be able to tell when we get
as far as running the unit tests.

40596aa005 Make cpp.py less braindead. 
The old code ignored operator precedence (!), despite having two tables
of operator precedence. The code's still pretty awful, but I've cleaned
it up enough to fix this, the most important bug.

This patch lets us correctly clean the uapi unistd.h, stat.h, and swab.h files,
and also fixes the mess we were already making of various old kernel
header files. I've added a bunch more tests, fixed the existing tests that
the existing script was already failing (!), and changed the script so that
the tests are run every time the script is run.

We can probably remove some of the old kernel header files that we were
parsing incorrectly, but we can worry about that later.

c3f114037d <pthread.h> fixes and pthread cleanup. 
<pthread.h> was missing nonnull attributes, noreturn on pthread_exit,
and had incorrect cv qualifiers for several standard functions.

I've also marked the non-standard stuff (where I count glibc rather
than POSIX as "standard") so we can revisit this cruft for LP64 and
try to ensure we're compatible with glibc.

I've also broken out the pthread_cond* functions into a new file.

I've made the remaining pthread files (plus ptrace) part of the bionic code
and fixed all the warnings.

I've added a few more smoke tests for chunks of untested pthread functionality.

We no longer need the libc_static_common_src_files hack for any of the
pthread implementation because we long since stripped out the rest of
the armv5 support, and this hack was just to ensure that __get_tls in libc.a
went via the kernel if necessary.

This patch also finishes the job of breaking up the pthread.c monolith, and
adds a handful of new tests.

hand-written __exit_with_stack_teardown stubs used to try to cause
SIGSEGV if the exit system call returned (which it never does, so
that dead code disappeared).

Also move the sigprocmask into the only case where it's necessary ---
the one where we unmap the stack that would be used by a signal
handler.

feaa89a1bc AArch64: Add support for AArch64 to the syscall interface 
This patch adds support for AArch64 to the syscall interface. The kernel
implementation exports a set of canonical syscalls, therefore some of
the userspace exported syscalls are implemented as stubs based on the
canonical set.

From the release notes:

  Changes affecting current and future time stamps:

    Libya has switched its time zone back to UTC+2 without DST,
    instead of UTC+1 with DST.  (Thanks to Even Scharning.)

    Western Sahara (Africa/El_Aaiun) uses Morocco's DST rules.
    (Thanks to Gwillim Law.)

  Changes affecting future time stamps:

    Acre and (we guess) western Amazonas will switch from UTC-4 to UTC-5
    on 2013-11-10.  This affects America/Rio_Branco and America/Eirunepe.
    (Thanks to Steffen Thorsen.)

    Add entries for DST transitions in Morocco in the year 2038.
    This avoids some year-2038 glitches introduced in 2013g.
    (Thanks to Yoshito Umaoka for reporting the problem.)

6b53c2349a Fix the exit syscall stub's name. 
I've left the exit_group syscall as _exit because otherwise we'd have to
convince the compiler that our _exit (which just calls __exit_group) is
actually "noreturn", and it seems like that would be less clean than just
cutting out the middleman.

We'll just have to trust ourselves not to add anything to SYSCALLS.TXT
that ought to be private but that only has a single leading underscore.
Hopefully we can manage that.

instead.

This cruft dates from a time when bionic would only output syscall
contants for the syscalls mentioned in SYSCALLS.TXT. I fixed that
a long time ago, but never followed through with the removal of what
was then confusingly called "stub" and was recently renamed "custom".

We couldn't fix this for 32-bit because there's too much broken
code out there. (Pretty much everyone asks for real-time
scheduling for all their threads, and the kernel says "don't be
stupid".)

ac6bc31942 Remove new aligned memcpy path for cortex-a15. 
For some reason the new cortex-a15 memcpy code from ARM is really bad
for really large copies. This change forces us to go down the old path
for all copies.

All of my benchmarks show the new version is faster for large copies, but
something is going on that I don't understand.

I originally modified the krait mainloop prefetch from cacheline * 8 to * 2.
This causes a perf degradation for copies bigger than will fit in the cache.
Fixing this back to the original * 8. I tried other multiples, but * 8 is th
sweet spot on krait.

Let's have both use rt_sigprocmask, like in glibc. The 64-bit ABIs
can share the same code as the 32-bit ABIs.

Also, let's test the return side of these calls, not just the
setting.

6e38072add Wrap sprintf()/snprintf() macros to prevent expansion errors. 
Previously, FORTIFY_SOURCE used single macros to define these standard
functions for use with clang. This can cause conflicts with other macros used
to call these functions, particularly when those macros expand the number of
arguments to the function. This change wraps our macro definitions, so that
expansion properly takes place for programmer arguments first.
