Unfortunately, legacy .so files for ARM don't have a correct crtbegin file.
Consequently, we have to grandfather the old __dso_handle behaviour.
Add some ifdefs for ARM to allow it to use the old code until we can work
out a transition.

libcutils/mspace.c includes libc/bionic/dlmalloc.c, we need to
take care of the fact that any internal C library function cannot
be used from it.
Change-Id: I0bc81ae090b7ac2d464f26b97fc6b94a08cdad9c
Our dlmalloc implementation currently calls abort() when it detects
that the heap is corrupted, or that an invalid pointer is passed to
one of its functions.
The only way to detect this is because abort() will force-fully
crash the current program with a magic fault address of '0xdeadbaad'.
However, this is not really well documented, and a frequent topic
on the android-ndk forum (among others).
This change makes our dlmalloc code dump a simple message to the
log just before the abort() call (and hence before the stack trace)
to better help identify the problem.

NOTE: This is a back-port from the internal HC branch.
This patch fixes a leak that occurs when creating a new
thread-specific DNS resolver state object.
Essentially, each thread that calls gethostbyname() or getaddrinfo()
at least once will leak a small memory block. Another leak happens
anytime these functions are called after a change of the network
settings.
The leak is insignificant and hard to notice on typical programs.
However, netd tends to create one new thread for each DNS request
it processes, and quickly grows in size after a > 20 hours.
The same problem is seen in other system processes that tend to
create one thread per request too.
The leak occured becasue res_ninit() was called twice when creating
a new thread-specific DNS resolver state in _res_get_thread().
This function could not properly reset an existing thread and was
leaking a memory block.
The patch does two things:
- First, it fixes res_ninit() to prevent any leakage when resetting
the state of a given res_state instance.
- Second, it modifies the _res_get_thread() implementation to
make it more explicit, and avoid calling res_ninit() twice
in a row on first-time creation.

It adds two functions sigsetjmp and siglongjmp
that fix compiling errors in bluetooth and mksh.
Copy directly from sigsetjmp.S of OpenBSD.

The source file is not part of the C library build, so the Android.mk
is unaffected. In other words, this source file was never compiled.

After this change, SIGRTMAX will be set to 64 (instead of 32 currently).
Note that this doesn't change the fact that our sigset_t is still defined
as a 32-bit unsigned integer, so most functions that deal with this type
won't support real-time signals though.

Plus a hack in cpu-features.h to avoid errors like this:
bionic/libc/arch-arm/bionic/strcpy.S: Assembler messages:
bionic/libc/arch-arm/bionic/strcpy.S:42: Error: bad instruction `pld(r1, #0)'
(The alternative would probably have been to pull in the build change
that defines __ASSEMBLY__, but I don't want to do any more than necessary.)

Add missing declarations:
INET_ADDRSTRLEN
IN6_IS_ADDR_MC_NODELOCAL
IN6_IS_ADDR_MC_GLOBAL
It has been reported that these prevent compilation of the Boost libraries
with the NDK. The corresponding patch has already been performed under
development/ndk/platforms/android-3/include.

This patch improves the handling of 64-bit parameters in syscalls on ARM.
The ARM EABI mandates that 64-bit quantities be passed in even/odd register
pairs, which requires special treatment.
This allows us to simplify our implementations of pread() and pwrite()
and remove the C stubs for pread64() and pwrite64().
Also add ftruncate64() to <unistd.h>

Bug 3107933
The second declaration came from an incorrect change in AOSP.
The eventfd stubs are not affected by this, they are already correct.

asm() conflicts with userland code compiled with -std=c99, the userland
libc should only use __asm__() instead. Therefore, this transformation
has to be applied to all exported headers.
This only changes arch-arm/asm/byteorder.h.
Change-Id: I1cf88c37201c3a91668d387293a18885c316d53c
If compiling userland code with -std=c99, the current header produces an
error. The content of this header originally is a kernel internal header,
where asm() is acceptable. In a header visible to userland, this should be
__asm__ instead.

This adds the cpu_set_t type definition and related functions

Add a new header that defines __ANDROID_API__ as a constant integer

by <sys/cdefs.h>

NOTE: This header is already provided by the NDK's platform headers.
for levels 3 to 9.
The mkdtemp() function is implemented in libc/stdio/mktemp.c but not
exposed in stdlib.h. This change adds the prototype to stdlib.h.
Change-Id: I5a98650c665d2e45b2cf6ed3382742f7bdc7c88a
The above prototypes are missing from libc/include/wchar.h but
the functions are present (although with a limited implementation)
in libc.

64-bit pread() and pwrite() is needed for ZipFileRO to be able to read

it.
Also fix a license header that was apparently mangled.

Will also need to do gethostinfo, but that's probably about it.
It was cleaner to do it at this level, rather than speaking in terms

Originally, there are _rand48 (in libc/bionic/_rand48.c) and __rand48
(in libc/stdlib/_rand48.c) implemented in bionic. Besides the naming,
the functionality is identical. This patch removes the duplicated
_rand48. Also, drand48 and erand48 are modified accordingly.

This change allows an executable to call its destructor functions
(declared with __attribute__((destructor))) to be properly called
when it normally exits.
Note that this is different from calling the destructors of a shared
library when it is unloaded with dlclose() or through program exit,
which are already supported.

with a clear "MISSING" in comments in order to locate
them later.

libc: optimize memmove() with memcpy() if possible.
The get_malloc_leak_info() currently asssumes that the totalMemory out parameter
was pre-initialized to zero before the routine is called. If it is not then the
accumulated totalMemory value will be incorrect. It is likely that many callers
will simply allocate totalMemory on the stack with no initialization and assume
that get_malloc_leak_info will set the proper value.
As an example, the caller in frameworks/base/core/jni/android_os_Debug.cpp
calls get_malloc_leak_info() with the address uninitiazed stack variable
for totalMemory. It is probably best to fix this in get_malloc_leak_info.

1. Make the feature test work by excluding known-deficient processors, so
we don't have to maintain a complete list of all the processors that support
REV and REV16.
2. Don't abuse 'register' to get an effect similar to GCC's +l constraint,
but which was unnecessarily restrictive.
3. Fix __swap64md so _x isn't clobbered, breaking 64-bit swaps.
4. Make <byteswap.h> (which declars bswap_16 and friends) use <endian.h>
rather than <sys/endian.h>, so we get the machine-dependent implementations.
