to link a trivial program but fails w/o the presence of libc.so and libdl.so

"atexit" isn't defined in libc.a for x86/mips (unlike their arm's counterpart).
Include atexit.S otherwise app using atexit() may fail to link statically.
Also, add crtbegin.c to brand crtbegin_static/dynamic.c with .note.ABI-tag
section of given API level. See $NDK/gen-platforms.sh

This patch removes all prebuilt C runtime object files from
the ndk/platforms/ directory. We replace them with equivalent
assembly sources lifted from the following directories:
bionic/libc/private/ (for __dso_handle.S and __dso_handle_so.S)
bionic/libc/arch-$ARCH/ (for all others)
Note: This requires that your NDK's gen-platforms.sh script be
capable of rebuilding the object files from sources.
See https://android-review.googlesource.com/36822
The goal here is to make it much easier to update these files,
and track their changes relative to the content of bionic/lib.
For example to fix the following issues in the future:

Apply changes in bionic/libc/arch-x86/include/machine to
development/ndk/platforms/android-9/arch-x86/include/machine:
commit 5fbf2e09921723cfdea75e83c1fac2080f0ad564
Change-Id: Ie0fe711ae4c866d9c1300430d5e9613ccb82da22
The atomic operations exported by the platform's C library do not
provide full memory barriers. This can result in incorrect results
when NDK machine code linked against them runs on multi-core devices.
While the bug has been fixed in the platform, this NDK header change
ensures that any source code that includes <sys/atomics.h> will end
up using a correct implementation of these functions, based on the
corresponding GCC builtins.
These builtins always provide a full barrier and have reasonable
performance. Application developers who depend on <sys/atomics.h>
should recompile their unmodified sources against this version
of the NDK as soon as possible.
Corrected for example <asm/io.h> to include io_32.h instead of io_64.h
(which is missing, BTW).

We don't use these since NDK r5, since we now provide
customized versions of the library under

The previous header and implementation were incorrect and didn't produce
correct results. This has been fixed in the internal Gingerbread branch.
Technically, this could result in ABI breakage, but the chances are very
low, and there are no official x86 Gingerbread release yet.

Remove the prebuilt system shared libraries and unified symbol files
from development/ndk. We don't need them anymore:
- the unified symbol files are replaced by separate functions/variables
symbol list, which were added in a previous commit, i.e.:
libc.so.txt --> libc.so.functions.txt
libc.so.variables.txt
- the shared libraries are now generated on the fly by the NDK
gen-platforms.sh script, from the functions/variables symbol lists.
Note that we need to keep the static libraries and runtime objects,
they are required to build the cross-toolchains and target binaries.
Change-Id: Ifa0a7f2d741ed32b80216561ca3f17e67df06ce9
This change introduces separate symbol lists for functions
and variables of each NDK system shared library.
Note that we don't remove the unified symbol files yet. This
will be done later when we complete other changes under ndk/,
namely the ability to generate platforms trees containing shell
libraries generated directly from them.
These files were generated using the following:
cd development/ndk
for DIR in platforms/*/*/lib; do
for ARCH in arm x86; do
$NDK/build/tools/gen-system-symbols $DIR $DIR/../symbols
done
done
This means that the symbol lists were generated by parsing the
existing prebuilt shared libraries under platforms/ and extracting
their function and variable names.

This updates the platform files for API level 9 on x86 to
the binaries built from the internal Gingerbread branch
containing the back-ported AOSP x86 support patches.
Change-Id: I5bc43b4a5c346f7fab8eb57289803edc0c0f2d75
This change sanitizes the x86-specific platform headers and libraries.
It does two things:
- Remove the stuff under android-3/arch-x86
- Update the content of android-9/arch-x86 from a recent AOSP
full_x86-eng build (see caveats below).
Some files appear to move because they didn't change (e.g. kernel headers).
This change was generated by following these steps:
1/ Build full_x86-eng from the AOSP tree
2/ From $ANDROID_ROOT/ndk, run:
build/tools/dev-system-import.sh --direct --arch=x86 9
3/ Under $ANDROID_ROOT/development/ndk, do:
git rm -r android-3/arch-x86
git add android-9/arch-x86
git checkout -- android-9/include
git ls-files -o | xargs rm
git commit
IMPORTANT:
The AOSP tip-of-tree used to generate these files
includes post-Gingerbread changes !!
The final version of the android-9/arch-x86 files will have to
be generated from the gingerbread branch after we back-port all
x86-support changes to it.
These binaries are thus not final, but can be used to generate
working experimental NDK packages, including prebuilt GNU libstdc++
and STLport binaries that implement -fstack-protector correctly.

This patch updates the system C and C++ libraries used for
the x86 ABI. We remove the old binary targetting API level 5
(Eclair) since we don't support x86 on it anyway, and put new ones
generated from the AOSP tree with the full_x86-eng build product.
This is necessary to be able to prebuild STLport binaries for
the x86 NDK.
The binaries corresponding to the AOSP platform/bionic.git tree
using the following SHA-1, when building full_x86-eng:

Remove all duplicate platform files, i.e development/ndk/platforms/android-N now
only contains files that are introduced in API level 'N' and not found in level 'N-1'
(This makes it easier to manage independent platform release branches, and makes
platform additions trivial to examine and maintain).
Move samples that depends on features of API level 'N' into platforms/android-N/samples
+ update tests/run-all.sh accordingly

We now rely instead on the content of $NDK/sources/cxx-stl/system/include
that is automatically used if a module has C++ sources.
Change-Id: I4319d9260fcf9fb31c59c2f21ca64b536725d4f5
The idea is to allow developing the NDK in the open, while
having the platforms and samples under a private branch until
the corresponding release are open-sourced.
