This patch moves the definitions of all defaults to dev-defaults.
This should make it easier in the future to upgrade the toolchains
or target binaries.

These options are obsolete. Instead, the build-gnu-libstdc++.sh
script can be used to rebuild the GNU libstdc++ library directly.

Change-Id: I281653915a5bce272ac8d593038291b73270c128

+ Add a patch to disable libtool versioning when building
  the GNU libstdc++.so

Auto-generate the <android/api-level.h> header which contains
a single macro definition for the native API level that the code
is built against.

Previously, the corresponding files were stored under
../development/ndk and required manual updating, which is tedious
and error-prone

+ remove obsolete dev-generate-api-levels.sh script

Change-Id: Ibe482281dff7d86e0a46f6dd9d7096e3cc790e8e

This flag is used to indicate that you only want to generate
sysroots that can be used to build the host toolchains, so this
will only copy the system headers and static objects/libraries.

All samples and shared libraries are ignored, and symlinks are not
used to speed up execution (so --no-samples and --no-symlinks are
implied)

+ Drop --no-samples, and use --samples instead, since we only
  want to regenerate the samples directories when generating
  package releases.

+ Rename --no-symlinks to --fast-copy

Ensures that the list of platforms is sorted in proper numerical
order, i.e. that android-10 appears after android-9 and not before
android-3

+ Don't make error message is a symbols directory doesn't exist
(e.g. on x86 for API level < 9)

Change-Id: I1fa5b8a43df1de4ee51059065d5c3e24dc90a5e2

Introduces a new script that can do the opposite of
dev-platform-expand-all.sh, which is to compress the content of
/tmp/ndk-$USER/platforms into /tmp/ndk-$USER/platforms-compressed

This ensures that if two successive platforms to define the same
header or symbol list, only the first is copied to the destination.

You would typically use this script, then compare the content of
/tmp/ndk-$USER/platforms-compressed with the one of
$TOP/development/ndk/platforms to check what has changed.

Change-Id: Id277f786789a2b2395259e0f392d3e9975526197

This patch provides a new script that can call dev-platform-expand.sh
for all API levels and all architectures automatically. This is useful
to build a fully expanded tree in /tmp/ndk-$USER/platforms from the
content of development/ndk

Note that this only copies files, i.e. headers and symbol lists,
it doesn't generate any shell libraries.

Ensures that the platforms are sorted in numerical order, i.e.
that android-10 will appear after android-9, instead of before android-3

+ Deal with non-existing symbols directories

This patch adds a new script named 'gen-platforms.sh', used
like 'build-platforms.sh' to generate final platform sysroot
directories. They take the same parameters.

The difference between these two scripts is that gen-platforms.sh
does generate shared libraries from functions/variables list files
found in development/ndk/platforms/android-$PLATFORM/arch-$ARCH/symbols/

built-platforms.sh instead copies the files from .../lib directory
instead.

In a future patch, we're going to remove all prebuilt shared libraries
from development/ndk, and replace them with symbol files. We will also
remove build-platforms.sh and replace its usage by gen-platforms.sh

Change-Id: I2720095f0fcbbbfb5e1374cd1fdaac898ec53393

This patch introduces the dev-platform-imports.sh script.
Its role is import system headers and libraries from a fresh
Android platform build and use them to populate a special
"import directory" (e.g. /tmp/ndk-$USER/platforms-import/)

The import directory will contain only headers and symbols
file. For each system shared library, two symbol files will
be generated:

  - $DST/android-$PLATFORM/arch-$ARCH/symbols/$LIBNAME.functions.txt
  - $DST/android-$PLATFORM/arch-$ARCH/symbols/$LIBNAME.variables.txt

The idea is that we're going to remove all prebuilt shared libraries
from development/ndk in a future patch. Instead, we will store the
symbols and generate shell libraries when calling build-platforms.sh

We need to keep the prebuilt static libraries though because they
are required to build the toolchain files (plus, some NDK developers
do use them to generate static executables).

+ add gen-system-symbols.sh which does the symbol file generation
  plus the filtering of undesirable symbols in our system libraries.

This patch adds sources/cxx-stl/gabi++/src/one_time_construction.cc
and removes the dependency on libstdc++ from GAbi++

The implementation is based on pthread which is always provided by
the C library on Android (the latter is always linked to generated
binaries, so there is no need to list it in LOCAL_EXPORT_LDLIBS).

+ Add unit test to check that one-time-construction works properly.

Change-Id: Ic4af9f19814cf9efd7caa60bc84e9c03fc4bf656

This patch fixes a bug in definitions.mk regarding the list
of installable dependencies for a given application. It ignored
prebuilt shared libraries.

+ Fix another bug where we were not using the prebuilt GAbi++
  libraries when using APP_STL := gabi++_shared/static

This patch adds build-host-sed.sh that can be used to rebuild
host versions of the sed tool, which will be placed under
prebuilt/<system>/bin/

This is mainly for native Win32 support, since we can't rely
on having a working sed in this environment.

A future patch will modify the NDK build system to use the
prebuilt binary automatically.

+ Add prebuilt/ to .gitignore
+ Remove prebuilt/ in dev-cleanup.sh

Change-Id: Ibe3561c189e90dde68023b7cbe1e9dc03dff1004

This patch modifies the helper functions inside prebuilt-common.sh
to distinguish between host and target builds more easily.

A target build is used to build target Android binaries, while a host
one is used to build binaries that will run on the host machine, i.e.
invoked by the NDK build script.

We will use host builds to generate the Windows helper binaries that
the NDK depends on (sed, awk, make, etc...) in future patches.

Change-Id: I19d6f065aa1e3c25b24e4031b4199501a242c141

This patch allows any script to source prebuilt-common.sh
properly. Before that, only patches in the same directory,
i.e. build/tools/, could source it without errors.

Note: To do that, the parent script must define NDK_BUILDTOOLS_PATH
to point to the build/tools/ directory. If the variable is not defined,
prebuilt-common.sh assumes that it is sources from build/tools/

Change-Id: If91360a0a10571f968049003c8f7192ad98c7f5c

This patch adds a new function to prebuilt-common.sh that can
return the install location of prebuilt host binaries. It
currently is: $NDK/prebuilt/$HOST_TAG/

This will be used to store host binaries, like the Win32 versions
of GNU Make, Awk, Sed and others.

Change-Id: I8a543b4f4d6b728e13046f3759a5b8584cea6001

This patch changes the definition of HOST_OS to 'cygwin' when
we detect that the build system is invoked from a Cygwin-compatible
GNU Make program.

The old value of 'windows' will now be used for the case where the
build system is invoked from a vanilla Win32 GNU Make binary, e.g.
from a standard Windows shell.

First step towards getting rid of Cygwin.

This patch modifies our build of stlport to include the GAbi++
runtime in order to support RTTI.

Change-Id: I8ff1853ad886e217f3d0d8a9366fc5075c63cc34

Also, for now we still need to depend on the system libstdc++
to implement one-time-construction properly. We should probably
implement that in GAbi++ itself, but this will come in another
patch.

Note that the system libstdc++ uses private Bionic functions
that cannot easily be used in the NDK. Especially those related
to device-specific memory barriers. A correct NDK implementation
will likely use pthread mutexes instead.

This patch ensures that run-tests.sh uses an exact match.
Before that, when using --test=test-stlport, it would
try to run both test-stlport-rtti and test-stlport

Change-Id: Id67e0e783b559639240d49f6c6803f5e71b1c065

This patch modifies download-toolchain-sources.sh so that it
creates a SOURCES file listing the SHA-1 states of every toolchain
git repository that has been downloaded.

Similarly, build-gcc.sh is modified to copy the file to the final
install location / archive.

Change-Id: Ifcc40a7e671c6e3f23613ac8bcc705bb9b9be448

This patch modifies the build system to allow one to
list several C++ source file extensions in LOCAL_CPP_EXTENSION.

+ Check the value of LOCAL_CPP_EXTENSION and warn about values
  that do not start with a dot (and ignore them).

Note that this doesn't change the default (which is to use '.cpp')

Change-Id: I0b5dfe8699f90955560cd0dbf9f52336970aaabd

This patch adds a new C++ runtime that can be used by modules
by setting APP_STL to either 'gabi++_static' or 'gabi++_shared'
in their Application.mk

GAbi++ is an alternative to the GNU libsupc++ that provides
RTTI support (with exceptions added in the future).

The goal is to use it to support RTTI (and later exceptions)
with our version of STLport, or even a different non-GNU STL.

+ new build-gabi++.sh script to rebuild the prebuilt libraries
  from sources.

+ support in rebuild-all-prebuilt.sh

+ support in package-release.sh

+ Unit test to check that RTTI actually works, both in the
  static and shared library case.

Change-Id: I7e73a31a4d24b5baa36fef357b69064c192ddc56

This patch introduces build/tools/builder-funcs.sh which contains
several functions that can be used to build source files into
static or shared libraries either directly or with the help of
an auto-generated Makefile (in order to allow for parallel builds).

Most of the functions come originally from build-stlport.sh which
has been modified to use the new stuff in builder-funcs.sh

Other NDK scripts will use this in the future to rebuild other
prebuilt binaries.

+ Support for NDK_CCACHE to speed up rebuilds. E.g. build-stlport.sh
  now takes 0.9s on my machine (used to be 26s before that).

Change-Id: I8ef97e62987f6aac6713821455d9a1ddcbbde796

This is a new variable that can be used to specify that a
given module relies on C++ exceptions or RTTI.

This is done for several reasons:

- First, we want to avoid always linking GNU libsupc++
  to every final binary, because we're soon going to
  provide an alternative.

- Second, it is useful to declare prebuilt binaries that
  have been compiled with these features. It allows the
  final link to work correctly.

Note that the change is backwards-compatible. You can still
use -frtti or -fexceptions in your compiler flags to enable
the features too.

Fix 1: Ensure shared libraries can be loaded: When running
test programs on the device that rely on a shared library,
ensure that LD_LIBRARY_PATH is properly define to allow the
program to load normally.

Previously, launching the program from the script would fail
with a "Can't link ..." error.

Fix 2: Build unit tests in a non-random directory:

This patch changes run-tests.sh to build all unit tests in a
non random directory (/tmp/ndk-$USER/tests/build/).

This speeds up (about 2x) running the test suite when NDK_CCACHE
is being used, because the content of the auto-generated dependency
files are no longer random anymore.

Change-Id: I0c24d5b50cca4a36a0b7a05cad1e0c2dbcbe4822

This patch modifies the way the NDK build script computes the
value of NDK_PROJECT_PATH when it is not already defined.

If we are in the project's top-level directory when ndk-build
is invoked, we can use the value '.' for NDK_PROJECT_PATH.

This reduces the length of all paths passed to build commands
(source files, object files, binaries), which can be useful
for modules with a ton of sources (especially on Cygwin where
the maximum command-line lenght is quite limited).

Change-Id: I35a60df243c156690dc3020983b6232cd9b92ec6

Ensure that if 'foo' imports static library 'bar' which
imports static library 'zoo', then libfoo.so will be linked
against both libbar.a and libzoo.a

Before this patch, only libbar.a was used, which resulted
in a link error.

Change-Id: Icabb2d8eaa4c09b12d00b71919b4c3723d4f90e6

This patch ensures that imported shared libraries are now copied
to the install location (libs/<abi>) by default. Previously, one
had to list them explicitely in APP_MODULES to do that (only
top-level project modules were installed).
