3e1498c4c4
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.
