which is default data model with APP_ABI := arm64-v8a on android-ndk-r10b

ashwani over 10 years ago

Hi,

If I build a native code on android-ndk-r10b with APP_ABI := arm64-v8a. Which 64-bit data (LP64, LLP64, ILP4) model is used to compile the code?

Regards,

Parents

Thanks Matthew.
How and where could I confirm that "default for Android L, NDK10 and newer, is LP64"?

Linux is LP64 as is gcc by default for 64-bit architectures so it made sense to make the Android libraries and NDK LP64 as well. I don't think LLP64 or ILP64 were ever a consideration. You can always check the AOSP L preview gcc defaults or use readelf or gdb to verify a Bionic (or other) lib.
