Hi,

I received the following answer to the question (which came up a few weeks ago on this mailing list) about UMULL on ARM/Android platform:

The simple answer is yes, UMULL will be available. There is some detail though:

The NDK supports ARMv5TE or ARMv7 - in the form of armeabi and armeabi-v7a, both of these are
capable of UMULL instructions.

For armeabi binaries you will need to be in ARM state (the instruction is not supported by Thumb), for armeabi-v7 either
ARM or Thumb2 provide the instruction.

This is from a thread I started on the android-ndk mailing list: https://groups.google.com/d/topic/android-ndk/ShF1Rv9DLLg/discussion

Best,
Charles
