InterlockedExchangeAdd equivalent

Note: This was originally posted on 11th February 2013 at http://forums.arm.com

I'm porting a Windows application to an ARM® Cortex-A9 based system running Ubuntu 12.04 and I need something equivalent the Windows function InterlockedExchangeAdd(). Is there a function like this available for ARM? If not, can anyone provide some equivalent assembly code?

Hmm, depending what you are doing with them you are probably missing a barrier which ensures ordering relative to other instructions in the instruction stream. See http://infocenter.ar...ookbook_A08.pdf
