I'm reviewing this now. :p Some general general questions: 1. v3 drops intrinsics in favour of inline asm -- is that for performance reasons? 2. In the mono->stereo float case, the Cortex A9 code is actually slower. I recall that in a previous thread, we had this sort of situation on one of Panda/Beagleboard. Do we need some way to pick and choose implementations? 3. How shall we go about enabling this code? Have a configure time check for some instructions that are needed, build it in if available, and then run-time detection should pick the right code path? I'll take a closer look at things, run some tests, and start pushing this work. I'll also be moving all the test code to src/tests/cpu-test.c where the x86 tests have been consolidated, so running tests on different boards should become a lot less painful. Thank you very much for your patience! Cheers, Arun
