Surprise! I'm reviewing this now. :p
Some general general questions:
1. v3 drops intrinsics in favour of inline asm -- is that for
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
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!
