Even the F32 ones?

Anton,

As discussed, we might better put the FP helpers first, then deal with
the REM and Memset later. If Sandeep's patch passes all tests, you can
apply that and I'll merge to our changes later. If we have anything
extra, I can send together with the other patches later.

We sent a few patches already, but nothing too comprehensive, to be honest.

Unfortunately we don't have many people looking into LLVM, so the flow
of patches is lower than we'd like. We hope to get more active now,
helping the new MC for ARM/ASM and ARM/ELF, but I can't guarantee
we'll do as much as it's expected of us. ;)

About the A9 scheduler, I'll have a look (but I'm not the expert). ;)
