Start64!Back in September of last year after Apple unveiled the iPhone 5S smart-phone with a 64-bit processor, they said they would ultimately open-source their 64-bit ARM compiler back-end... A half-year later, we're finally seeing this code that yields another AArch64 back-end for LLVM.

It took Apple quite a while to open-source their 64-bit ARM LLVM back-end and in the months since -- and going back further in 2013 -- the LLVM development community has taken on to developing their own AArch64 back-end with support of several ARM SoC vendors. Now that Apple has finally published their back-end, which they consider to be production quality and is used right now for compiling iOS and related components for the 64-bit ARM Apple hardware, they are wanting to merge their back-end into LLVM.
