Linux on ARMBack in March Apple open-sourced their ARM 64-bit LLVM back-end (dubbed ARM64) many months after other ARM vendors had already developed a competing 64-bit ARM back-end (dubbed "AArch64" as ARM's official name for architecture).

Since Apple opened up their back-end, Apple and outside LLVM developers have been working to converge the competing 64-bit ARM back-ends into a single 64-bit ARM target. That work is now complete.

The LLVM 64-bit back-end merging that they have been doing over the past several weeks is merging all of the features/improvements found within the existing AArch64 compiler back-end into Apple's "ARM64" back-end that was overall in better shape and easier to be on the receiving end of this work...
