ARM has just announced ARMv8 architecture which not only support 32bit, but also adds support for 64bit execution. In ARM speak, this is AArch32 and AArch64. This is indeed exciting news for me as I’ve been waiting for this for quite some time now. Now, ARM, please make documentation for A64 ISA freely available soon!
Anton Korobeynikov published his Status of ARM platform support in LLVM and more slides. It’s interesting reading, you can find it here.
