Enablement of Genode's ARMv8 support

ARMv8 introduces a new 64 bit instruction set architecture (ISA). This implies that there exists a different general purpose register set as well as new instructions and opcodes that are not compatible with ARMv7 or ARMv6. While for high level languages like C or C++ the burden of opcode generation is transparently handled by the compiler, there are always cases (e.g, assembly, application binary interface, ELF format) that have to be handled specifically for each ISA. In this article I will describe the most important adaptions required to execute Genode on the ARMv8 architecture. Continue...
