+### Initial support for x86_64 + +The x86_64 code support has been revived and enabled for qemu. While it started +as PoC and the only supported platform is an emulator, there's interest in +enabling additional platforms. It would allow to access more than 4GiB of memory +at runtime and possibly brings optimised code for faster execution times. +It still needs changes in assembly, fixed integer to pointer conversions in C, +wrappers for blobs, support for running Option ROMs, among other things. + ### Add significant changes here
