At which point does this pay off the emulation overhead? Fex has a lot of work to do to bridge two ISAs while going through the black box of compiler output of assembly, right?
afaia emulators like Fex are within 30 to 70% of native performance. On the fringes worse or better. But overall emulation seems totally fine. Plus emulator technology in general could be used for binary optimization rather than strict mappings, opening up space for more optimization.
