i really like the superset CFG idea, but the following are noteworthy for anybody planning to read the article: - ~4.75x runtime speed increase (significantly slower than box64, faster than QEMU), 7x executed instruction count increase, 50x binary size increase - emulates x86 abi until it calls out to external - has to emulate a large part of x86 cpu state like EFLAGS, compute complex movs individually, etc - only supports single-thread binaries - no exception handling/unwinding - doesnt support the full ISA |
