Rosetta runs AVX2, FMA, BMI1/2, F16C and MOVBE, but, unlike an Intel host, it has neither RDSEED, CLWB nor RDPID. --to-rosetta converts everything --to-intel does and lowers these three as well: - RDSEED becomes RDRAND (the /6 form of the same opcode), which also returns a random value and sets CF. - CLWB only writes a cache line back, so it becomes a NOP of the same length. - RDPID becomes a load of 0 through an optional stub: Rosetta's TSC_AUX is a constant, not a processor index, so every thread reports processor 0. A site with no movable instruction after it for the jump is kept. The flag implies --to-intel and conflicts with --windows. It is independent of --macos: it only changes what the conversion produces, so --macos alone leaves these instructions as they are, as on an Intel Mac, and a title for Rosetta is relinked with --macos --to-rosetta. Intel output is unchanged: the target is a parameter of the converter, Intel by default.
