0x100002ec0: b 0x100002d1c ; jump back to the dispatch loop I'd expect tail call based control flow - i.e. computing the jump destination at the end of each opcode function - to be nicer to the branch predictor because it could track targets separately. Currently that's hard to achieve in Rust. There's an experiment in progress to see if guaranteed tail calls can be added to the language https://github.com/rust-lang/rust/issues/112788 https://github.com/rust-lang/rust/issues/112788
