pub fn optimizations_fired_vm(source: &str) -> Vec<&'static str>Expand description
The optimizations that fired while compiling source to VM bytecode — the
third path, after AOT codegen and the run-path optimizer. Surfaces the
VM-compile-time opts (constant-divisor magic division, VM i32 narrowing)
the other two traces cannot see. Compiles only (no execution), so it is fast
and needs no program arguments.
