By AOT I mean "Ahead of Time" compilation, not JIT. I.e. the process of not using runtime profiling information to compile optimized code, but compiling it with static information.

Assuming https://webkit.org/blog/7691/webassembly/ is still up to date(?), then I suppose I am referring to compiling with OMG tier up front instead of the BBQ tier.

The article writes "Since WebAssembly does not require any type speculations, we only use tiering to conserve compile time.", suggesting that the compilation with OMG could be done without needing to collect any profiling data. (in other words, compile with OMG "ahead of time")
