Precise control over memory layout and allocation which can translate into massive performance gains of several orders of magnitude. "Can translate" is not "translates to". Performance gains can be achieved when executing an efficient instruction set over a performant VM. Are you arguing that the JVM falls short as opposed to a browser in that regard? Also, with most operating systems, physical memory is abstracted from user-mode processes entirely. Kernel-mode is a different story, but I fail to see how a browser/WASM in user-mode do better than a JVM in user-mode in that regard. LLVM IR is unstable and low level. Interesting. What makes an instruction set "stable"? Is this about being backwards/forward compatible? About being encoded/decoded efficiently? What about the actual APIs exposed by the browser to WASM? Are those considered "stable"? Browsers today "break" all the time - inconsistencies between minors of the same browser, let alone different browser vendors.
