let’s change topics a bit and use a swear word…Java “Java” That’s right, I said it, at a C++ conference…Java At least I didn’t say “Rust”…Compiling Java just in time Avoiding unnecessary overhead is constructing an intermediate representation (IR) of a method is a standard process. When compiling from Java bytecode, however, we can eliminate that overhead. The bytecodes themselves are an IR. Because they ideal IR for compilation, but they can easily be used for that purpose. — 1997 (read)Compiling Java just in time Avoiding unnecessary overhead is crucial for fast compilation. In many compilers, constructing
