现在让我们看看通过 Cargo 构建和运行 “Hello, world!” 程序有什么不同！在 hello_cargo 目录 下，输入下面的命令来构建项目： $ cargo build Compiling hello_cargo v0.1.0 (file:///projects/hello_cargo) Finished dev [unoptimized + debuginfo] target(s) 的输出。Cargo 发现文件并没有被 改变，所以它并没有重新编译，而是直接运行了可执行文件。如果修改了源文件的话，Cargo 会在运行之前重新构建项目，并会出现像这样的输出： $ cargo run Compiling hello_cargo v0.1.0 (file:///projects/hello_cargo) Finished dev [unoptimized + debuginfo] target(s) } 现在使用 cargo run 命令，一步完成 “Hello, world!” 程序的编译和运行： 23/600 Rust 程序设计语言 简体中文版 $ cargo run Compiling guessing_game v0.1.0 (file:///projects/guessing_game) Finished dev [unoptimized + debuginfo]

ex- pression is over, and the next one is ready to begin. Most lines of Rust code end with a ;. Compiling and Running Are Separate Steps In “Writing and Running a Rust Program”, we showed you how to run you come from a C or C++ background, you’ll notice that this is similar to gcc or clang. After compiling successfully, Rust should output a binary executable, which you can see on Linux or OSX by entering terminal. If you come from a dynamic language like Ruby, Python, or JavaScript, you may not be used to compiling and running a program being sep- arate steps. Rust is an ahead-of-time compiled language, which

Interpreted programs tend to 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 crucial for fast compilation. In many compilers compilers, 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

converted to GENERIC. I describe the structure of the frontend and the IR, issues that arise when compiling the Go language, and issues with hook- ing up any frontend to the gcc middle-end. 1 Introduction be static to this package. So gccgo must build all such tables here, in case it needs them when compiling some other package. 12. Gccgo walks the IR looking for all uses of && and || and converts them package name, the name of the initial- ization function, and the package priority. This is used when compiling the main package to call all required initialization routines. The list is inclu- sive, in that
