摘要

文档讨论了即时编译（JUST-IN-TIME, JIT）作为下一个大趋势的潜力。JIT是在需要时进行编译，而不是像传统的提前编译（AHEAD-OF-TIME, AOT）那样在编译时完成。这一方法通过将应用程序或库视为编译器，使得编译过程更加灵活和高效。JIT技术在编译器中的应用被认为是未来发展的重要方向。

## Just-In-Time Compilation: The Next Big Thing

Just-In-Time (JIT) compilation is a technique that compiles code at the point of need, unlike traditional Ahead-Of-Time (AOT) compilation, which happens beforehand. This approach makes the application or library act like the compiler itself, offering potential performance improvements and flexibility.

**Key Points:**

1. **Definition of JIT:**
- JIT compiles code during execution, adapting to runtime conditions.
- This contrasts with AOT, where compilation occurs before execution.

2. **Authors and Context:**
- Benjamin Deane and Kris Jusiak from Quantlab Financial presented this topic at CppCon 2020.
- They propose JIT as a significant trend in compilation technology.

3. **Technical Background:**
- The discussion includes C++ translation and evaluation, referencing the P0992 proposal, which focuses on JIT within compilers.

4. **JIT in Compilers:**
- JIT's role in optimizing compilation processes and enhancing runtime performance is explored.

5. **Potential as the Next Big Thing:**
- JIT's ability to dynamically adapt and optimize code suggests it could be a future trend in software development.

In summary, JIT compilation's dynamic nature positions it as a promising advancement, potentially offering significant benefits for performance and adaptability in programming.
