《CPython Internals》阅读笔记：p61-p75

《CPython Internals》学习第 4 天，p61-p75 总结，总计 15 页。

一、技术总结

1.编译器类型

(1)self-hosted compiler

Self-hosted compilers are compilers written in the language they compile, such as the Go compiler. This is done by a process known as bootstrapping.

wiki 上写的是 self-hosting compiler， 不知道作者为什么要改成 self-hosted。

(2)source-to-source compiler

Source-to-source compilers are compilers written in another language that already has a compiler.

2.compiler-compiler

(1)定义

tools used to generate compilers。也称为compiler generator。在一些不严谨的表述中，本来应该属于 parser generator的工具也称为 compiler generator——Well first the term compiler-compiler has been degraded to include parser generators. I blame that on yacc(yet another compiler-compiler) calling itself a compiler compiler.
