编译器一般构成 传统的编译器通常分为三个部分,前端(frontEnd),优化器(Optimizer)和后端(backEnd). 在编译过程中,前端主要负责词法和语法分析,将源代码转化为抽象语法树;优化器则是在前端的基础上,对得到的中间代码进行优化,使代码更加高效;后端则是将已经优化的中间代码转化为针对各自平台的机器代码。 GCC GCC(GNU...

In C++11, nullptr is only convertible to bool as a direct-conversion; for example, when you initialize a bool by using a braced initializer-list. This restriction was never enforced by MSVC. MSVC now implements the rule under /permissive-. Implicit conversions are now diagnosed as ill-formed...
