源程序相对于一个运行平台来说是不可识别的,但当编译器将源程序编译成为这个平台所能够识别的目标语言以后,程序就可以在这个平台上运行了。Java虚拟机是一个平台,DOS 和Windows也是平台。 看来以上三个概念,就明了了,为什么我们编写程序的时候,我们甚至可以只用一个简单的记事本就可以搞定,但是要运行的时候,就需要...

It has a wide range of functionalities like Project templates, project management, debugger interface, code completion, multiple compilers, and customized user interface. It is written in C++ Programming language. It involves the direct compilation of code and is easy to run. ...
The OpenJDK JVM has two Just-In-Time compilers, C1 and C2. C2 is a compiler that applies many optimizations to produce a very efficient compiled version of the program. This blog post series presents an improvement that we contributed to C2 scalar replacement optimization. But before we delve...
As we will see, the Tiered Compilation process in HotSpot is a very elaborate process, but the idea is still the same one that we discussed in the previous section: use the best tool for the job. HotSpot has 2 compilers, C1 (source here) and C2 (source here), and an interpreter. Th...
