Incremental Compiler
Incremental Compiler is a compiler which performs the recompilation of only modified source rather than compiling the whole source program.
The basic features of incremental compiler are,
- It tracks the dependencies between output and the source program.
- It produces the same result as full recompile.
- It performs less task than the recompilation.
- The process of incremental compilation is effective for maintenance.
Cross Compiler
According to a compiler, basically there exists three types of languages. Those are,
- Source Language : The application program
- Target Language : In which machine code is written.
- The Implementation Language : In which the compiler is written.
There may be a case that all these languages are different. In other words, there may be a compiler which run on one machine and produce the target code for another machine. Such a compiler is called cross compiler. Thus by using the cross compilation technique platform independency (generate on one platform and run on any platform) can be achieved.
To represent cross compiler, T diagram is drawn as follows.

For source language L the target language N gets generated which runs on machine M.
