The compiler tool chain is one of the largest and most complex components of any system, and increasingly will based on open source code, either GCC or LLVM. On a Linux system only the operating system kernel and browser will have more lines of code. For a commercial system, the compiler has to be completely reliable—whatever the source code, it should produce correct, high performance binaries.
So how much does producing this large, complex and essential component cost? Thanks to open source not as much as you might think. In this post I provide a real world case study, which shows how bringing up a new commercially robust compiler tool chain need not be a huge effort. Read More
