- The compiler is based on the original Portable C Compiler by S. C.
- Johnson, written in the late 70's. Even though much of the compiler has
- been rewritten, some of the basics still remain.
- The intention is to write a C99 compiler while still keeping it small,
- simple, fast and understandable. Think of it as if it shall be able to
- compile and run on PDP11 (even if it may not happen in reality). But
- with this in mind it becomes important to think twice about what
- algorithms are used.
- The compiler is conceptually structured in two parts; pass1 which is
- language-dependent, does parsing, typechecking and build trees, and
- pass2 which is mostly language-independent.
- About 50% of the frontend code and 80% of the backend code has been
- rewritten. Most stuff is written by Anders Magnusson, with the
- exception of the data-flow analysis part and the SSA conversion code
- which is written by Peter A Jonsson, and the Mips port that were written
- as part of a project by undergraduate students at LTU.
