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.
