pcc - The Portable C Compiler
- Description:
The compiler is based on the original Portable C Compiler by Stephen C.
Johnson, written in the late 70's. Even though much of the compiler has been
rewritten, some of the basics still remain.
PCC debuted in Unix Version 7 and replaced the DMR compiler (Dennis Ritchie's
original C compiler) in both System V and the BSD 4.x releases. Some history
about pcc is in the A History of UNIX before Berkeley: UNIX Evolution:
1975-1984 and in the Evolution of C.
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 Luleå University of Technology (LTU).
Caution: the compiler is still undergoing heavy development.
