What is gccbcpl?
The
gccbcpl project is an attempt to create a native
BCPL compiler using
GCC.
The project currently exists as a simple standalone scanner and parser (along with some infrastructure), but development is now focused on a parser rewrite
before any further work on
GCC integration. We are using the active development (mainline) branch, which will be
released as
GCC
4.0. This was previously the
tree-ssa branch, which was
merged to mainline on 2004-05-13. This is being done to enable the use of the new
GCC high-level intermediate representations (GENERIC and GIMPLE) and the optimisation framework based on the
SSA form. The current development focus is based around validation of the
BCPL grammar and the replacement of the Bison parser with a recursive-descent parser.
Further work on the development of the infrastructure for
GCC integration is currently suspended.
Code will become available to download from the
gccbcpl SF project page shortly, so when you do try the parser on your own code and get
errors, please let us know, so changes can be made to the grammar if required. Actually, even if you do get a clean parse, it would be nice to know the compiler worked for you.
The project is looking for more people to join the development and help testing. If you have previous experience with
BCPL or
GCC internals, please contact us and join the project.

as the project develops will become a useful resource for users and developers of
gccbcpl. To post a message to all the list
