Dear PL/1 followers,

This is the sixth code drop of the GCC front-end for the PL/1 programming language.

PL/1 for GCC is released under the terms of the GNU Public License; version 2.

Changed in pl1gcc v0.0.6: - Keep track of token locations - Removed homegrown twopass scanning and parsing - Added new testone test script file - Fixed syntax: dcl a(*) BLKSIZE '(' NUM ')' allow UNAL as abbrev for UNALIGNED *PROCESS ignored by scanner PUT DATA/SKIP/PAGE GET DATA/SKIP/PAGE

For a complete changelog look at the README file.

Just to summarize. The pl1gcc project is an attempt to create a native PL/1 compiler using the GNU Compiler Collection. The project is looking for more people to join the development or testing. If you have any spare time, please do contact us and join the fun.

The project started up with a simple standalone scanner and parser, that subsequently got integrated into the GCC build system by using the sample language Treelang as a starting point. Current development concentrates around the infrastructure necessary to recognize and support pl/1 and to prepare for the actual code generation.

After more testers and developers joined in, several syntax issues have been fixed. Special thanks to Rob Watson, and also for the sample code dating all the way back to 1969. If you do try the compiler on some of your own code, and do not get an OK back from the compiler, please let us know, so we can adapt the grammar accordingly. Actually even if you do get an OK back it would be nice to know the compiler worked for you.

Have fun

The GCC PL/1 Team.
