pl1gcc-0.0.12

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

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

This is mostly a technical release, with some visible user changes. Most notably, the compiler output will now show the compiler options, and a message indicating the number of successfully parsed statements, and further show syntax errors as well.

There is still no code generation taking place, so don't run out and uninstall your production PL/I compiler just yet :-)

Please inform us about any syntax errors that might occur so we can check if the error is in the pl1gcc parser, and not in your code.

Changes in v0.0.12:

• Scanner and parser are now reentrant
• Synchronized with gcc version 4.2-20060715
• Improve internal documentation of functions
• Parsing of procedures and their parameters
• Stop compiling at first error
• Make compiler output more user friendly

Changed syntax in v0.0.12:

• Fixed error when %INCLUDE filename was not found
• Ignoring hex character 0x1A (ctrl-z, EOF)
• Accept but ignore the following preprocessor statements
  • %SKIP
  • %PAGE
  • %PRINT
  • %NOPRINT

Changed semantic checks in v0.0.12:

• Error message if procedure name is already defined
• Error message if %INCLUDE cannot be resolved
• Error message if an unknown character is met
• Error messages by bison: Syntax error ...

What is pl1gcc ?

The pl1gcc project is an attempt to create a native PL/I compiler using the GNU Compiler Collection.
The project is looking for more people to join the development and testing. If you want to help speed up the development of a free PL/I compiler please do contact us and join the fun.

Looking ahead

If you know of a PL/I project that should be compilable by the pl1gcc compiler, please get in touch with us and we'll see if we can accommodate it. The code does not have to be covered by GPL.

And finally remember to have some fun
