pl1gcc newsFebruary 23rd, 2005

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

Version 0.0.9 marks yet another milestone for the PL/I front-end project, because a much larger subset of the PL/I language can now be parsed using only flex and bison.

If you are testing the PL/I compiler, please inform us about any syntax errors that might occur. It suffers to send the offending line of code.

Changes in v0.0.9:

  • Added preliminary syntax diagrams, thanks to ebnf2ps and latex2html
  • Setup a newsgroup pl1gcc-development@lists.sourceforge.net
  • Fixed syntax error in YYLLOC_DEFAULT macro
  • Use the gcc-4.0-core snapshot
  • Revised the DECLARE statement
  • Unification of signal-conditions and on-conditions
  • Allow '*' as filler/padding in structure
  • List of condition commalist for ON and REVERT statements
  • Allow '_' and ' ' in numeric constants for improved readability
