I have "upgraded" the Poly/ML site on SourceForge (there didn't seem to be any choice) and as a consequence the subversion site has changed. Anyone who is following Poly/ML SVN will need to change to the new site. For trunk this is svn checkout svn://svn.code.sf.net/p/polyml/code/trunk polyml and for the 5.5 fixes branch svn co svn://svn.code.sf.net/p/polyml/code/fixes-5.5 polyml
I am currently working on the stages of the compiler that process and optimise the intermediate code. These are parts of the compiler that haven't been looked at for a very long time and some of it was obviously translated automatically from my original Poly code back in the 1980s. I tend to commit changes fairly regularly rather than accumulate a long set of changes and commit all at once. This does mean that things could be broken and only fixed by a later commit but it makes it much easier to find a bug if it shows up much later.
Season's greetings and best wishes for the New Year, David
