Got bored with GCC, so now I start working on GRhino. There are some unfinished code restructure to deal with timer from previous effort. The current focus is to get game load working. After this is finished then timer work can continue which enable features such as timed games and replaying saved games. The next version, GRhino 0.13.0 will be released before sending it back to shelf.

Back from travel. One of my GCC patches is approved. Need to read more on Subversion as the GCC project repository will be switched away from CVS.

GCC: Fixed a few regressions, the small bugs that require little change, no major code reorganization. The big ones are likely to be postponed until GCC 4.0 is branched off the mainline in the CVS.
kcd: Got a plan to finish intended command line and configuration file improvements for kcd and release it as version 8.0.0.
GRhino: GRhino remains on the shelf.

I am traveling next week. So no new work for about three weeks.

Work on the finishing touches for part 5 and 6 of friend class lookup patches. They are queued for GCC 4.1. No more GCC patch that will get into CVS in this year from me. So I can wrap up work summary for GCC C++ frontend this year:

  • 4.0.x patches: 26 (plus another 2 libjava patches)
  • 3.4.x patches: 11
  • 3.3.x patches: 4

Major works: Tag lookup rewrite, member class template as friend, fixing remaining template template parameter bugs. Not as many patches as in 2003 but a few much harder problems are attacked.

Fixed a bunch of GCC regressions for 4.0. Now I start to get bored, so no patch for GCC for awhile. Only a pending patch remains.

And it's time for yearly productivity summary for the year 2004: Not much work on kcd, quite a lot of GRhino improvements early of this year. Work in later months are mostly GCC.


  • Stable releases: 2 (7.6.0, 7.6.1)
  • Development releases: 2 (7.7.0, 7.9.0)
  • Major works: Regular expression, mouse handling


  • Releases: 5 (0.9.0 to 0.12.0)
  • Major works: Online help, Game History window

Part 1 to 4 of friend class injection is committed to GCC. Part 5 (name hiding, which is almost ready) and 6 (friend of class template, which still has some issues left) are very likely to be delayed until GCC 4.1. Now it's time to fix regression in preparation for GCC 4.0 release.

Finally my new Athlon64 system is setup. It's a 3200+ with 2.2 GHz. CPU and mainboards are quite in shortage and much harder to find compare to a Pentium 4 3.2E system. Got MSI K8N Neo Platinum mainboard as another MSI model is the only other choice. There is about 2x speed boost for GCC bootstrap and regression test :)

The friend class name injection work should progress a lot more but it turned out codes in libjava are relying on the current broken behavior. A patch to fix friend class usage went into libjava earlier, and now it appears I need to write a few more patches to fix friend function usage. After then, my friend class name project can proceed.

Looked at template specialization of nested class again, and just like the last time, it is returned to the shelf. :(

On the bright side, I am getting a new machine next week. It should be an Athlon64. :)


The member class as template friend patch is finally committed October 20. This lags the feature member function as template friend by almost 11 months (committed November 22, 2003). Now I am working on friend class name injection. I wonder when friend function name injection will be finished :)


Finished some friend class injection work (Patch 1 and Patch 2). Now I have to decide which issue to fix next. One is about name injection during template instantiation (Bug 4403). The other is hiding injected name (Bug 1016).

New Advogato Features

New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.
