I got busybox running on ia64 today, which ended up being a lot more work then expected. On most architectures, you can use the _syscall[0-5] macros from /usr/include/asm/unistd.h, but for some silly reason that I don't understand, the ia64 developers made those macros reference a kernel symbol. Ugh. I only needed two syscalls that were not in glibc on ia64, and those I just stuck in wrapper functions which use syscall() to do the dirty work. Managed to shave off about 500bytes in the process -- even more if you include insmod.

While fixing up busybox, I fixed up uClibc's syscall support a bit by adding a few obscure syscalls also provided by glibc. Mostly kernel module related stuff. This has the nice side effect that busybox compiles vs uClibc again (the syscall adjustment had broken it).

Well, it seems that having an account here is the thing to do ... So here goes.

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.

Keep up with the latest Advogato features by reading the Advogato status blog.
