I'm willing to see if I can resolve the build problems under HP-UX 10.20. As far as the code generated by GCC and the debug information, there is almost no difference between HP-UX 10 and 11. We have weak symbol support and and a different way of running initializer, but that's it. I don't particularly care about HP compiler support. There's still a fair number of PA 1.1 workstations running. They were really the peak in PA-RISC technology and they have proved to be extremely reliable. On the other hand, I agree that there isn't much point in spending a lot of effort on the machines. The 10.20 machine that I use for GCC testing is mainly used for support of a space experiment that probably will be supported by NASA and ESA through to the end of 2007. I'm not particularly interested in moving the software and licenses to a newer machine. So, I will probably try to keep the machine operational until the end of the mission. Anyway, I probably will support 10.20 in GCC until 3.5 is released. I think if Michael can improve gdb under HP-UX 11, we would also see benefits under HP-UX 10. Carlos O'Donell has made a New Years resolution to spend a good portion of his time on gdb for hppa-linux. He has done an excellent job in improving glibc. Matthew Wilcox has offered a bounty for a gdb maintainer for hppa-linux: . I managed to build gdb 6.0 under hppa-linux starting from the debian patches. It only took a couple of small patches. My initial impression is that it works better than 5.3, particularly with ada code. I did have a problem with an undefined dwarf2 DIE. In summary, I'm hopeful that the gdb support for PA-RISC can be improved in 2004. Dave -- J. David Anglin dave.anglin@nrc-cnrc.gc.ca National Research Council of Canada (613) 990-0752 (FAX: 952-6602)
