Hello, I'm part of the (sadly fairly small) community of PS2 hackers. The current cross-toolchain for the PS2 is based on GCC 3.2.3, an outdated and buggy compiler, which I have personally gotten tired of working with, so I would like to port Clang as a newer cross-compiler for the PS2. However, the PS2 has some notable quirks which make this a non-trivial task for the current compiler. It

I just tried this, but the compiler still crashes with the same error. Maybe our experiments were different. To make

Hello Paul and Simon, (Sorry - I'm not sure about the social conventions in mailing lists) Both of your answers helped me a lot! So If I understand it correctly, Clang knows what 'mips1' and 'mips5' are - but can't generate code for it? Why is it like that? I actually have a more in general questions about processors... If this is the wrong place for it, please ignore it,

Here is the syntax I am using... rsync ftp.orst.edu::pub/CPAN \\c/ftp Unable to establish a connection is the error... DaVita Inc.
