Just continue when you hit the _mesa_test_os_sse_exception_support() function. It's a normal part of start-up. We found that the only reliable way to detect SSE support (both CPU-wias and OS-wise) is to try an SSE instruction and see if an exception is raised. -Brian ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
