[SDL] [PATCH] fix FB_VideoQuit for ia64 Jesse Barnes Fri Jan 14 11:13:54 PST 2005 I noticed that on my ia64 machine when SDL_Quit was called, the machine would hang in weird ways. It turned out to be caused by a machine check in the memset() call near the top of FB_VideoQuit. Generally memset shouldn't be used on I/O regions like the framebuffer or other I/O device memory (the Linux kernel has special routines for dealing with I/O memory), so I changed the #ifdef __powerpc__ to #if defined(__powerpc__) || defined(__ia64__) and SDL_Quit now works properly. The change should probably be made unconditional though since doing one byte at a time is the only way to be portable, afaik.
