jake 2003/04/03 10:34:05 PST FreeBSD src repository Modified files: sys/sparc64/sparc64 exception.S swtch.S Log: Add support for saving and restoring kernel floating point state. The state will be saved if we context switch as a result of an interrupt which occured while using the floating point registers in the kernel (which actually can't happen right now). This allows fp disabled traps in the kernel, which normally shouldn't happen, so make sure the trapping code is what we expect it is.
