| H A D | fpu.h | diff 238598 Wed Jul 18 13:46:03 MDT 2012 kib On AMD64, provide siginfo.si_code for floating point errors when error occurs using the SSE math processor. Update comments describing the handling of the exception status bits in coprocessors control words. Remove GET_FPU_CW and GET_FPU_SW macros which were used only once. Prefer to use curpcb to access pcb_save over the longer path of referencing pcb through the thread structure.
