setjmp, sigsetjmp, siglongjmp,_setjmp

Hello, everyone,
I have a question here.
Do setjmp(), sigsetjmp(), siglongjmp(), and _setjmp() in NetBSD save the 
content of fpu registers? It appears that in <setjmp.h>, setjmp_buf[] has 
only 18 long type, which I think corresponding to D0-D7, A0-A7, SR and 
PC. So how can I save the fpu registers?
