I want a signalhandler, which splits out sigfpe to the different copro
signals. I found a linux example, which is based on the statusword field of the
sigcontext structure passed to the signalhandler set
Problem is that the linux sigcontext has a field for the floatingpoint statusword,
while the BSD sigcontext (machine/signal.h) has only two arrays of int's:
(FPU part struct sigcontext
* XXX FPU state is 27 * 4 bytes h/w, 1 * 4 bytes s/w (probably not
* needed here), or that + 16 * 4 bytes for emulators (probably all
* needed here). The "spare" bytes are mostly not spare.
*/
int sc_fpregs[28]; /* machine state (FPU): */
int sc_spare[17];
};
Does somebody know how to distille the FP statusword from this struct?
