Wanting to make sure I'm reading the requirements correctly.


Looks like this routine only needs to save the link register and env, call
setjmp then restore the link register and env followed by the tail call.


Hexagon was out of date so I did this:


.balign 4

.type sigsetjmp,@function


        // if savemask is 0 sigsetjmp behaves like setjmp


                p0 = cmp.eq(r1, #0)

                if ( jump:t ##setjmp



                memw(r0+#64+4) = r16  // save r16 in __ss[0]

                memw(r0+#64)   = r31  // save linkregister in __fl

                r16 = r0


                call ##setjmp


                r0  = r16             // restore r0

                r31 = memw(r16+#64)   // restore linkregister

                r16 = memw(r16+#64+4) // restore r16 from __ss[0]


.hidden __sigsetjmp_tail

        jump ##__sigsetjmp_tail


.size   sigsetjmp, .-sigsetjmp
