Hi, I'm trying to implement __builtin_setjmp / __builtin_longjmp for Sparc processors. I think I'm very close, but I can't work out how to issue BuildMI-type instructions to load the address of the recovery location (set in setjmp) into a register using the SETHI / OR combination. I can't see any equivalent code anywhere else in Sparc. I imagine this is similar if I try to make a
