        src/lib/libc/arch/sparc64/gen: longjmp.c setjmp.S sigsetjmp.S
 
 Log Message:
 Fix offsets used in the assembly code to save global registers into a
 jmp_buf, add a compile time assert to catch this kind of divergence
 in the C code.
 Move the fixed "%npc = %pc + 4" computation to longjmp, this frees
 the sigcontext sc_npc value. Use this space to save the savemask
 for siglongjmp (we have run out of space behind the globals).
 Fixes the tests/lib/libc/setjmp/t_threadjmp tests, and also hopefully
 fixes PR port-sparc64/44902.
