Modified files:
lib/libc/sparc64/gen _setjmp.S setjmp.S
Log:
Rewrite longjmp() and _longjmp() to directly restore the saved frame,
instead of unwinding the call stack. This makes them usable to switch
stacks, e.g. for libc_r.
Do not save the frame pointer in setjmp() and _setjmp(), it is not needed
any more.
Rename _longjmp() to ___longjmp(), with a weak alias to _longjmp(), like
the other architectures did.
