The siginfo changes (and resulting deprecation of sigreturn)
have caused a major backward compatibility problem for
The following platforms use __sigreturn14 to implement their
These platforms no longer having working setjmp/longjmp if
COMPAT_16 is not in the kernel configuration.
Remove COMPAT_16 from your kernel, and attempt to use setjmp/longjmp
on any of the architectures listed above.
Problem was noticed by code inspection.
The right thing to do is to version the setjmp/longjmp family
of functions again (for ALL architectures) and re-implement using
using getcontext()/setcontext(). Perhaps the lightweight versions
of these functions from libpthread could be integrated into libc
for part of the implementation.
