Richard, this was the latest version of the patch:

Are you OK with my clean-up of the presumably dead function names,
or would you like to keep the quirks in special_function_p for now
and just remove ECF_NORETURN and ECF_LEAF?
The only worry I have left is we're not catching _ prefixed savectx,
vfork & getcontext (the the latter two being the important ones).
Various ports still use USER_LABEL_PREFIX, so those symbols might be
showing up as _vfork & friends.
That might just be an oversight (using name instead of tname in the
simplified conditional).
no, that is actually intentional.
OK. Thanks for clarifying.
If name would contain USER_LABEL_PREFIX then special_function_p would
already have been broken, and that would need to be fixed as well.
We need to handle __sigsetjmp, and that would not work with
one extra underscore.
I try to keep compatible to what is used in the header files of
glibc and newlib.
glibc defines setjmp to _setjmp, and sigsetjmp to __sigsetjmp.
and newlib does not do that.
Thus we actually need to handle these names:
setjmp
_setjmp
sigsetjmp
__sigsetjmp
vfork and getcontext are no defines, so I don't see why
we should match more names than absolutely necessary here.
OK. I understand and agree.
