| 1.8 |
| 25-May-2021 |
thorpej | POSIX sez:
The longjmp() function shall not cause setjmp() to return 0; if val
is 0, setjmp() shall return 1.
Fixes the _longjmp_zero and longjmp_zero test cases in the t_setjmp
test on alpha.

martin | branches: 1.7.36;
Remove clearing of ucontext_t, the only random register values now are
argument and scratch registers (which will be reloaded after return anyway).

martin | Save the GP register value and restore it on longjmp.
While formally GP is not a callee-saved register, for static linking
the link time optimization described in section 3.2.3 of the "Calling
Standard for Alpha Systems" allows the caller to rely on GP being the
value needed within setjmp() - and not restore it after return if setjmp
and the call site share a GP value.
This fixes longjmp/setjmp for statically linked programs, e.g. /rescue/csh
or the static tcsh variant from pkgsrc.
