Correct SPARC stack alignment
Even after the ucontext_t and makecontext patches, Solaris/SPARC execution
tests
were still FAILing (seem to have lost the notes about the details ;-().
However,
I found that stack alignment was less than the SPARC ABI requires, i.e.
doubleword
alignment (also cf. sparc/sparc.h (SPARC_STACK_ALIGN)).
The attached patch fixes that. However, I've been lazy and always use the
existing
16-byte alignment code, although strictly speaking 32-bit SPARC only needs 8
bytes.
