It too early to tell but I have no objections to discussing options.
Are you looking to share source files? This seems like low value because
the files tend to be small and the only difference is the dg-*
directives. I don't know enough about the DejaGnu macros to even guess
at what this might entail.
So far the sharing it is mostly one way (./i386/ -> ./powerpc/) but if I
find cases that requires a new dg test and might also apply to ./i386/ I
be willing to share that with X86.
