Where is this last condition tested to be true?  The if clause where
you wanted to add SIGSEGV doesn't test that, I think.

So perhaps we need an architecture way to do such conversions.

My line of thought is that it's IMHO fundamentally wrong to push
target- or architecture-specific details into the application level of
GDB, which is what infrun.c is.  infrun.c should deal with high-level
logic of handling a stopped inferior, it should not IMHO know about
intricacies of specific targets.
