Sorry, but we still need to discuss what programming model you intend
to support before I will consider looking at diffs.
Currently, on i386, GDB supports a fully flat 32-bit model, with one
small exception on platforms that support thread-local-storage. In
that model you can assume that all the segment bases are 0 except for
%gs. If that's all that people are interested in, I don't think we
should bother with segment bases for %cs, %ds, %es, %fs and %ss.
If people want to support fully segmented memory in GDB, then what you
propose is probably not enough, at least not for 32-bit mode.
