No. I'd rather remove it completely. But there's Java and
Ada implications that I havn't thought through.
We don't use this switch in GNAT. Currently only setjmp/longjmp
EH, vendor-specific EH (as on Alpha) and prologue-interpretation EH (on x86)
are used for Ada. One of the things we'd like to do soon is to integrate
with the GCC mechanisms for DWARF2-based EH. One of the problems
is that documentation in this area is rather light.
In particular it would be very useful to have a high-level overview
of the provided functionality and a break-down of backend/frontend/runtime
support that is needed for the implementation.
