another exception handling question.... (was Re: trying to glue Modula-3 onto egcs table based exception handl ing support)

[Marc Fiuczynski]

I got regular try-except blocks to work from my Modula-3 front-end with
the table-based exception handling support in gcc 2.95.2.

What I need to do now is provide support for try-finally statements.  A
try-finally block looks like this:
TRY
  guarded statements
FINALLY
  final statements
END

And the "final statements" will always be executed, regardless if an
exception was raised or not in the "guarded statements" above.

I am trying to figure out what to use from except.c.  It seems that
add_partial_protect() and end_protect_partials() are kinda what I want,
which are used for "cleanups".   However, it seems that these cleanups
are also only executed in an exceptional situation, which is not exactly
what I want.  Further, I'd like the code that gets generated for the
"final statements" to be immediately follow the guarded statements.  I
don't really see the right stuff in except.c to handle this.

Any comments/hints/feedback appreciated.

Cheers,
Marc
