This changes the exception's "message" member to be a std::string.
This allows removing the stack of exception messages, because now
exceptions will self-destruct when needed.
Note that this does increase the cost of copying an exception. This
will be somewhat addressed in a subsequent patch.

This removes the basic cleanup code: make_cleanups, do_cleanups,
discard_cleanups, and friends. This code is no longer needed, as
nothing in gdb makes an ordinary cleanup. Final cleanups are still
needed.

This series removes the remaining uses of make_cleanup from the tree,
then removes make_cleanup and some related functions (but note that
final cleanups remain).
Then, it removes the TRY/CATCH macros in favor of ordinary C++ code.
Finally, it cleans up a few spots that currently use TRY/CATCH but
that are more succinctly written using SCOPE_EXIT or RAII.
Regression tested by the buildbot.

After the rewriting to use try/catch, some of the exception code is
now unused. This patch removes that code.

* common/common-exceptions.h (exception_rethrow): Don't declare.

This introduces a new bcache_up typedef, which is a unique_ptr
specialization for managing a bcache. Then, this changes various
spots to use this object, rather than manually calling bcache_xfree.
This lets us remove a try/catch that only existed to call
bcache_xfree.

This removes the remaining cleanups from coffread.c.
Tested by the buildbot. However, I don't think the buildbot really
tests these code paths, and TBH I am not sure how to do it manually.
I did manage to crash an earlier version of the patch using a mingw
.exe file, though I would have thought that was only going to test
coff-pe-read.c.
This version includes the fix provided by Joel.

SCOPE_EXIT. This could perhaps be done in a different way, but this
approach was direct and obviously correct.

Now that cleanups have been removed, TRY/CATCH can't be SJLJ-based any
more. This patch simplifies the exception handling code, by removing
the non-working variants.
Note that the "pure" C++ exception handling code is removed as well; I
think the route forward must be to change exceptions to be
self-destructing, so that try_scope_depth can simply be removed.
Some longjmp-based code remains, as it is needed to throw an exception
through readline.

To: gdb-patches; +Cc: Tom Tromey
This replaces throw_exception with "throw;" when possible. This was
written by script. The rule that is followed is that uses of the
form:
catch (... &name)
{
...
throw_exception (name);
}
... can be rewritten. It's possible (though IMO unlikely) that such a
case could be wrong, if the exception object is rewritten in the body
of the catch. (One option here might be to catch a const & instead.)

From: Tom Tromey @ 2019-02-13 21:30 UTC (permalink / raw)
To: gdb-patches; +Cc: Tom Tromey
This rewrites gdb's TRY/CATCH to plain C++ try/catch. The patch was
largely written by script, though one change (to a comment in
common-exceptions.h) was reverted by hand.

pointers with virtual methods and using unique_ptr. This allows for
the removal of some cleanups.

This removes the last cleanups from stabsread.c. Similar code in
dwarf2read.c was C++-ified, but considering that stabs are deprecated,
it seemed simpler to just change these allocations to use an obstack
and leave the data structures in place.
This patch renames field_info to stabs_field_info -- adding a
constructor here provoked a bug due to the resulting ODR violation.
gdb/ChangeLog
2019-02-13 Tom Tromey <tom@tromey.com>
* stabsread.c (struct stabs_field_info): Rename from field_info.
<list, fnlist>: Add initializers.
<obstack>: New member.
(read_member_functions, read_struct_fields, read_baseclasses):
Allocate on obstack. Don't use cleanups.

(read_baseclasses, read_tilde_fields, attach_fn_fields_to_type)

(read_struct_type): Update.

Yay!
The only comment I have is that the structure names for exceptions look a
bit awkward in code now with the mix of lower and upper case, e.g.:
try
{
e_msg = ada_exception_message_1 ();
}
catch (struct gdb_exception_RETURN_MASK_ERROR &e)
{
e_msg.reset (nullptr);
}
We could drop the 'struct' perhaps, but not sure if we could simplify the
classes a bit to something like:
struct gdb_exception_error : public gdb_exception
{
};
struct gdb_exception_quit : public gdb_exception
{
};
And use 'gdb_execption' instead of 'struct gdb_exception_RETURN_MASK_ALL',
'gdb_exception_error' instead of 'struct gdb_exception_RETURN_MASK_ERROR',
and 'gdb_exception_quit' instead of 'struct gdb_exception_RETURN_MASK_QUIT'?

This replaces a try/catch in write_gcore_file with a use of SCOPE_EXIT
instead. I find that this is simpler to understand.

That is a good point. I think I can easily update the exception
rewriter to also rename these classes. I will take a look. Plan B is
to just have a second patch to do the renaming.

Yes please. The only reason I originally named those structs that way
was to make the CATCH macro simpler to map in the C++ variant:
#define CATCH(EXCEPTION, MASK) \
} while (0); \
} \
catch (struct gdb_exception ## _ ## MASK &EXCEPTION)
We should also catch by const reference, IMO. Is there a good reason
for the non-const-ness?
Thanks,

Just conservatism on my part, but it is easy to do the experiment.

I think a second pass is fine unless its trivial to re-run the script. I
second Pedro's suggestion about trying 'const' as well.

"const" worked fine.
For the renaming I've opted for a second patch, since it was simpler to
deal with the ChangeLog this way.
I don't plan to check this in until after other things have landed and
the 8.3 branch has been made.
