>From bug #13905 which I posted I'd like to add the following:
This idea of Dirk's is good but I think he's coming at it the wrong way. Instead
of labouriously specifying things as hidden individually and hoping to not
forget any, the *default* should be hidden and you specify things as exported
individually - here if you forget you get a link error.
Not uncoincidentally, I'm wishing to leverage the same semantics as Windows so
that the macros commonly used on cross-platform applications merely need to be
redefined from __declspec(dllexport) to __attribute__ ((visibility("export"))
and no further code changes are required.
To allow this to happen, GCC would need an extra command line option to set the
default visibility of all symbols:
-fvisibility=external
-fvisibility=default
-fvisibility=protected
-fvisibility=hidden
-fvisibility=internal
These are chosen for compatibility with Intel's C++ compiler which already
offers the ability to mark all symbols as default non-exported in ELF output.
Why this approach is better than Dirk's: much cleaner ELF images output. Faster
dynamic linking times as less symbols are exported. Much more scope for GCC to
optimise object files as it now knows what RTTI info it can discard as well as
improved COMDAT folding etc.
I in particular suffer from this as GCC generates binaries nearly twice as big
than MSVC for identical code :( (I think it's the RTTI info for all the
templates plus not being able to COMDAT fold most of the symbols)

Niall, it seems you didn't understand the purpose of the bugreport. The major
problem right now is that you cannot change the visibility for all members
of a class with one statement from default.
Wether that is "default == hidden" and "overwrite == visible" or
"default == visible" and "overwrite == hidden" doesn't matter, since both
variants need the very same level of support in the compiler, which
currently does not exist.
Of course our long term plan is it to be able to default to
visibility==hidden, but right now thats not possible because of a missing
feature which this wishlist item requests.
I don't actually want to argue with you which default visibility is right
or wrong. If you want to have that changed, then please open a separate
bugreport, because it is not the topic of this one :)

No I absolutely agree with that.

Precisely my point.

What I was trying to bring was the need for maintaining a compatible syntax with
MSVC eg; making it "class Foo __attribute__ (("hidden"))" would banjax the tens
of millions of lines of code which could be converted to use your feature by
adjusting some macro definitions. Now you seem to know this because of how you
framed your example, but I have noticed an alarming negativity in this list
about interoperability features with MSVC just because it's a Microsoft product.

My original bug report was #13905 which I was told was too similar to yours and
they closed it (many times). I did point out on that bug that what I proposed
slightly exceeded what you did, but they told me go post an outline of the
differences to this bug report, which I did.
My apologies if this didn't come across as I intended it. BTW I feel that
default visibility is the right of each user to choose, I feel tools are there
to create choice and flexibility and thus both avenues should be available. Free
software is about being better than proprietary and a large part of that is
being interoperable with him when he is trying to wreck us with dirty tactics!

Niall

Can you change this line in your patch:
+ current_class_stack[current_class_depth].visibility = VISIBILITY_DEFAULT;
Make this:
+ current_class_stack[current_class_depth].visibility =
compilation_unit_visibility;
... and then declare where the command line args are parsed a:
static enum symbol_visibility compilation_unit_visibility = VISIBILITY_DEFAULT;
This makes it easier to add the -fvisibility=X command line switches to GCC
later on.

Niall

This is to let you all know that I have taken Brian Ryner's patch and used it to
implement a further patch against GCC v3.4 CVS adding the -fvisibility
functionality I previously described with appropriate documentation patching
too. I am currently testing my patch though I should be finished by tonight.
Using my new patch, I have reduced the dynamic symbol table of my library,
TnFOX, from 16342 symbols down to 9590 with no special measures and no problems.
Furthermore the binary size has dropped as my patch marks many more symbols as
local and thus their access code can be optimised.
I am just about to embark on compiling the Boost.Python based python bindings
for TnFOX. They previously had >250,000 symbols and took six minutes for
anything linked against them to load - even after applying a filtering version
script, I could only get it down to ~76,000 which at least linked in less than
ten seconds. With my new GCC, I am expecting to reduce this to less than 1000
symbols with a substantial reduction of binary size (it's currently 130Mb) as
lots of RTTI can be elided.
I'll get back to you when I have built the bindings (it takes nine hours).
Cheers,
Niall

Please find attached a patch against GCC CVS 20040324 adding the -fvisibility
command line arg, documentation for the same, class/struct visibility setting
and improved symbol locality setting which gives better code quality.
I have tested this against the regression suite and the test results were
identical to an unpatched version.
I have also compiled my library and Boost.Python based python bindings with
excellent success. My BPL bindings were ~21Mb smaller and load in seconds rather
than minutes. The exported symbol table dropped from >200,000 symbols to only
~19,000 with doing nothing other than using -fvisibility=hidden and
__attribute__ ((visibility("default"))) wherever __declspec(dllexport) was being
used on MSVC. I am very happy with the results.
Cheers,
Niall

I chose -fvisibility because that's what Intel's C++ compiler for Linux uses.
Never used a Sun box in anger, so I'm not very familiar with that platform.

I posted a new patch here based on earlier review comments:
http://gcc.gnu.org/ml/gcc-patches/2004-04/msg00240.html
I like the idea of moving forward on -fvisibility as well, but we need a way to
address the fact that current DSO header files on unix don't normally specify
default visibility. Intel's compiler has additional options, such as:
-fvisibility-default=<file>
Space separated symbols listed in the <file> argument will get
visibility set to default
This type of file could be generated by running nm over the shared libraries you
plan to link against. Unfortunately I haven't been able to figure out how to
get the symbol name for a decl (exactly as it would be output in the assembly),
to compare against a list of symbols generated with nm.
Niall, I assume you just changed the relevant system headers to specify default
visibility? I think we'd be causing a lot of headaches if we tried to force all
library maintainers to do this.

I'll see if your revisions can offer any suggestions to what I did to your
patch. However, I substantially changed how symbol visibility is applied which I
think does depend on the class stack eg; if a class is hidden but contains a
class which is default but that class contains another class which is hidden.
I also changed how visibility is taken into account when making a symbol local
which lets the compiler and optimiser work better. Basically anything which
doesn't have default visibility is made local. I also made all inlineable code
always the -fvisibility setting no matter what and a few other things.

I don't believe this can be done past what the GNU ld version scripts already
do. DSO interface specification is something which requires a human to manually
graft through the interface definitions and do the needful. Things like glibc
show what I mean and anyone from a Windows background will also know what I
mean.
This isn't as bad as it sounds. Anything which can run on Windows already has
the macro support code. If you get this feature into GCC now, code will start
moving in the right way anyway. It's simply the right way to go, especially for
template heavy C++. I wouldn't sweat trying to make the perfect solution right
here and now, if we get the feature out there the feedback will guide us the
right way.

No, I modified the function which creates a new decl to simply set the
visibility to whatever the command line arg specified. This causes all decls to
be that visibility by default which is just what we want. There are no knock-on
effects of this patch on any other part of GCC, I took special care to ensure
this. The patch should just drop in will no ill side effects.
I put together a web page explaining why this patch is such a good idea at http:
//www.nedprod.com/programs/gccvisibility.html. However Ulrich Drepper got there
well before me at http://www.nedprod.com/programs/dsohowto.pdf.
Cheers,
Niall

handle_visibility_attribute to be called for types.
(handle_visibility_attribute) When given a type, set the visibility
bits on the TYPE_NAME. When given a decl, don't set no_add_attrs
so that we can check later whether the attribute was present. Added
warning if attribute applied to non class type.
* c-decl.c (diagnose_mismatched_decls): Updated rules for merging
decls and checking that they are consistent.
* common.opt: Added -fvisibility.
* c.opt, c-opts.c: Added -fvisibility-inlines-hidden.
* c-pragma.h, c-pragma.c: Added handle_pragma_visibility().
* flags.h, tree.h: Added assorted support defines for overall patch
* opts.c: Added parsing support for -fvisibility.
* tree.c (build_decl): Set visibility for all decls to be whatever

* c-common.c (c_common_attribute_table): Allow
handle_visibility_attribute to be called for types.
(handle_visibility_attribute) When given a type, set the visibility
bits on the TYPE_NAME. When given a decl, don't set no_add_attrs
so that we can check later whether the attribute was present. Added
warning if attribute applied to non class type.
* c-decl.c (diagnose_mismatched_decls): Updated rules for merging
decls and checking that they are consistent.
* common.opt: Added -fvisibility.
* c.opt, c-opts.c: Added -fvisibility-inlines-hidden.
* c-pragma.h, c-pragma.c: Added handle_pragma_visibility().
* flags.h, tree.h: Added assorted support defines for overall patch
* opts.c: Added parsing support for -fvisibility.
* tree.c (build_decl): Set visibility for all decls to be whatever
is in force at that time.
* varasm.c (default_binds_local_p_1): Reworked logic determining
when to make a symbol locally bound.
* doc/invoke.texi: Added documentation for -fvisibility and
-fvisibility-inlines-hidden.

* class.c (check_field_decls): Apply hidden visibility if
-fvisibility-inlines-hidden and inlined unless otherwise specified
(build_vtable): Set vtable visibility to class visibility.
(check_field_decls): Default static member visibility to class
visibility.
(check_methods): Default method visibility to class visibility.
* cp-tree.h: Added CLASSTYPE_VISIBILITY and
CLASSTYPE_VISIBILITY_SPECIFIED macro.
* decl.c (duplicate_decls): New logic for merging definition decls
with declaration decls. Added ignore & warning when non default
applied to global operator new or delete.
* method.c, optimize.c, rtti.c: Added setting of VISIBILITY_SPECIFIED
wherever VISIBILITY was changed
* rtti.c (get_tinfo_decl): Set typeinfo visibility to class
visibility.
(tinfo_base_init): Set typeinfo name visibility to class visibility.
