It would be good, error reporting-wise, to be able to signal which
function should be used instead of a deprecated one. GCC 4.5 added an
optional "message" payload to the deprecated attribute, so that:
void f1 (void) __attribute__((deprecated("Use f2 instead")));
Will expand to:
warning: f1 is deprecated: Use f2 instead
Instead of just printing:
warning: f1 is deprecated
Since we already have a G_GNUC_DEPRECATED macro we should provide a
G_GNUC_DEPRECATED_FOR macro defined as:
G_GNUC_DEPRECATED_FOR(bar)
Which would expand the deprecation message to "Use bar instead"
automatically. The deprecation message should probably be similar
to what we use in gtk-doc to match up with the documentation.

* glib/gmacros.h (G_STRUCT_OFFSETOF): Use offsetof instead of
__builtin_offsetof, for icc's sake. Proposed by Hrvoje Niksic.
svn path=/trunk/; revision=7811
2008-10-29 16:11:14 Tim Janik <timj@gtk.org>
* glib/gmacros.h: added G_PASTE() and G_STATIC_ASSERT(), based on
patches by Christian Persch and Christian Dywan. Fixes:
Bug 558381 - Add support for compile time assertions
svn path=/trunk/; revision=7633

Bug 551228 – G_STRFUNC on recent Sun compiler should be expanded to
__func__ rather than '???'
* glib/gmacros.h: Don't use glibconfig.h defines in gmacros.h,
as the comment up top says. Instead look at __STDC_VERSION__.
Problem reported by Lin Ma.

* glib/gmacros.h: implement G_STMT_START and G_STMT_END with
do{}while(0), which is believed to be widely portable, fixes:
Bug 519026 - G_STMT_START/G_STMT_END test a non-existent preprocessor symbol

2008-05-05 Michael Natterer <mitch@imendio.com>
* glib/glib.h: #define __GLIB_H_INSIDE__ around including
everything.
* glib/*.h: check for that define instead of __G_LIB_H__ if
G_DISABLE_SINGLE_INCLUDES is defined.
* glib/gdatasetprivate.h: #include <glib.h> instead of
<glib/gdataset.h>
svn path=/trunk/; revision=6875
2008-03-14 Michael Natterer <mitch@imendio.com>
* glib/*.h: make it possible to disable single-file includes by
defining G_DISABLE_SINGLE_INCLUDES when building against GLib.
Approved by Tim Janik.
* glib/glib.h: include <glib/gslice.h>.
* glib/gi18n.h
* glib/gi18n-lib.h
* glib/gprintf.h: include <glib.h> so the above works when these
files are included without including <glib.h> first.

g_try_realloc.
2005-11-28 Matthias Clasen <mclasen@redhat.com>
Fix G_STMT_START / G_STMT_END on Solaris. (#321972,
Andrew Paprocki)
* configure.in: Check whether do { } while (0) works.
* glib/gmacros.h: Use do { } while (0) for G_STMT_START /
G_STMT_END if it works.
2004-08-10 Matthias Clasen <mclasen@redhat.com>
* glib/gmacros.h: Remove G_GNUC_INTERNAL from here.
* configure.in: Check whether the visibility attribute
works and define G_HAVE_GNUC_VISIBILITY and
G_GNUC_INTERNAL in glibconfig.h correspondingly.
2004-08-02 Matthias Clasen <mclasen@redhat.com>
* glib/gmacros.h: Add a G_GNUC_INTERNAL macro to mark function
declarations as internal and avoid PLT indirections for
them. (#145465, Arjan van de Ven)
* glib/gunicodeprivate.h:
* glib/gthreadinit.h:
* glib/gmessages.h:
* glib/gdebug.h:
* glib/gconvert.c: Use G_GNUC_INTERNAL for _g_charset_get_aliases(),
_g_debug_init(), _g_log_fallback_handler(), _g_mem_thread_init(),
_g_messages_thread_init(), _g_convert_thread_init(),
_g_rand_thread_init(), _g_main_thread_init(), _g_atomic_thread_init(),
_g_mem_thread_private_init(), _g_messages_thread_private_init(),
_g_utf8_normalize_wc() and _g_unichar_combining_class().
* glib/gatomic.c: Include gthreadinit.h here to see the declaration
for _g_atomic_thread_init().
Sat Mar 13 23:30:53 2004 Owen Taylor <otaylor@redhat.com>
* glib/gmacros.h (G_STMT_START): Add __extension__
to G_STMT_START to quite gcc -pedantic. (#131899,
Olivier Biot)
Thu Dec 11 10:31:21 2003 Manish Singh <yosh@gimp.org>
* glib/gmacros.h: change #elif with no expression to #else in
G_STRFUNC definition. Thanks to Damien Carbery, fixes#129101.
Thu Nov 27 17:04:08 2003 Tim Janik <timj@gtk.org>
* glib/gstrfuncs.c (g_strconcat): handle NULL arguments
gracefully.
* glib/gmacros.h: defined G_STRFUNC, which (pretty) prints the
current function (since G_STRLOC and G_GNUC_*FUNCTION became
unusable with gcc-3.0).
Tue May 27 19:56:35 2003 Owen Taylor <otaylor@redhat.com>
* glib/gmacros.h: __PRETTY_FUNCTION__ was made a non-token
before gcc-3.0.0 for C++. (Fix from Martin Kretzschmar,
#113797)
Thu Dec 12 14:58:55 2002 Manish Singh <yosh@gimp.org>
* configure.in: pull in trio if host printf doesn't have a known
way of printing 64-bit ints.
* glib/gmacros.h: remove extra whitespace at the end
* glib/gscanner.c (g_scanner_unexp_token): use G_GUINT64_FORMAT
instead of hardcoding "%llu"
* tests/testglib.c: remove obsolete conditionals using G_HAVE_GINT64,
we always have it now.
* tests/type-test.c: same as above, and for G_G[U]INT64_FORMAT as
well.
* glib/gmessages.h: Use G_LIKELY without surrounding parentheses
in g_assert() and g_return_[val]_if_fail() so that we always trigger
the gcc warning about "assignment used as truth value".
* glib/gmacros.h: Always put parentheses in G_LIKELY and G_UNLIKELY.
* glib/gmessages.h (g_assert):
(g_return_if_fail):
(g_return_val_if_fail): Remove the (no longer effective) empty
if-branch.
* glib/gmacros.h: Change the definition of G_LIKELY, so that
g_return_if_fail() and friends still trigger a gcc warning if
the expr is an assignment.
Fri Nov 22 09:39:09 2002 Owen Taylor <otaylor@redhat.com>
* glib/gmacros.h: Remove broken G_HIDDEN_SYMBOL
definition which wasn't supposed to be committed
at all.
* glib/gmessages.h (g_return_if_fail):
(g_return_val_if_fail): Use G_LIKELY. (#69022)
* glib/gmacros.h (G_LIKELY):
(G_UNLIKELY): New macros for hinting the compiler about the
expected result of expressions. For gcc 3.x, define these
using __builtin_expect. (#69022)
* glib/tmpl/macros_misc.sgml: Document G_LIKELY, G_UNLIKELY.
* glib/glib-sections.txt: Add G_LIKELY, G_UNLIKELY.
Mon Jan 28 17:56:10 2002 Owen Taylor <otaylor@redhat.com>
* glib/gmacros.h: Only use __FUNCTION__, __PRETTY_FUNCTION__ for
G_GNUC_FUNCTION, G_GNUC_PRETTY_FUNCTION, G_STRLOC when __GNUC__ <
3, since in 3.0.3 the semantics of these functions were changed in
an incompatible way. (#69097)
The following patch corrects some function attributes. (#61780)
* glib/ghash.h (g_int_equal, g_int_hash): These are not const.
* glib/glibintl.h (_glib_gettext): Add G_GNUC_FORMAT(1).
* glib/gmacros.h: Use reserved symbols in function attribute macros.
The following patch avoids manual printf()-format parsing
if a C99-conforming vsnprintf() is available. (#55106)
* acinclude.m4 (AC_FUNC_VSNPRINTF_C99): New macro to test for a
C99 conforming vsnprintf.
* configure.in: Use AC_FUNC_VSNPRINTF_C99.
* glib/gmessages.c (g_printf_string_upper_bound): Use C99 vsnprintf().
Wed Jun 20 12:00:54 2001 Owen Taylor <otaylor@redhat.com>
Changes for 64-bit cleanliness, loosely based on patch
from Mark Murnane.
* gconvert.c (g_convert/g_convert_with_fallback): Remove
workarounds for since-fixed GNU libc bugs. Minor
doc fix.
* gconvert.[ch]: Change gint to gsize/gssize as
appropriate.
* gconvert.c (g_locale/filename_to/from_utf8): Fix incorrect
computation of bytes_read / bytes_written.
* gfileutils.[ch] (g_file_get_contents): Make length
out parameter 'gsize *len'.
* ghook.c (g_hook_compare_ids): Don't compare a
and b as 'a - b'.
* gmacros.h (GSIZE_TO_POINTER): Add GPOINTER_TO_SIZE,
GSIZE_TO_POINTER.
* gmain.c (g_timeout_prepare): Rewrite to avoid
overflows. (Fixes bug when system clock skews
backwards more than 24 days.)
* gmarkup.[ch]: Make lengths passed to callbacks
gsize, length for g_markup_parse-context_parse(),
g_markup_escape_text() gssize.
* gmessages.[ch] (g_printf_string_upper_bound): Change
return value to gsize.
* gmessages.c (printf_string_upper_bound): Remove
a ridiculous use of 'inline' on a 300 line function.
* gstring.[ch]: Represent size of string as a gsize,
not gint. Make parameters to functions take gsize,
or gssize where -1 is allowed.
* gstring.c (g_string_erase): Make
g_string_erase (string, pos, -1) a synonym for
g_string_truncate for consistency with other G*
APIs.
* gstrfuncs.[ch]: Make all functions taking a string
length, take a gsize, or gssize if -1 is allowed.
(g_strstr_len, g_strrstr_len). Also fix some boundary
conditions in g_str[r]str[_len].
* gutf8.c tests/unicode-encoding.c: Make parameters that
are byte lengths gsize, gssize as appropriate. Make
character offsets, other counts, glong.
* gasyncqueue.c gcompletion.c
timeloop.c timeloop-basic.c gutils.c gspawn.c.
Small 64 bit cleanliness fixups.
* glist.c (g_list_sort2, g_list_sort_real): Fix functions
that should have been static.
* gdate.c (g_date_fill_parse_tokens): Fix extra
declaration that was shadowing another.
* tests/module-test.c: Include string.h
Mon Jun 18 15:43:29 2001 Owen Taylor <otaylor@redhat.com>
* gutf8.c (g_get_charset): Make argument
G_CONST_RETURN char **.
2000-11-21 Havoc Pennington <hp@pobox.com>
* gmacros.h: Provide G_CONST_RETURN which is 'const' by default,
and nothing when G_DISABLE_CONST_RETURNS is defined.
