The -fstack-protector-strong used in many distributions by default has a
rather drastic slowdown of the fast path in generated _get_type()
functions using G_DEFINE_* macros. The amount can vary by architecture,
GCC version, and compiler flags.
To work around this, and ensure a higher probability that our fast-path
will match what we had previously, we need to break out the slow-path
(registering the type) into a secondary function that is not a candidate
for inlining.
This ensures that the common case (type registered, return the GType id)
is the hot path and handled in the prologue of the generated assembly even
when -fstack-protector-strong is enabled.

The existing implementation was completely incorrect (despite the fix in
commit 566e64a66) — it always compared GVariants by pointer, rather than
by value.
Reimplement it to compare them by value where possible, depending on
their type. The core of this implementation is g_variant_compare(). See
the documentation and tests for further details of the new sort order.
This adds documentation and tests.

This was showing up as gtk-builder-tool stripping

It was previously a copy–paste of G_VALUE_COLLECT, which is wrong,
because it’s the inverse function of G_VALUE_COLLECT. Document that, so
the whole thing is a little less confusing (but by no means perfect).

Properly define GLIB/GOBJECT_STATIC_COMPILATION when static build is enabled.

This makes easier to write a module that can be both dynamic and static.
It will allow to statically build modules from glib-networking, for
example.
A module can rename its g_io_module_load() function to
g_io_<modulename>_load(), and then an application which links statically
against that module can call g_io_<modulename>_load(NULL) to register
types and extension points from the module. If a module is loaded
dynamically, its load() function will continue to be called with a
non-NULL GIOModule instance.

We should only emit C++ guards around the prototypes we include in the

Since --header --body has been deprecated and replaced with --body
--prototypes, the generated body is not wrapped with G_{BEGIN,END}_DECLS
any longer. Projects using C++ break due to that. Automatically wrap
prototypes individually in G_{BEGIN,END}_DECLS instead.

The Meson build has fallen a bit behind the Autotools one, when it comes
to the internally built tools like glib-mkenums and glib-genmarshals.
We don't need to generate gmarshal.strings any more, and since the
glib-genmarshal tool is now written in Python it can also be used when
cross-compiling, and without indirection, just like we use glib-mkenums.
We can also coalesce various rules into a simple array iteration, with
minimal changes to glib-mkenums, thus making the build a bit more
resilient and without unnecessary duplication.
The old glib-mkenums was more forgiving, and simply ignored any files it
could not find.
We're going to print a warning, as in the future we may want to allow
more strictness.
This is a bit of a hack to maintain some semblance of backward
compatibility with the old, Perl-based glib-mkenums. The old tool had an
implicit ordering on the arguments and templates; each argument was
parsed in order, and all the strings appended. This allowed developers
to write:
glib-mkenums \
--fhead ... \
--template a-template-file.c.in \
--ftail ...
And have the fhead be prepended to the file-head stanza in the template,
as well as the ftail be appended to the file-tail stanza in the
template. Short of throwing away ArgumentParser and going over
sys.argv[] element by element, we can simulate that behaviour by
ensuring some ordering in how we build the template strings:
- the head stanzas are always prepended to the template
- the prod stanzas are always appended to the template
- the tail stanzas are always appended to the template
Within each instance of the command line argument, we append each value
to the array in the order in which it appears on the command line.
This change fixes the libqmi build.
Some of the arguments that affect the generated result in glib-mkenums
can be used multiple times, to avoid embedding unnecessary newlines in
their values.
This change fixes the NetworkManager build.
When using the `--header --body` compatibility mode, we need to emit
things we generally define in the header, such as the aliases for
standard marshallers, and aliases for deprecated tokens.
This fixes dbus-binding-tool, which is using `--header --body` and
deprecated tokens.
