`volatile` was previously mistakenly used in GLib to indicate that a
variable was accessed atomically or otherwise multi-threaded. It’s not
meant for that, and up to date compilers (like gcc-11) will rightly warn
about it.
Drop the `volatile` qualifiers.
Based on a patch by Jeff Law.

So that editors that can fold code (vim, vscode, etc) can correctly fold
functions, instead of getting confused by code that doesn't follow the
current indention. Also, it makes the code easier to read.
Also, remove the possibility of passing in a compiler instance to
min_driver_version. This is because the NVCC compiler instance is,
as of CUDA Toolkit 11.0, no longer guaranteed to be versioned
identically to the toolkit itself.
Some license identifiers are ambiguous (e.g. "GPL3"). The SPDX license
identifiers avoid this by providing standardized and unique identifiers
(e.g. "GPL-3.0-only" or "GPL-3.0-or-later" for the previous example).
Because SPDX short-form identifiers are also both human- and
machine-readable we should recommend them in the documentation.

Using the std option, so now `rust_std=..` will work. I've chosen to use
"std" even though rust calls these "editions", as meson refers to
language versions as "standards", which makes meson feel more uniform,
and be less surprising.
Fixes: #5100
Right now sub-sub projects are not correctly registered, because we
don't have a way to pass up past the first level of subproject. This
patch changes that by making the build_Def_files as defined in the
Interpreter initializer accurate for translated dependencies, ie, cmake
dependencies won't define a dependency on a non-existent meson.build.
This means that it can always add the subi.build_def_files because they
are always accurate.
Subprojects that use the CMake PCH feature will cause
compilation/linker errors. The CMake PCH support
should thus be disabled until this can be properly
translated to meson.

Instead of trying to cover everything internally
When glib is a subproject we should use glib-compile-resources it
overrides using find_program() in the case it is not installed on the
build machine. With old glib version we have to run
glib-compile-resources at configure time to generate the list of
dependencies, but not when glib is recent enough.
wraps from subprojects are now merged into the list of wraps from main
project, so they can be used to download dependencies of dependencies
instead of having to promote wraps manually. If multiple projects
provides the same wrap file, the first one to be configured wins.
This also fix usage of sub-subproject that don't have wrap files. We can
now configure B when its source tree is at
`subprojects/A/subprojects/B/`. This has the implication that we cannot
assume that subproject "foo" is at `self.subproject_dir / 'foo'` any
more.
Sometimes, distros want to configure a project so that it does not
use any bundled library. In this case, meson.build might want
to do something like this, where slirp is a combo option
with values auto/system/internal:
slirp = dependency('', required: false)
if get_option('slirp') != 'internal'
slirp = dependency('slirp',
required: get_option('slirp') == 'system')
endif
if not slirp.found()
slirp = subproject('libslirp', ...) .variable('...')
endif
and we cannot use "fallback" because the "system" value should never
look for a subproject.
This worked until 0.54.x, but in 0.55.x this breaks because of the
automatic subproject search. Note that the desired effect here is
backwards compared to the policy of doing an automatic search on
"required: true"; we only want to do the search if "required" is false!
It would be possible to look for the dependency with `required: false`
and issue the error manually, but it's ugly and it may produce an error
message that looks "different" from Meson's.
Instead, with this change it is possible to achieve this effect in an
even simpler way:
slirp = dependency('slirp',
required: get_option('slirp') != 'auto',
allow_fallback: get_option('slirp') == 'system' ? false : ['slirp', 'libslirp_dep'])
The patch also adds support for "allow_fallback: true", which is
simple and enables automatic fallback to a wrap even for non-required
dependencies.
Currently if you change the `choices` field in the meson_options.txt
file, no update will be done until `meson setup --wipe` is called. Now
if the choices change then the options will be properly merged.
If the currently select value is still valid it is guaranteed to be
kept, if it is now invalid the new default value will be used and a
warning will be printed.
Fixes#7386
`pathlib.Path.glob()` also returns directories that match source
filenames (i.e. a directory named `test.h/`), but `clang-format` and
`clang-tidy` fail when handed a directory. We manually skip calling
`clang-format` and `clang-tidy` on those directories.
This is required to make the various keys in the [user options] section
work the same as they do in the meson_options.txt file, where we don't
have any rules about case sensitivity.
There is some risk here. Someone may be relying on this lower by default
behavior, and this could break their machine files.
Fixes#7731
There are two cases that won't work (these are taken from fortran/9
cpp), using gfortran with a non-gcc compiler on windows, or using
gfortran with apple clang. The latter is due to default search paths,
which we can fix, but is out of scope for this MR.
This is a test for https://github.com/mesonbuild/meson/pull/7021, to
verify that `link.exe` uses the correct architecture when targeting
ARM64. Can be extended to other cross targets later.
