Simply store the module it is expected to be found in. That module then
appends to the packages dict, which guarantees mypy can verify that
it's got the right type -- there is no casting needed.
llvm-config is unsuitable for standard cross-compile,
because we need to build llvm especially for it, which
is not done is almost any distros, so, for example,
standard bootstrap chroot will be unsuitable.
This patch is trying to acheive feature parity between
config-tool searching of LLVM and CMake-based one,
which is arch-agnostic.

There are lots of warnings that become fatal, that are simply unfixable
by the end user. Things like using old versions of software (because
they're using some kind of LTS release), warnings about compilers not
supporting certain kinds of checks, or standards being upgraded due to
skipped implementations (MSVC has c++98 and c++14, but not c++11). None
of these should be fatal, they're informative, and too important to
reduce to notices, but not important enough to stop meson if they're
printed.
There should be a way to make mypy happy without casting, but I can't
figure it out, since the mlog.error and mlog.debug actually have
different signatures.
Darwin-based systems, at least macOS, provide various JDK executable
stubs in
/System/Library/Frameworks/JavaVM.framework/Versions/*/Commands.
These stubs are placed in such a way that they break the heuristics of
the JNI system dependency. If a javac being analyzed to find a Java home
is a stub, use /usr/libexec/java_home.
See https://stackoverflow.com/a/15133344/7572728 for more details.
Closes#11173
Which catches a very real bug. The zlib system dependency failed to work
on MSVC since initial implementation in commit
c1a3b37ab7 -- it looked for the wrong
name.

Only import the ones we need for the language we are detecting, once we
actually detect that language.
This will allow finally dropping the main imports of these files in a
followup commit.
It turns out we don't generally need to proxy every compiler ever
through the top-level package. The number of times we directly poke at
one is negligible and direct imports are pretty clean.
A bunch of SystemDependency subclasses overrode log_tried() even though
they used the same function anyway. Delete them -- they still print
the same thing either way.
We use `__future__.annotations` to good effect everywhere we can, and
one of the effects of this is that annotations are automatically
stringized and don't need to be evaluated, using less memory and
computation. But this only affects actual annotations -- a cast is just
a function with an argument, so the compiler has no idea that it's an
annotation to be stringized.
Do this manually.
These are only used for type checking, so don't bother importing them at
runtime.
Generally add future annotations at the same time, to make sure that
existing uses of these imports don't need to be quoted.
JNI is a more apt name because it currently only supports the JNI. I
also believe that CMake uses the terminology JNI here as well.
JNI is currently the only way to interact with the JVM through native
code, but there is a project called "Project Panama" which aims to be
another way for native code to interact with the JVM.
All these dependencies are impossible to find on versions of Meson older
than the ones they got custom lookups in, because they don't provide
pkg-config files. So they should not / cannot be reasonably used on
older versions, and it is easy to say "yep, these should emit a
FeatureNew for the versions they got added in".
Contrary to most system method checks, zlib currently functions as a
whitelist of OSes. This isn't really needed however. The first special
case for OSes that provide zlib as part of the base OS is worth keeping.
However, the elif for windows is more than generic enough to allow any
other potential OSes to try. Just make it a simplie if/else instead.
Both of these are artifacts of the time before Dependency Factories,
when a dependency that could be discovered multiple ways did ugly stuff
like finding a specific dependency, then replacing it's own attributes
with that dependency's attributes. We don't have cases of that left in
the tree, so let's get rid of this code too
* dependencies: Deterministic LLVM compile and link arg ordering
In LLVMDependencyConfigTool, the members compile_args and required_modules are
either converted to or stored as sets, which do not have a stable ordering. This
results in nondeterministic builds, particularly with required_modules causing
the order in which the LLVM libraries are linked in to the output binaries to
change across independent builds. As any guarantee about ordering for
compile_args is lost by being converted from a list to a set and back, and the
modules added to required_modules was even already sorted once, sort both when
converting them to lists.
* Use mesonlib.OrderedSet instead of sorting the sets.

Instead of trying to cover everything internally
has_header returns a tuple of (found: bool, cached: bool), so `if
has_header` will always return true because the tuple is non-empty. We
need to check if the found value is true or not.
D lang compilers have an option -release (or similar) which turns off
asserts, contracts, and other runtime type checking. This patch wires
that up to the b_ndebug flag.
Fixes#7082
I've tested this on FreeBSD, and dragonfly's userland is close enough
I'm willing to call it good without testing. OpenBSD and NetBSD also
have a zlib in their base configurations, but I'm not confident enough
to enable those without testing.
This comes pre-installed, but currently we don't have a way to detect it
without relying on pkg-config or cmake. This is only valid with the
apple clang-based compilers, as they do some special magic to get
headers.
