* 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.

Dependencies
Installing from source
Meson is available on PyPi, so
it can be installed with pip3 install meson. The exact command to
type to install with pip can vary between systems, be sure to use
the Python 3 version of pip.
If you wish you can install it locally with the standard Python command:
python3 -m pip install meson
For builds using Ninja, Ninja can be downloaded directly from Ninja GitHub release page or via PyPi
python3 -m pip install ninja
More on Installing Meson build can be found at the getting meson page.
Running
Meson requires that you have a source directory and a build directory
and that these two are different. In your source root must exist a
file called meson.build. To generate the build system run this
command:
meson setup <source directory> <build directory>
Depending on how you obtained Meson the command might also be called
meson.py instead of plain meson. In the rest of this document we
are going to use the latter form.
You can omit either of the two directories, and Meson will substitute the current directory and autodetect what you mean. This allows you to do things like this:
cd <source root>
meson setup builddir
To compile, cd into your build directory and type ninja. To run unit
tests, type ninja test.
More on running Meson build system commands can be found at the
running meson page
or by typing meson --help.
Contributing
We love code contributions. See the contribution page on the website for details.
IRC
The channel to use is #mesonbuild either via Matrix (web
interface) or OFTC IRC.
