The test has a custom .h target that has the same name as the input in the
test's source directory. Sometimes a compiler could build a target that
intends to use the file in the source tree, but finds an incomplete
output of the custom_target, causing the test to fail.
To fix this, move the generated headers in a subdirectory of the build
tree.

-m arguments aren't portable across architectures. -fipa-pta will
hopefully be portable for GCC, but also not implemented by clang.

We have two copies of other.h, one of which is generated. If we don't
include the include/ directory then building fails unless the
custom_target which copies it over, happens to run early enough. On
parallel builds this may fall on its face.

This allows us to ensure that the bindgen we're using is suitable for
our purpose.
|
|
Especially for C++ this is very important.
|
|
This may be of particular use when a header is .h but should be treated
as a C++ header instead of a C header.
|
|
Bindgen natively only considers .hpp to be C++ headers, but Meson
considers some additional extensions including .hh and .hxx to be C++.

This replaces all of the Apache blurbs at the start of each file with an
`# SPDX-License-Identifier: Apache-2.0` string. It also fixes existing
uses to be consistent in capitalization, and to be placed above any
copyright notices.
This removes nearly 3000 lines of boilerplate from the project (only
python files), which no developer cares to look at.
SPDX is in common use, particularly in the Linux kernel, and is the
recommended format for Meson's own `project(license: )` field

This does require hacking up the test pretty badly, since we need to not
ever pass GCC these invalid values. But it's preferable to writing
another project test I think.

This means that arguments set via `add_global_arguments`,
`add_project_arguments` and by either the `-Dc_args` or `CFLAGS` are
applied to bindgen as well. This can be important when, among other
things, #defines are set via these mechanisms.

During evaluation of codeblocks, we start off with an iteration of
nodes, and then while evaluating them we may update the global
self.current_node context. When catching and formatting errors, we
didn't take into account that the node might be updated from the
original top-level iteration.
Switch to formatting errors using self.current_node instead, to ensure
we can point at the likely most-accurate actual cause of an error.
Also update the current node in a few more places, so that function
calls always see the function call as the current node, even if the most
recently parsed node was an argument to the function call.
Fixes #11643

Allows getting closer to `./run_project_tests.py -- -Dwerror=true`.
- when argc and argv are not *both* used, there's a standard, compliant
mechanism to mark the variable as unused
- generated code should not build as -Werror
- more thoroughly comment out some commented code

This is needed for cases where we need external C headers, which are
passed to clang.
|
|
Which we support for basically every other case, but not this one.

This has a couple of advantages over rolling it by hand:
1. it correctly handles include_directories objects, which is always
handy
2. it correctly generates a depfile for you, which makes it more
reliable
3. it requires less typing
