This commit adds the `no_strict_aliasing` flag, which disables
the strict aliasing rule, for the GCC compiler and its derivatives.
Signed-off-by: Stephanos Ioannidis <root@stephanos.io>
This commit adds a template for specifying the C/C++ compiler flag for
disabling the strict aliasing rule.
It also enables this flag globally because the Zephyr codebase does not
strictly adhere to the aliasing rules specified by the C/C++ standards
and the optimisation strategies that assume these rules may end up
generating invalid code.
For instance, GCC 11 and above tend to optimise more aggressively
assuming the strict adherence to the standard aliasing rules and may
generate invalid code, when compiling Zephyr with `-fstrict-aliasing`,
that results in various run-time failures.
Note that the footprint and performance ramifications of disabling the
strict aliasing rule are negligible.

Updates the ztest_test_fail() function to allow failures in setup.
When executed, a failed assert will fail every test in the suite owning
the setup function. This was verified by adding a suite which asserts
in the setup function and has a test that should pass. During
exeuction, ztest marks the test as failing.
In order to verify exection I also added 2 new APIs:
- ZTEST_EXPECT_FAIL(suite_name, test_name)
- ZTEST_EXPECT_SKIP(suite_name, test_name)

This file is no longer used by device.h, so let's avoid spending time
generating the content formerly in it.
In order to leave a pointer in place for users who are expecting to
see it or are pulling it into their own builds, however, replace its
contents with an #error directive that tells them what happened. This
can be removed later on when we expect people are used to the
transition.

So, introduce config DCLS that is enabled by default if

This commit allows a project to specify a given set of Kconfig targets

This commit allows for specifying a dedicated Kconfig namespace, for
example: <namespace>_CONFIG
This namespace will then be used for handling loading of configuration
files into CMake configure scope, as well as handling of CMake cache
variables when set using `-D<namespace>_CONFIG_<var>=<value>`.
This allows greater flexibility when re-using the cmake/kconfig.cmake
in other projects.

DTS directories can come from multiple places. Some places like a user's
CMakeLists.txt can preserve symbolic links. Others like
`scripts/zephyr_module.py --settings-out` resolve symbolic
links.
list(REMOVE_DUPLICATES ...) does not know anything about directories;
only about strings. To fix it the de-duplication, resolve all symbolic
links in DTS_ROOT first using file(REAL_PATH ...).
Fixes this somewhat confusing error:
```
-- Found BOARD.dts: /home/proj/mymodule/boards/myboard/myboard.dts
devicetree error: both /home/proj/mymodule/dts/bindings/intel,stuff.yaml
and /disk1/home/proj/mymodule/dts/bindings/intel,stuff.yaml

```
Also, print `gen_defines.py` arguments in case of an error so anyone can
see what failed and not just west+CMake experts.

zephyr_library_compile_options() was attempting to create
unique hashes for compile options in order to prevent creating
them multiple times. However, it was only using the first
argument to create the hash, so if multiple libraries had
different compile options but the first line was the same,
the second set would be mistaken for the first set and would
actually be passed the first set during compilation instead
of its own set.
The fix should be to use the entire compile options argument
list to create the hash so they should only match if the entire
options list is exactly the same.
This is a continued fix for #43835

This commit updates the Zephyr build system to support specifying
advanced floating-point compilation options derived from the newly
introduced unified floating-point configurations.
The following changes are introduced by this commit:
1. Specify architecture floating-point option to the `-mcpu` flag.
2. Specify floating-point unit (FPU) type using the `-mfpu` flag.
Note that the `-march` flag is not specified separately because the
`-mcpu` flag provides more detailed architecture options and this
makes the `-march` flag redundant.
