According to ARMClang documentation 6.20, the patch version number
should not include the last two digits of `__ARMCOMPILER_VERSION`,
which are reserved for internal use by ARM.
FreeBSD installs both LLVM and gcc with tools named after the
major version, in the form "clang<major>", such as "clang16".
Detect compilers named this way, and find the related toolchain
tools.
Revert commit 6b58cdd4cf (Ninja: Exclude NVHPC -Werror flags during
Fortran preprocessing, 2023-04-04). Since commit 9d40f01442 (NVHPC: Use
-Werror for COMPILE_OPTIONS_WARNING_AS_ERROR, 2023-04-13), `nvfortran`
can handle the plain `-Werror` flag during preprocessing.
Issue: #24665
The IAR linker silencer flag was previously hardcoded in
`CMAKE_${lang}_LINKER_EXECUTABLE`. Move the flag to a place that is
under the end user's control. The default behavior (silenced linker) is
not changed.
Fixes: #24828
The previously-used `-Werror all-warnings` is not supported by
the NVHPC suite of compilers. This previously worked since `-Werror`
was being used and `all-warnings` was being excluded.
We thought this was the correct syntax due to incorrect documentation
about `-Werror`, which stated the argument should be space-separated,
while it should actually be separated with `=` or `,`.
Issue: #24665
The Ninja generator preprocesses Fortran separately in order to scan for
module dependencies. NVHPC's `nvfortran` does not support its `-Werror`
flag while preprocessing with `-E`, so filter it out.

The settings added by commit 3fe8e33f27 (Clang: Record Clang 16.0 flags
for our experimental C++ modules support, 2023-03-03, v3.26.0-rc6~6^2)
work only for the GNU-like `clang++` front-end, and not for the
MSVC-like `clang-cl` on Windows.
Also quote the path to `clang-scan-deps` to support spaces in its path.
Issue: #24611
If a project or user sets a variable or cache entry named `C` or `CXX`,
we were previously comparing those language names to the value of that
variable, rather than the name itself. Double-quote the string to take
advantage of policy `CMP0054`, but also add "x" prefixes to support
projects that do not set the policy.
This extends a similar fix from commit c8eb357738 (CompilerId: Tolerate
variables named for languages, 2021-06-17, v3.21.0-rc1~9^2).
LCC < 1.24 has no way to disable integrated Fortran preprocessor,
and it can't produce preprocessed files explicitly. So we
disable all functionality (and therefore tests) related to it.
LLVM Flang's preprocessor output is always valid fixed form Fortran with
a fixed line length of 72. If an application tries to use fixed form
with a different line length, this will fail in the
post-preprocessing compilation step as they will pass a flag asking for
a different fixed line length.
To fix this we can pass -ffixed-line-length-72 to the post-preprocess
compilation stage. This will be ignored when the input is free form
Fortran, and force to a 72 line length when the input is fixed.
This variable has been provided since commit 746906242d (Android: Detect
NDK version number, 2021-02-26, v3.20.0-rc3~1^2~3) when using CMake's
NDK support or the modern NDK toolchain file. Since commit 005e2cdfb0
(Android: Do not use gold for ndk >= r22, 2021-02-26, v3.20.0-rc3~1^2)
we need the value in our compiler/platform information files, so provide
it when using the NDK legacy toolchain file too.
Revert commit 1c86e397fe (Android/Clang: Tolerate undefined
CMAKE_ANDROID_NDK_VERSION, 2022-09-16, v3.25.0-rc1~118^2) since the
variable should now always be defined.

Replace old-style `file(APPEND .../CMake{Output,Error}.log)` logging
with calls to `message(CONFIGURE_LOG)` to record the steps in the
`CMakeConfigureLog.yaml` configure log instead.
Issue: #23200
The IntelLLVM compiler, for compatibility with MSVC on Windows, always
runs with support for at least C++14. The `-Qstd=c++11` flag just
causes a warning that it is unused.
Fixes: #24316
Don't initialize the other CMAKE_<LANG>_COMPILER_PREDEFINES_COMMAND
variables.
The only language variant that is used is
CMAKE_CXX_COMPILER_PREDEFINES_COMMAND, and the other language variants
contained invalid, namely C++-specific commands.
Fixes: #23968
