Update the archive rules added by commit 6e3655db2c (Clang: add LTO
support for GNU-command line clang on windows, 2019-07-08,
v3.16.0-rc1~161^2~3) to match the `ar` convention we use for normal
archives.
Issue: #21988
Extend the change from commit 39d0ade07e (Windows-GNU: Support duplicate
object names in large archives (#14874), 2014-04-14, v3.1.0-rc1~629^2~1)
to apply to the temporary archive we create for linking shared libraries
with MinGW tools.
Issue: #21988
Since CMake 3.19, we no longer support macOS SDKs older than 10.5,
which corresponds to Xcode 3. Supporting older Xcode versions for
device platforms is also not realistic. We therefore expect the -rpath
linker option should always be supported now.
When targeting iOS, tvOS or watchOS, the previous disabling of -rpath
support meant that the install_name_dir of shared libraries and
frameworks was unable to use @rpath. This resulted in embedding
absolute paths for their install_name. When they were embedded in an
app bundle, this would cause the app to fail at runtime. By enabling the
-rpath linker option, the default install_name_dir is now @rpath for these platforms, which results in binaries that do work at runtime.
Fixes: #20036
The change in commit 657fc3a9a7 (CMakeDetermineCompilerABI: Parse
library arch from versioned paths, 2021-02-03, v3.20.0-rc1~40^2) caused
`CMAKE_LIBRARY_ARCHITECTURE` to be populated on non-multiarch platforms
if their compilers happen to use `$arch/$version` library directories.
Revert the use of versioned library paths.

This should be front end compatible with vanilla clang but giving it a
unique identifier allows a project to pass additional options unique to
Fujitsu and outside the scope of a CMake builtin.
Set `CMAKE_SYSTEM_PROGRAM_PATH` in `Platform/Android-Initialize` instead
of `Platform/Android` so it can be used in `CMakeFindBinUtils`.
Also add the names `llvm-strip` and `llvm-ranlib` for the corresponding
tools.
Allows using different compilers with different flags for different languages.
For example Clang with GNU-like commandline for CXX and MSVC as host compiler
for CUDA.
Should help with #21914.

Some of the things are set in Platform/NVIDIA-CUDA and since we aren't setting
them to different values there's no point in overriding them.
Also fixed an unset() copy-paste error.
In commit bb61c2d024 (Clang: use -imsvc for system include dirs when
running on Windows, 2020-09-16, v3.19.0-rc1~162^2) we added `-imsvc`
for all Clang compilers targeting the MSVC ABI. However, the option
only exists for the MSVC-like front-end. The GNU-like front-ends
use `-isystem`.

Teach CMake how to extract `CMAKE_<LANG>_LIBRARY_ARCHITECTURE` from
versioned paths such as `/usr/lib/gcc/x86_64-linux-gnu/9`. These kind of
paths are generated by NVHPC compilers.
Using a single ID 'IntelLLVM' for the suite of Intel compilers based on
the LLVM backend. The 'IntelLLVM' ID are used for C, C++, and Fortran.
Data Parallel C++ will be handled in a separate commit.
The C and C++ definitions are based on the Clang definitions. The Intel
LLVM-based C and C++ compilers are based on the Clang front end, so
existing Clang options are more likely to be a good match than options
for the older Intel compilers.
Fortran is based on the older Fortran front end with the LLVM backend.
It has a similar interface to the older versions, though many options
are shared with the C and C++ compilers.

Identify the compilers as `NVHPC` to distinguish it from the older PGI
compilers from which they evolved, and from other `NVIDIA` compilers.
Fixes: #20887
The `-nofor_main` flag was originally added by commit ccdd3e943d (Fix
Intel Fortran SHARED libraries on Linux, 2009-10-27, v2.8.2~915). Since
then, Intel Fortran renamed the option to `-nofor-main` and deprecated
the old name. The new name has been available for a long time, so
we can just switch to it.

b7f0327dcd Tests: Cover macOS host architecture selection on Apple Silicon hosts
5f882f6ce5 macOS: Offer control over host architecture on Apple Silicon hosts
Acked-by: Kitware Robot <kwrobot@kitware.com>
Merge-request: !5589
Since commit b6c60f14b6 (macOS: Default to arm64 architecture on Apple
Silicon hosts, 2020-09-28, v3.19.0-rc1~63^2) we use `sysctl` to detect
that we are running on Apple Silicon in a way that pierces Rosetta.
This always sets `CMAKE_HOST_SYSTEM_PROCESSOR` to be `arm64` on such
hosts. However, macOS offers strong support for running processes under
an emulated `x86_64` architecture.
Teach CMake to select either `arm64` or `x86_64` as the host
architecture on Apple Silicon based on the architecture of its own
process. When CMake is built as a universal binary, macOS will select
whichever slice (architecture) is appropriate under the user's shell,
and `CMAKE_HOST_SYSTEM_PROCESSOR` will match.
Also offer a `CMAKE_APPLE_SILICON_PROCESSOR` variable and environment
variable to provide users with explicit control over the host
architecture selection regardless of CMake's own architecture.
Finally, if `CMAKE_OSX_ARCHITECTURES` is not set, pass explicit flags to
the toolchain to use selected host architecture instead of letting the
toolchain pick.

Each source compilation generates a dependencies file. These dependencies
files are consolidated in one file per target. This consolidation is done
as part of command 'cmake -E cmake_depends` launched before evaluation of
makefile dependency graph.
The consolidation uses the same approach as `CMake` dependencies management.
Fixes: #21321
These changes are in preparation of compiler generated dependencies support
for Makefiles generators
* compiler output and dependency target can be different for Makefiles generators
* resolve inconsistency naming for dependency file place-holder
The `/GR` flag has been on by default since MSVC cl 14.0 from VS 2005.
Remove it from the default flags to make it easier for projects to pass
`/GR-` themselves to turn it off.
Projects may be using string processing to replace `/GR` with another
flag, so we cannot simply drop it. Add a policy to drop it in a
compatible way.
Fixes: #21428
