`link.exe /lib` is an undocumented flag and it just calls `lib.exe`.
Also `link.exe` doesn't parse the `/lib` option correctly when in a
response file.
Since commit 1c2d031cbd (Add -E cmake_llvm_rc to preprocess files for
llvm-rc, 2020-01-14, v3.17.0-rc1~24^2) we pass the full target `<FLAGS>`
to the llvm-rc resource compiler, but we should pass only `<DEFINES>`.
Fixes: #20414
Add an additional include flag to PCH usage command line to fix programs
that rely on `compile_commands.json` file. Pass it to the preprocessor
directly to avoid compiler driver to change it to '-include-pch'.
When preprocessor is requested to preprocess a file, it tries to get
the original filename from '.pch' and uses that file for preprocessing.
CMake generates a '.pch' file from the '.hxx' file by passing an empty
'.cxx' source file to the compiler as a compilation unit and the header
file with the '-include' flag. After that, compiler puts compilation
unit filename in the '.pch' as the original filename.
However, CMake build system uses empty file as the source file and
passes the header file using '-include-pch' flag. As a result, Clang
uses the wrong file for preprocessing and produces the corrupted
preprocessed file.

Populate `CMAKE_Swift_IMPLICIT_INCLUDE_DIRECTORIES` with the macOS SDK's
include directory so that we filter such implicit directories out of
Swift targets.
Fixes: #19845
llvm-rc requires preprocessed rc files. The CMake command line tool
cmake_llvm_rc enables channing the preprocessor call and the resource
compiler and make this appear as single compilation step.
When llvm-rc is detected as resource compiler, the RC compilation step
is set to use this command.
In commit 97bca2f9fa (Android: Use unified toolchain in NDK r19+,
2019-07-26, v3.16.0-rc1~342^2) we hard-coded use of the unified
toolchain for NDK r19+ and skipped most of the old detection logic.
However, in that fast path we left out setting `_CMAKE_TOOLCHAIN_PREFIX`
for `CMakeFindBinutils` to select the matching binutils. Add it.
Fixes: #20038
This allows building .s/.S assembly code, and makes sure that the
`-fPIC` option isn't passed to the compiler (as it errors out on
Clang and causes a loud warning on GCC).
Since commit 0f150b69d3 (AIX: Explicitly compute shared object exports
for both XL and GNU, 2019-07-11, v3.16.0-rc1~418^2~2) we always export
all symbols from shared libraries by default. Add a new target property
called `AIX_EXPORT_ALL_SYMBOLS` that can be explicitly set to OFF to
suppress this behavior and export no symbols by default.
Fixes: #20290
In commit 0f150b69d3 (AIX: Explicitly compute shared object exports for
both XL and GNU, 2019-07-11, v3.16.0-rc1~418^2~2) we dropped use of the
old `CMAKE_XL_CreateExportList` cache entry for XL exports. However,
some people were setting the value to an empty string as a way to
disable automatic export of symbols. Restore this behavior when the
option is explicitly set to an empty string.

Fixes#17559
Replace our hard-coded default of cudart=static with a first-class abstraction to select the runtime library from an enumeration of logical names.
Modern distributions of packages built with MinGW tools provide `.dll.a`
import libraries. Prefer those instead of finding plain `.dll` files.
This avoids accidentally finding unrelated Windows `.dll` files.
Fixes: #20019
Add a `JOB_POOL_PRECOMPILE_HEADER` target property to specify the pool
name, and its associated `CMAKE_JOB_POOL_PRECOMPILE_HEADER` variable.

This moves the definition of the import library flags for Windows into a
platform specific file (much like the Darwin `-sdk` flag). This is in
preparation for re-use of the flag to make the flags handling for
executables more precise.

Starting with CUDA 10.2 the nvcc compiler has gained support
to automatically forward unknown flags to the host compiler.
This behavior is highly desired as projcts that mix CUDA, C, C++
run into situation where flags such as `-pthread` which aren't
supported by nvcc, are being applied to all source files and
therefore break CUDA compilation.

Pass the value to the Swift compiler driver via `-sdk`. We already do

The CMake support for Android assumes cross-compilation using the NDK,
so stub out that Android NDK support and use the Linux support that's
already invoked. Set CMAKE_HOST_SYSTEM_NAME to "Android", rather than
"Linux".
