41700ca4 SystemTools: Fix FileIsExecutable on Windows
This should avoid an exponential slowdown in the display time for
projects with lots of output.
This is still slower than cmake due to the ncurses drawing, but it should
now be O(L) in total and not O(L^2) wrt to output length.
Fixes: #20535
The `QUIET` mode suppresses any mention of our logged output, so do not
bother logging it. This also provides a way for users to avoid saving
possibly large output on disk.
Fixes: #20554
The output of gcov can be large and we only display it in a failure
case. Put it in a log file to avoid accumulating large output in
memory.
Issue: #20554
The `CMAKE_OSX_ARCHITECTURES` value is not used directly by generators.
It is used to initialize a per-target `OSX_ARCHITECTURES` property, but
that property can also be set explicitly by project code to a subset of
the full list of architectures. In order to handle this case, construct
a mapping from each `CMAKE_OSX_ARCHITECTURES` entry to the corresponding
`CMAKE_APPLE_ARCH_SYSROOTS` entry by name. Use the mapping to find the
sysroot for each entry in `OSX_ARCHITECTURES` for a given target.
If `CMAKE_APPLE_ARCH_SYSROOTS` does not have the same length as
`CMAKE_OSX_ARCHITECTURES`, error out early rather than risking a crash
or assertion failure.
Fixes: #20534
Use `<arch>-SDK-NOTFOUND` instead of an empty string as a placeholder in
`CMAKE_APPLE_ARCH_SYSROOTS` for architectures whose SDK is not found.
This ensures the length of `CMAKE_APPLE_ARCH_SYSROOTS` matches the
length of `CMAKE_OSX_ARCHITECTURES`. It also makes the missing SDKs
more visible in the value.

libuv upstream commit `2475296c` (build: make code compilable for iOS on
Xcode, 2020-01-18, v1.35.0~47) added a `defined(TARGET_OS_IPHONE)`
preprocessor condition, but `TARGET_OS_IPHONE` is always defined on
Apple to either 0 or 1.
libuv upstream commit `4a972bf0` (aix: Fix broken cmpxchgi() XL C++
specialization., 2019-09-06, v1.32.0~5) broke compilation with this
compiler. According to
https://www.ibm.com/support/knowledgecenter/SSGH3R_16.1.0/com.ibm.xlcpp161.aix.doc/migrate/migrate_to_xlclang.html
XLClang 16.1 for AIX does not support `__sync_val_compare_and_swap`.
The documentation suggests using C++11 atomic operations instead, but
this is C code. For now fall back to the non-atomic equivalent used
before so we can at least compile. Add a FIXME comment for this.
Since commit 1c2d031cbd (Add -E cmake_llvm_rc to preprocess files for
llvm-rc, 2020-01-14, v3.17.0-rc1~24^2) with llvm-rc we explicitly
preprocess RC source files and then compile separately without -I flags.
This broke cases where the RC source references data files adjacent to
itself or in the include path.
This change adds the expansion of the include paths when calling the
llvm-rc in order for the resource files to be picked up correctly by
llvm-rc. Since the RC compiled file is first preprocessed, the file
being compiled by llvm-rc resides in the build directory. In order for
llvm-rc to find the resource data specified relative to the .rc file
being compiled, the source file path is preppended in the include list
so that the original source path takes priority over all the other
includes paths specified.
A space was added in the CMAKE_INCLUDE_FLAG_RC to make the include
directive work properly for llvm-rc. Checks on the rc.exe showed that
the syntax change doesn't affect it's proper operation.
Fixes: #20529
On machines where the gnu bin utils are prefixed, or suffixed
the file(GET_RUNTIME_DEPENDENCIES ) command would fail without
explicitly setting the location of objdump.
Now we pre-populate the variables used to find objdump based
on the gnu bin utils, so that these use cases are better supported
