In commit 8218aed118 (IntelLLVM: support marking include paths as SYSTEM
directories, 2023-08-15, v3.29.0-rc1~81^2) this flag was added for the C
and C++ compilers, but was accidentally added for Fortran too. Remove
it for the latter, as it is unsupported.
Issue: #25807
When cross-compiling, `clang-scan-deps` needs help to find the correct
location of core headers such as `stddef.h`. Always determine this path
and pass it when available.
Fixes: #25590
Apply the fix from commit 1ec6485c6a (Support duplicate object names in
large archives, 2014-04-16, v3.1.0-rc1~629^2) to the IPO-specific
archiving rules. Use "quick append" instead of "replace".
Fixes: #25675
Issue: #14874
Add TIClang compiler ID and support in compiler modules. Update
documentation. Add rudimentary RunCMake test for TIClang to test
basic functionality.
Fixes: #24619
When `clang-scan-deps` fails to scan (e.g., bad source syntax, junk
flags, etc.), the redirection unconditionally updates the file. If this
fails, the `.ddi` file timestamp is updated. If the state is then
reverted (e.g., the command line returns to the state of the last
successful build), the updated file is not useful, but `ninja` does not
rerun because:
- the command hash matches the last successful run
- the output file is newer than its inputs
However, since the `.ddi` file has been updated with bogus contents from
a failed scan, collation fails as the `rules` array is empty (or
incomplete from a batch scan).
If `clang-scan-deps` were properly aware of its output file, it could
use this to not write the file if any inner scan fails. Requested in
https://github.com/llvm/llvm-project/issues/72875.

Since commit a66004bee0 (Honor CMAKE_<LANG>_FLAGS[_<CONFIG>]_INIT set in
toolchain files, 2016-07-05, v3.7.0-rc1~392^2) we've accidentally been
adding extra optimization flags instead of replacing unwanted flags.

-fno-ansi-escape-codes is used only on Windows by Clang.
Without the flag color diagnostics are displayed only if clang.exe
is executed directly. Build tools like ninja and mingw32-make
will not display colored diagnostics.
Using -fno-ansi-escape-codes will make the build tools pass
the colored diagnostics to the calling application e.g IDE.
Fixes: #24235
In commit e9eabb0dcd (ADSP: Configure compiler in compiler module,
2022-03-24, v3.24.0-rc1~331^2~1) we added compiler information modules
for the ADSP C and C++ compilers. Add one for the assembler too.
We already identify the ADSP assembler since commit f83330ed6c (ASM:
ADSP assembler identification, 2018-01-30, v3.11.0-rc1~35^2).

The compiler does not yet support everything needed to integrate well
with the MSVC ABI, in particular for runtime library selection and debug
format selection. Document them in FIXME comments and leave this
support undocumented by CMake for now.

Update the Clang version checks added by
* commit eacacc70fc (Clang: use -std=c++23 for Clang 17.0+,
2023-05-08, v3.27.0-rc1~115^2)
* commit 0183956d30 (Clang: C++26 support,
2023-05-16, v3.27.0-rc1~85^2)
to account for Android NDK r26's distribution of a Clang based on a
development version of LLVM/Clang 17.0 that pre-dated addition of
these flags.
Follow the pattern from commit 12e6796b62 (Android: Do not pass
non-existent Clang -std flags, 2018-04-02, v3.12.0-rc1~284^2),
which fixed the same problem for `-std=c++17`.
