| |/ | | | | | | | | | | | | | | | | LLVM/Clang 20, when invoked as `clang++ -E -c ...`, now warns: warning: argument unused during compilation: '-c' Drop the unnecessary `-c` flag. Also add a `-w` flag to suppress warnings so their text is not parsed as predefines.

MSVC documentation states that the flag will be removed in the future when `-std:c++23` is added. Therefore it is only suitable for manual specification by end-users. Issue: #26692

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Tasking ASM information module was added by commit 94df5b6ef1 (Tasking: Add support for several compiler toolsets, 2022-07-20, v3.25.0-rc1~133^2). However, it appears to have been left from pattern following and did not actually work with the Tasking assembler. Update it to work when running the assembler through the compiler driver `cctc`, which supports extensions `.asm` and `.src`. Fixes: #26425

The `<FLAGS>` placeholder is for executables. The `<LANGUAGE_COMPILE_FLAGS>` placeholder is for shared libraries. The distinction is for historical reasons. Fixes: #26563

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was added in commit 98d0f918ba (LFortran: Add support for this compiler, 2024-01-25, v3.31.0-rc1~303^2~2) because it is needed for cases covered by CMake's Fortran tests. However, it does not work with Fortran modules and breaks lfortran's own `examples/project1`. Move the flag to the test cases that need it, just as the original commit did with `--implicit-interface`. Fixes: #26597 Co-authored-by: Brad King <brad.king@kitware.com>

| * VS: Restore support for mixing C++23 and C in one target with clang-clBrad King2024-12-091-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | Since commit 474eafe28c (clang-cl: Add support for C++23, 2024-09-13, v3.31.0-rc1~97^2) we use a Clang-specific flag to enable C++23 since `clang-cl` has no `-std:c++23` flag, and `-std:c++latest` may enable an even newer version of C++. However, in `.vcxproj` files there is no way to express a target-wide `-clang:-std=c++23` flag for only C++ sources when the target also has C sources. Add a special case to map back to `-std:c++latest` for targets with C++23 and C together. Fixes: #26508
* | IBMClang: Express compiler information as a Clang variantDavid Tenty2024-12-047-90/+24
| | | | | | | | | | | | | | | | | | | | De-duplicate IBMClang compiler information by detecting the base clang version and following the same logic as we do for any other clang of that version. This helps maintain support for new IBMClang features inherited from new base Clang versions. We already use this approach for other Clang variants, like CrayClang and FujitsuClang.

* | ARMClang: Remove orphaned linker --list optionDaniel Brondani2024-11-181-1/+1
|/ | | | | | | | | | | | | Setting the `armlink --list` option without other diagnostic flags is misleading because it produces an empty file and prevents the user from printing diagnostics to the standard output or redirecting them to another file. It's unclear why the flag was added when support for ARMClang was first added by commit 7b0abaac31 (ARMClang: Add support for Clang-based ARM compiler, 2019-05-13, v3.15.0-rc1~111^2). Fixes: #21538

* clang-cl: Add support for C++23Brad King2024-09-131-3/+11
| | | | | | | | Although there is no `cl -std:c++23` flag, the underlying Clang compiler does have a C++23 mode we can activate by passing `-std=c++23` through a `clang-cl` wrapper flag. Fixes: #26061
