* LCC: Add dedicated support for MCST LCC compilermakise-homura2021-10-159-0/+366
| | | | | | | | | | | | | | | | | | | | | Divert LCC compiler as a new one, instead of treating it as GNU. Since old times, Elbrus C/C++/Fortran Compiler (LCC) by MCST has been passing checks for GNU compilers, so it has been identified as GNU. Now, with intent of seriously upstreaming its support, it has been added as a separate LCC compiler, and its version displays not a supported GCC version, but LCC version itself (e.g. LCC 1.25.19 instead of GNU 7.3.0). This commit adds its support for detection, and also converts basically every check like 'is this compiler GNU?' to 'is this compiler GNU or LCC?'. The only places where this check is untouched, is where it regards other platforms where LCC is unavailable (primarily non-Linux), and where it REALLY differs from GNU compiler. Note: this transition may break software that are already ported to Elbrus, but hardly relies that LCC will be detected as GNU; still such software is not known.

* | | cmStandardLevelResolver: Avoid unnecessary flags, fix unset level logicRaul Tambre2021-09-292-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The changes are part of CMP0128. When the standard level is unset: * Flags are added if extension mode doesn't match the compiler's default. Previously logic only worked if LANG_EXTENSIONS was ON. Fixes #22224. * The full flag is used. Previously CMAKE_LANG_EXTENSION_COMPILE_OPTION was used. This was only supported for IAR. Otherwise: * Avoid adding flags if not necessary per the detected compiler defaults. * Fixed check for when the requested standard is older. It now matches the nearby comments. I reworded the fallback comment as its logic was a bit difficult to wrap my head around.

|/ / | | | | | | | | | | | | | | | | | | There was a mismatch in the executable suffix between the compiler detection and try_compile. This resulted in the generated executable having a different suffix than what try_compile was looking for. The IAR module is changed to use the same suffix as try_compile. Fixes: #22567

| * HIP: Simplify detection of HIP runtime CMake packageBrad King2021-09-161-1/+1
| | | | | | | | | | | | | | It only makes sense to use the CMake package from the same ROCm installation that the compiler uses. Ask the HIP compiler to report the location of the ROCm installation. Verify up front that it contains the expected CMake package file.
| * HIP: Remove ROMClang compiler id and use Clang directlyBrad King2021-09-169-134/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit bd844387df (ROCMClang: Add the ROCm toolkit derived clang compiler to CMake, 2020-08-28, v3.21.0-rc1~66^2~6) and commit ff0d2858e1 (HIP: Extract clang compiler details from hipcc, 2020-10-21, v3.21.0-rc1~66^2~5), the separate `ROCMClang` compiler id for `hipcc` has caused a few problems: * The compiler id changed from behavior of CMake 3.20 and below, breaking projects that already built with `hipcc` treated as `Clang`. * The implementation of `target_compile_features` was incomplete for the `ROCMClang` identity. * Only `hipcc` was identified as `ROCMClang`, so after it is unwrapped to the underlying `clang++`, future runs of new CMake versions on an existing build tree would not repeat this. * Clang should be usable as a HIP compiler without the `hipcc` wrapper. Remove the `ROMClang` compiler identity, and revise HIP language support to work directly with a Clang compiler. Reject direct `hipcc` usage as a HIP compiler. For now it cannot be supported because it interferes with flags CMake needs to pass to Clang. Fixes: #22536, #22460, #22593

| * ARMClang: Fix regression in check for working compilerLingkai Dong2021-07-141-11/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Given the compiler to use, `CMakeFindBinUtils.cmake` automatically determines a number of tools including linker (CMAKE_LINKER) and archiver (CMAKE_AR) and stores them in a generated file `CMakeCCompiler.cmake` as non-CACHE entries. The compiler-specific ARMClang.cmake then tries to override CMAKE_LINKER and CMAKE_AR as CACHE entries. Following the introduction of CMP0126, which is set to NEW in the test for a working compiler, setting a CACHE entry does not replace a normal entry of the same name anymore, resulting in a failed test due to wrong linker and archiver. To fix this, set CMAKE_LINKER and CMAKE_AR for ARMClang directly in `CMakeFindBinUtils.cmake` as is done for other compilers. Check for them in `ARMClang.cmake` to safeguard cases when a project explicitly includes `ARMClang.cmake` prior to compiler determination (which some projects do to work around other problems in older CMake versions).
