| |
| MSVC is not an assembler for language ASM. |
| |
| When enabling the ``ASM`` language, CMake considers C compiler drivers |
| as assembler candidates. CMake 4.0 and below accidentally selected |
| MSVC's ``cl`` compiler as the ``CMAKE_ASM_COMPILER``, allowing the ``ASM`` |
| language to be enabled on Windows even though ``cl`` does not support |
| assembler sources. CMake 4.1 and above prefer to reject ``cl`` as an |
| assembler candidate, but some existing projects unconditionally enable |
| ``ASM`` on Windows even though they add no assembler sources. This |
| policy provides compatibility for such projects to allow them to |
| configure as before. |
| |
| The ``OLD`` behavior for this policy is to successfully enable ``ASM`` |
| even if ``cl`` is the only available candidate. The ``NEW`` behavior |
| for this policy is to not consider ``cl`` as a candidate assembler |
| for the ``ASM`` language. |
