Compiler id for IBM Clang-based XL compilers is now ``XLClang``.
|
|
|
|
CMake 3.15 and above recognize that IBM's Clang-based XL compilers
|
|
that define ``__ibmxl__`` are a new front-end distinct from ``xlc``
|
|
with a different command line and set of capabilities.
|
|
CMake now prefers to present this to projects by setting the
|
|
:variable:`CMAKE_<LANG>_COMPILER_ID` variable to ``XLClang`` instead
|
|
of ``XL``. However, existing projects may assume the compiler id for
|
|
Clang-based XL is just ``XL`` as it was in CMake versions prior to 3.15.
|
|
Therefore this policy determines for Clang-based XL compilers which
|
|
compiler id to report in the :variable:`CMAKE_<LANG>_COMPILER_ID`
|
|
variable after language ``<LANG>`` is enabled by the :command:`project`
|
|
or :command:`enable_language` command. The policy must be set prior
|
|
to the invocation of either command.
|
|
|
|
The ``OLD`` behavior for this policy is to use compiler id ``XL``. The
|
|
``NEW`` behavior for this policy is to use compiler id ``XLClang``.
|
|
|
|
This policy was introduced in CMake version 3.15. Use the
|
|
:command:`cmake_policy` command to set this policy to ``OLD`` or ``NEW`` explicitly.
|
|
Unlike most policies, CMake version |release| does *not* warn
|
|
by default when this policy is not set and simply uses ``OLD`` behavior.
|
|
See documentation of the
|
|
:variable:`CMAKE_POLICY_WARNING_CMP0089 <CMAKE_POLICY_WARNING_CMP<NNNN>>`
|
|
variable to control the warning.
