**LLVM_ENABLE_WERROR**:BOOL
Stop and fail build, if a compiler warning is triggered. Defaults to OFF.
+**LLVM_ABI_BREAKING_CHECKS**:STRING
+ Used to decide if LLVM should be built with ABI breaking checks or
+ not. Allowed values are `WITH_ASSERTS` (default), `FORCE_ON` and
+ `FORCE_OFF`. `WITH_ASSERTS` turns on ABI breaking checks in an
+ assertion enabled build. `FORCE_ON` (`FORCE_OFF`) turns them on
+ (off) irrespective of whether normal (`NDEBUG` based) assertions are
+ enabled or not. A version of LLVM built with ABI breaking checks
+ is not ABI compatible with a version built without it.
+
**LLVM_BUILD_32_BITS**:BOOL
Build 32-bits executables and libraries on 64-bits systems. This option is
available only on some 64-bits unix systems. Defaults to OFF.
**LLVM_USE_SANITIZER**:STRING
Define the sanitizer used to build LLVM binaries and tests. Possible values
- are ``Address``, ``Memory``, ``MemoryWithOrigins`` and ``Undefined``.
- Defaults to empty string.
+ are ``Address``, ``Memory``, ``MemoryWithOrigins``, ``Undefined``, ``Thread``,
+ and ``Address;Undefined``. Defaults to empty string.
**LLVM_PARALLEL_COMPILE_JOBS**:STRING
Define the maximum number of concurrent compilation jobs.
