The easiest way to run the LLDB test suite is to use the <tt>check-lldb</tt> build
target. By default, the <tt>check-lldb</tt> target builds the test programs with
the same compiler that was used to build LLDB. To build the tests with a different
- compiler, you can set the <strong>LLDB_TEST_C_COMPILER</strong> or the <strong>LLDB_TEST_CXX_COMPILER</strong> CMake variables.
- These variables are ignored unless the respective <strong>LLDB_TEST_USE_CUSTOM_C_COMPILER</strong> and

+ compiler, you can set the <strong>LLDB_TEST_COMPILER</strong> CMake variable.
It is possible to customize the architecture of the test binaries and compiler used by appending -A
and -C options respectively to the CMake variable <strong>LLDB_TEST_USER_ARGS</strong>. For
example, to test LLDB against 32-bit binaries
