The following patches will modify the test visitor to check the value is correctly saved, and generate #if/#endif code (as a single #if/endif line or a series for a list). Example of 'if' key: { 'struct': 'TestIfStruct', 'data': { 'foo': 'int' }, 'if': 'defined(TEST_IF_STRUCT)' } The generated code is for now *unconditional*. Later patches generate the conditionals. A following patch for qapi-code-gen.txt will provide more complete documentation for 'if' usage.
