Some of the generated qapi-types-MODULE.h are included all over the place. Changing a QAPI type can trigger massive recompiling. Top scorers recompile more than 1000 out of some 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h): 6300 qapi/qapi-builtin-types.h 5700 qapi/qapi-types-run-state.h 3900 qapi/qapi-types-common.h 3300 qapi/qapi-types-sockets.h 3000 qapi/qapi-types-misc.h 3000 qapi/qapi-types-crypto.h 3000 qapi/qapi-types-job.h 3000 qapi/qapi-types-block-core.h 2800 qapi/qapi-types-block.h 1300 qapi/qapi-types-net.h Clean up headers to include generated QAPI headers only where needed. Impact is negligible except for hw/qdev-properties.h. This header includes qapi/qapi-types-block.h and qapi/qapi-types-misc.h. They are used only in expansions of property definition macros such as DEFINE_PROP_BLOCKDEV_ON_ERROR() and DEFINE_PROP_OFF_AUTO(). Moving their inclusion from hw/qdev-properties.h to the users of these macros avoids pointless recompiles. This is how other property definition macros, such as DEFINE_PROP_NETDEV(), already work. Improves things for some of the top scorers: 3600 qapi/qapi-types-common.h 2800 qapi/qapi-types-sockets.h 900 qapi/qapi-types-misc.h 2200 qapi/qapi-types-crypto.h 2100 qapi/qapi-types-job.h 2100 qapi/qapi-types-block-core.h 270 qapi/qapi-types-block.h Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Tested-by: Philippe Mathieu-Daudé <philmd@redhat.com> Message-Id: <20190812052359.30071-3-armbru@redhat.com>
