11 * As a temporary measure while the headers are being untangled, define
12 * __XEN_TOOLS__ here before any Xen headers are included. Otherwise, if
13 * the Xen toolstack library headers are later included, they will find
14 * some of the "internal" definitions missing and the build will fail. In
15 * later commits, we'll end up with a rule that the native libraries have
16 * to be included first, which will ensure that the libraries get the
17 * version of Xen libraries that they expect.
11 * C files using Xen toolstack libraries will have included those headers
12 * already via xen_native.h, and having __XEM_TOOLS__ defined will have
13 * automatically set __XEN_INTERFACE_VERSION__ to the latest supported
14 * by the *system* Xen headers which were transitively included.
15 *
16 * C files which are part of the internal emulation, and which did not
17 * include xen_native.h, may need this defined so that the Xen headers
18 * imported to include/hw/xen/interface/ will expose the appropriate API
19 * version.
20 *
21 * This is why there's a rule that xen_native.h must be included first.
