65 * Stability and versioning definitions. These #defines are used in the tables
66 * of identifiers below to fill in the attribute and version fields associated
67 * with each identifier. The DT_ATTR_* macros are a convenience to permit more
68 * concise declarations of common attributes such as Stable/Stable/Common. The
69 * DT_VERS_* macros declare the encoded integer values of all versions used so
70 * far. DT_VERS_LATEST must correspond to the latest version value among all
71 * versions exported by the D compiler. DT_VERS_STRING must be an ASCII string
72 * that contains DT_VERS_LATEST within it along with any suffixes (e.g. Beta).
73 * You must update DT_VERS_LATEST and DT_VERS_STRING when adding a new version,
74 * and then add the new version to the _dtrace_versions[] array declared below.
75 * Refer to the Solaris Dynamic Tracing Guide Stability and Versioning chapters
76 * respectively for an explanation of these DTrace features and their values.
77 *
78 * NOTE: Although the DTrace versioning scheme supports the labeling and
79 * introduction of incompatible changes (e.g. dropping an interface in a
80 * major release), the libdtrace code does not currently support this.
81 * All versions are assumed to strictly inherit from one another. If
82 * we ever need to provide divergent interfaces, this will need work.
