72 * Stability and versioning definitions. These #defines are used in the tables
73 * of identifiers below to fill in the attribute and version fields associated
74 * with each identifier. The DT_ATTR_* macros are a convenience to permit more
75 * concise declarations of common attributes such as Stable/Stable/Common. The
76 * DT_VERS_* macros declare the encoded integer values of all versions used so
77 * far. DT_VERS_LATEST must correspond to the latest version value among all
78 * versions exported by the D compiler. DT_VERS_STRING must be an ASCII string
79 * that contains DT_VERS_LATEST within it along with any suffixes (e.g. Beta).
80 * You must update DT_VERS_LATEST and DT_VERS_STRING when adding a new version,
81 * and then add the new version to the _dtrace_versions[] array declared below.
82 * Refer to the Solaris Dynamic Tracing Guide Stability and Versioning chapters
83 * respectively for an explanation of these DTrace features and their values.
84 *
85 * NOTE: Although the DTrace versioning scheme supports the labeling and
86 * introduction of incompatible changes (e.g. dropping an interface in a
87 * major release), the libdtrace code does not currently support this.
88 * All versions are assumed to strictly inherit from one another. If
89 * we ever need to provide divergent interfaces, this will need work.
