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