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

* incremented when a change is introduced that could break scripts that had
* previously worked; for example, adding a new built-in variable could break
* a script which was already using that identifier. The micro number should
* be changed when introducing functionality changes or major bug fixes that
