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

94 * The version number should be increased for every customer visible release
95 * of DTrace. The major number should be incremented when a fundamental
96 * change has been made that would affect all consumers, and would reflect
97 * sweeping changes to DTrace or the D language. The minor number should be
98 * incremented when a change is introduced that could break scripts that had
99 * previously worked; for example, adding a new built-in variable could break
100 * a script which was already using that identifier. The micro number should
101 * be changed when introducing functionality changes or major bug fixes that
102 * do not affect backward compatibility -- this is merely to make capabilities
103 * easily determined from the version number. Minor bugs do not require any
104 * modification to the version number.
