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

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