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

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