56 56 * Stability and versioning definitions. These #defines are used in the tables
57 57 * of identifiers below to fill in the attribute and version fields associated
58 58 * with each identifier. The DT_ATTR_* macros are a convenience to permit more
59 59 * concise declarations of common attributes such as Stable/Stable/Common. The
60 60 * DT_VERS_* macros declare the encoded integer values of all versions used so
61 61 * far. DT_VERS_LATEST must correspond to the latest version value among all
62 62 * versions exported by the D compiler. DT_VERS_STRING must be an ASCII string
63 63 * that contains DT_VERS_LATEST within it along with any suffixes (e.g. Beta).
64 64 * You must update DT_VERS_LATEST and DT_VERS_STRING when adding a new version,
65 65 * and then add the new version to the _dtrace_versions[] array declared below.
66 66 * Refer to the Solaris Dynamic Tracing Guide Stability and Versioning chapters
67 67 * respectively for an explanation of these DTrace features and their values.
68 68 *
69 69 * NOTE: Although the DTrace versioning scheme supports the labeling and
70 70 * introduction of incompatible changes (e.g. dropping an interface in a
71 71 * major release), the libdtrace code does not currently support this.
72 72 * All versions are assumed to strictly inherit from one another. If
73 73 * we ever need to provide divergent interfaces, this will need work.

88 88 * previously worked; for example, adding a new built-in variable could break
89 89 * a script which was already using that identifier. The micro number should
90 90 * be changed when introducing functionality changes or major bug fixes that
91 91 * do not affect backward compatibility -- this is merely to make capabilities
