The DT_ATTR_* macros are a convenience to permit more 74 * concise declarations of common attributes such as Stable/Stable/Common. The 75 * DT_VERS_* macros declare the encoded integer values of all versions used so 76 * far. DT_VERS_LATEST must correspond to the latest version value among all 77 * versions exported by the D compiler. DT_VERS_STRING must be an ASCII string 78 * that contains DT_VERS_LATEST within it along with any suffixes (e.g. Beta). 79 * You must update DT_VERS_LATEST and DT_VERS_STRING when adding a new version, 80 * and then add the new version to the _dtrace_versions[] array declared below. 81 * Refer to the Solaris Dynamic Tracing Guide Stability and Versioning chapters 82 * respectively for an explanation of these DTrace features and their values. 83 * 84 * NOTE: Although the DTrace versioning scheme supports the labeling and 85 * introduction of incompatible changes (e.g. dropping an interface in a 86 * major release), the libdtrace code does not currently support this. 87 * All versions are assumed to strictly inherit from one another.
