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. 79 * 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.
